a patient is prescribed tigan capsules for vomiting. The drug is available in the form of 300.0 mg tigan/capsules ,and is administered in 4.0 doses/day of 1 capsule/dose. How many g Tigan does the patient recieve in 2.0 days?

Answers

The patient recieves 2.4 g Tigan in 2 days

Further explanation

In finding the conversion units, we can multiply and eliminate the same units so that we can get the desired quantity or unit.

In this case, it is expected that the number of Tigan is known in 2 days, so we just need to multiply the numbers that are known

[tex]\tt =300\dfrac{mg}{capsules}\times \dfrac{1~capsules}{dose}\times 4.0\dfrac{doses}{day}\times 2.0~days\\\\=300\times 1\times 4.0\times 2.0~mg=2400~mg=\boxed{\bold{2.4~g}}[/tex]

Which process is represented by this diagram?

Answers

Answer:distillation

Explanation:

The process represented by the diagram is chromatography.

What is chromatography?

Chromatography is a separation technique used to separate components present in a mixture.It makes use of two phases the stationary phase and mobile phase .

Stationary phase is a phase in which the mixture  components to be separated is loaded. Mobile phase is a phase which is run  over the stationary phase so as to enables components of mixtures to separate.

Separation of components is based on the principle that components of mixture which are soluble in mobile phase travel large distances over stationary phase while those which are insoluble or less soluble travel less distances over stationary phase.

For every component which is separated, a Rf value can be calculated which is simply ratio distance traveled by solute divided by distance traveled by solvent front.

If an astronomer was to look through a telescope and notice that a star's emitted light had a slightly red tint to it, compared to what the emitted light should be. What would that mean about that star?

Answers

Answer:

In the chapters that follow, we will provide the temperature of the stars we are describing, and this section tells you how those temperatures are determined from the colors of light the stars give off. Hubble Space Telescope image of the Sagittarius Star Cloud. The image shows many stars of various colors, white, blue, red and yellow spread over a black background. The most common star colors in this image are red and yellow. Figure 1: Sagittarius Star Cloud. This image, which was taken by the Hubble Space Telescope, shows stars in the direction toward the center of the Milky Way Galaxy. The bright stars glitter like colored jewels on a black velvet background. The color of a star indicates its temperature. Blue-white stars are much hotter than the Sun, whereas red stars are cooler. On average, the stars in this field are at a distance of about 25,000 light-years (which means it takes light 25,000 years to traverse the distance from them to us) and the width of the field is about 13.3 light-years. (credit: Hubble Heritage Team (AURA/STScI/NASA))

Color and Temperature

As we learned in The Electromagnetic Spectrum section, Wien’s law relates stellar color to stellar temperature. Blue colors dominate the visible light output of very hot stars (with much additional radiation in the ultraviolet). On the other hand, cool stars emit most of their visible light energy at red wavelengths (with more radiation coming off in the infrared) (Table 1). The color of a star therefore provides a measure of its intrinsic or true surface temperature (apart from the effects of reddening by interstellar dust, which will be discussed in Between the Stars: Gas and Dust in Space). Color does not depend on the distance to the object. This should be familiar to you from everyday experience. The color of a traffic signal, for example, appears the same no matter how far away it is. If we could somehow take a star, observe it, and then move it much farther away, its apparent brightness (magnitude) would change. But this change in brightness is the same for all wavelengths, and so its color would remain the same. Table 1. Example Star Colors and Corresponding Approximate Temperatures

Star Color Approximate Temperature Example

Blue 25,000 K Spica

White 10,000 K Vega

Yellow 6000 K Sun

Orange 4000 K Aldebaran

Red 3000 K Betelgeuse

Go to this interactive simulation from the University of Colorado to see the color of a star changing as the temperature is changed. The hottest stars have temperatures of over 40,000 K, and the coolest stars have temperatures of about 2000 K. Our Sun’s surface temperature is about 6000 K; its peak wavelength color is a slightly greenish-yellow. In space, the Sun would look white, shining with about equal amounts of reddish and bluish wavelengths of light. It looks somewhat yellow as seen from Earth’s surface because our planet’s nitrogen molecules scatter some of the shorter (i.e., blue) wavelengths out of the beams of sunlight that reach us, leaving more long wavelength light behind. This also explains why the sky is blue: the blue sky is sunlight scattered by Earth’s atmosphere.

Color Indices

In order to specify the exact color of a star, astronomers normally measure a star’s apparent brightness through filters, each of which transmits only the light from a particular narrow band of wavelengths (colors). A crude example of a filter in everyday life is a green-colored, plastic, soft drink bottle, which, when held in front of your eyes, lets only the green colors of light through. One commonly used set of filters in astronomy measures stellar brightness at three wavelengths corresponding to ultraviolet, blue, and yellow light. The filters are named: U (ultraviolet), B (blue), and V (visual, for yellow). These filters transmit light near the wavelengths of 360 nanometers (nm), 420 nm, and 540 nm, respectively. The brightness measured through each filter is usually expressed in magnitudes. The difference between any two of these magnitudes—say, between the blue and the visual magnitudes (B–V)—is called a color index. By agreement among astronomers, the ultraviolet, blue, and visual magnitudes of the UBV system are adjusted to give a color index of 0 to a star with a surface temperature of about 10,000 K, such as Vega. The B–V color indexes of stars range from −0.4 for the bluest stars, with temperatures of about 40,000 K, to +2.0 for the reddest stars, with temperatures of about 2000 K. The B–V index for the Sun is about +0.65. Note that, by convention, the B–V index is always the “bluer” minus the “redder” color. Why use a color index if it ultimately implies temperature? Because the brightness of a star through a filter is what astronomers actually measure, and we are always more comfortable when our statements have to do with measurable quantities.

