Answer:

B. Particles of liquid water have more energy than particles of ice.

Explanation:

We can work this out through eliminating the wrong statements.

A. Both liquid water and ice have definite shapes.

This is wrong because, as stated in the question, water is a liquid, and one of the properties of liquids is that they change shape to fit the shape of their container. If it changes shape, it does not have a "definite" shape.

B. Particles of liquid water have more energy than particles of ice.

This is correct, and here is why. There are 3 states of matter: solid, liquid and gas. As you apply heat energy to an object at each state, the particles receive more energy and can move around more (this is kinetic energy). In the case of liquid (water) and solid (ice), particles in solids do not have much energy and stay in rigid formations. They do vibrate slightly, but only on the spot (this is what gives solids "definite" shapes). On the other hand, particles in liquids have more energy than particles in solids, which means that they can move more (more kinetic ENERGY) and do not stay in formations (this is why they do not have "definite" shapes). Therefore, particles in liquids (water) have more energy than particles in solids (ice), and this statement is correct.

C. Liquid water has a lower temperature than ice.

This is wrong because liquids have more energy than solids. As explained earlier, the reason why particles in liquids have more energy is because more HEAT energy has been applied to them. In the same way, solids have less energy because less HEAT energy has been applied to them. Less heat means a lower temperature. (Also you can use common sense for this one, ice feels colder than liquid water, right?)

D. Ice has a definite volume, but liquid water does not.

This is wrong because of the law of conservation of mass. This law states that particles (or matter or volume) cannot be created or destroyed. When ice melts and becomes liquid water, it has not lost volume: the particles have just gained more energy. This question is most likely there to confuse you, because all substances have definite volumes.

Answer: b

Explanation:

The most likely ion of Phosphorous is P³⁻ (group 15) since gaining three electrons is the most energetically favorable way for it to follow the octet rule.

Because the charge on ions is equivalent to their oxidation state, then -3 is the most likely oxidation number of Phosphorous.

A reagent us a chemical substance applied in a chemical reaction to bring about a change in the chemical reaction process. The reagent that is appropriate to carry out the conversion is Ethanol (CH3CH2OH).

Organic Reactions are reactions taking place in organic compounds and they can take various forms such as electrophilic addition reaction or nucleophilic substitution reactions.

From the assumed diagram below, the reaction takes place in an unimolecular nucleophilic reaction SN1 mechanism in which a racemic mixture produce an organic compound and an enantiomer.

For the reaction to take place, the best organic reagent to us is known as ethanol (CH3CH2OH). This is because the organic reagent is a solvent that acts as a Nucleophile.

In the reaction, bromine (Br) is the leaving group, after it detaches from the racemic compound, it forms a carbonation in which the Ethanol CH3CH2OH attacks at the carbonation site.

Therefore, we can conclude that the Reagent necessary to carry out the conversion is Ethanol (CH3CH2OH)

Answer:

Pigments in the light-harvesting complex pass light energy to two special chlorophyll a molecules in the reaction center. The light excites an electron from the chlorophyll a pair, which passes to the primary electron acceptor. The excited electron must then be replaced.

Explanation:

During photosynthesis,the electrons that are excited by the energy in sunlight first come from chlorophyll pigment present in the leaves.

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.

Answser:

This sunflower must be a young one because a sunflower turns toward the sun when they are young. Once they mature they will prematurally stay facing east. with this knowledge we can exclude some of tghe answers and leave the correct one remaining. It is not C becasue sunflowers do not hibernate. They lay dormante in the winter waiting for their seeds to pop out during the spring. it is not D becasue Gravitropism is a form of facing towards or away from the pull of gravity. It is nopt A because it is to simalir to Hidernation. Dormancy is staying dormant during cool temputure and ect. So our answer must be B because Phototropism is the condition that a plant growes toward light. this is why bannanas are curved and why trees grow up. So your your answer is B Phototropism.

Answer:

4.64E14

Explanation:

First convert 645 nm to m = 6.4500E-7m. The equation for finding v with these values is the speed of light/wavelength. so 2.998E8/6.4500E-7m.

so your v or frequency would equal 4.64E14

Fun fact you know this is visible light because the visible light range is within the E14 range.

Answer:

(n, l, m sub l, m sub s)

N: principle quantum number (1,2,3,4,etc)

l: angular momentum quantum number, the shape (l has to be at least 1 less than n, but can be 0 depending on n)

M sub l: magnetic quantum number (l determines this number)

M sub s: spin quantum number (can only ever be 1/2 or -1/2)

Explanation:

The principle, azimuthal, magnetic, and spin quantum numbers specify the principle shell, the shape of the orbital, the number of orbitals, and electron spin respectively.

The set of numbers that describes the position and energy of the electron are called quantum numbers. Four quantum numbers are principal, azimuthal, magnetic, and spin quantum numbers.

Principal quantum numbers (n) designate the principal electron shell of the atom and the most probable distance between the nucleus and the electrons. A larger value of the principal quantum number indicates a large distance between the electron and the nucleus.

The azimuthal quantum number (l) describes the shape of an orbital in which an electron is present. Its value is equal to the total number of angular nodes in that orbital.

The magnetic quantum number describes the total number of orbitals in a subshell and the orientation of these orbitals.  The value of the spin quantum number (s) offers the direction in which the electron is spinning and it has only two possible values +½ and -½.