Microwave Miracle: Patrick believes that if fish eat microwaved food then they be able to swim through a maze faster. He decides to perform an experiment by placing fish food in a microwave for 20 seconds. He has the fish swim through a maze and records the time it takes for each one to make it to the end. He feeds the microwaved food to 10 fish (group A) and gives regular food to 10 others (group B). After 1 week, he has the fish swim through the maze again and records the times for each. Which fish are in the control group? * Group A Group B Microwaved Food Non-microwaved Food

Answers

Answer:

Group B

Explanation:

The fish in group B are those in the control group.

A control group during an experiment represents a group of the subject that is subjected to all experimental variables except the independent variable - the manipulate-able variable that is supplied by the experimenter which directly affects the dependent variable.

In this case, the independent variable is the type of food given to the two groups of fishes - microwaved or regular food while the dependent variable is the time it takes for the fishes to swim through the maze. Since the focus of the experiment is to see if microwaved food enhances the swimming speed of fishes, the group of fish that receives microwaved food would represent the treatment group while those that received regular food would be the control group.

Hence, group B represents the control group.

A fluoride ion (F) has the same electron configuration as
A. Na+
B.Na
C.Cl-
D.Cl

Answers

Answer:

Option A. Na⁺

Explanation:

Floride ion (F¯) simply indicates that the fluorine atom has gain an extra electron.

Thus, the electronic configuration of the fluoride ion (F¯) can be written as follow:

F¯ (10) => 1s² 2s²2p⁶

Next, we shall determine the electronic configuration of the element given in options to see which is the same as that of the fluoride ion (F¯). This is illustrated below:

Na⁺ (10) => 1s² 2s²2p⁶

Na (11) => 1s² 2s²2p⁶ 3s¹

Cl (17) => 1s² 2s²2p⁶ 3s²3p⁵

Cl¯ (18) => 1s² 2s²2p⁶ 3s²3p⁶

From the above illustrations, we can see that the fluoride ion (F¯) has the same electronic configuration as Na⁺.

Each element is made up of electrons and these electrons are filled in different shells. These are the following shells in the electrons:

K shellL shellM shellN shell

According to the question, the fluoride ion has 10 electrons in its 2 shells, that is 2 in K shell and 8 in L shell.

A similar number of shell and electrons to the fluoride ion is sodium ion ([tex]Na^{+}[/tex])

The [tex]Na^+[/tex]has a total 10 number of electrons, hence the electronic configuration is 2 and 8.

Therefore, the [tex]Na^+[/tex] is the correct option.

Answers

Answer: C

Explanation:

The N2 should have a triple bond because it needs three covalent bonds to fill its outer shell. This means the two atoms need to share three electrons each.

It also serves as a nice illustration of a triple-bonded molecule. For the Lewis structure of N2, there are ten accessible valence electrons. Therefore, option C is correct.

What is lewis structure ?

The diagrams known as Lewis structures, often referred to as Lewis dot formulas, Lewis dot structures, electron dot structures, or Lewis electron dot structures, depict the interactions between the atoms in a molecule as well as any lone pairs of electrons that may be present.

It contradicts the octet rule, as shown by the production of molecules, and could not account for the release of energy during the formation of covalent bonds.

The three parallel lines between the N atoms represent three bonds. This is a triple bond, with one electron from each N atom contributing to each bond. A total of 6 electrons are thus represented by this triple bond.

Thus, option C is correct.

The particle that is labeled with a question mark (?) in the diagram is Quarks

Quarks are elementary particles and fundamental constituents of matter. They are considered the smallest known particles that make up protons and neutrons, which are the building blocks of atomic nuclei. Quarks are classified as fermions, which means they follow the rules of quantum mechanics and obey the Pauli exclusion principle.

There are six known types, or flavors, of quarks: up (u), down (d), charm (c), strange (s), top (t), and bottom (b). Each quark flavor has a unique set of properties, including mass, electric charge, and the way they interact with other particles through the strong nuclear force. The up and down quarks are the lightest and most common, while the top quark is the heaviest.

One notable property of quarks is that they possess a fractional electric charge. The up quark has a charge of +2/3 (e/3), while the down quark has a charge of -1/3 (-e/3), where "e" represents the elementary charge carried by an electron. Quarks are never found in isolation due to the confinement principle, which means they are always bound together in composite particles called hadrons.

Quarks interact through the strong nuclear force, which is mediated by particles called gluons. This force binds quarks together to form protons and neutrons, and also governs the interactions within atomic nuclei.
