Ivermectin is present at doses of 10 mg per mL, which is adequate to treat 110 lb (50 kg) of body weight (maximum 10 mL per injection site.).

Antiparasitic medication ivermectin is used. It was first used in veterinary medicine to prevent and treat heartworm and acariasis after being discovered in 1975.

A steroid is not ivermectin. Drugs called steroids behave similarly to cortisol and work to reduce edoema in the body. Prednisolone, betamethasone, and other typical steroids are listed below. Ivermectin, on the other hand, is an anthelmintic medication.

Barbiturates (such as phenobarbital and butalbital), benzodiazepines (such as clonazepam and lorazepam), sodium oxybate (GHB), and valproic acid are a few of the medications that may interact with this medication.

Thus, Ivermectin is present at doses of 10 mg per mL, which is adequate to treat 110 lb (50 kg) of body weight (maximum 10 mL per injection site.)

- Oil Energy is a Major Source of Pollution and Damage Made to the Environment Every Year.

- Oil Like the Other Fossil Fuels Is A Finite Resource.

- Emissions Produced by Oil Causes Acid Rain

-Plastic is One of the Products Obtained Through Oil Refining.

- Working in the Oil Sector Can Be a Dangerous Activity.

hope this is good enough :)

Answer:

Pros: Oil can easily be transported by a network of pipelines.

Oil-fired power stations can, in theory, be built almost anywhere.

The oil is burned to heat water and produce steam. This steam propels the blades of a turbine. This is attached to a generator, which produces electricity.

Cons: Oil is a non-renewable source of energy. This means that one day we will probably run out of crude oil.

Burning oil produces carbon dioxide gas. This is a greenhouse gas that contributes towards climate change.

Burning oil can pollute the air.

Much of our oil has to be imported and it is becoming more and more expensive as reserves reduce and imports increase.

Producing electricity from crude oil is expensive compared to other fossil fuels such as coal or gas.

Explanation:

The sugar is added into the water, then the sugar will dissolve into the water.

Answer:

you have a 3.17molal solution: This is 3.17mol CaCl2 dissolved in 1 litre of water. Make this solution.  

Molar mass CaCl2 = 110.9848 g/mol

3.17mol = 3.17*110.9848 = 351.822g  

Total mass = 1000g H2O + 351.822g CaCl2 = 1,351.822g  

Volume of this solution:

Volume = mass / density

Volume = 1,351.822/1.24  

Volume = 1,090.2 mL  

You have 3.17mol CaCl2 dissolved in 1,090.2 mL solution

Mol CaCl2 dissolved in 1000mL solution =  1000/1090.2*3.17 = 2.91 mol CaCl2

The question is incomplete, the complete question is;

In the 1800s, a popular belief known as vitalism stated that life processes could not be explained by the laws of physics and chemistry,and were instead dictated by an independent life force. Which discovery most likely caused scientists to revise this hypothesis regarding the origin of life on Earth?

a. that inorganic compounds existed within live organisms

b. that organic compounds could be synthesized in a laboratory

c. that RNA could serve as a template to synthesize DNA

d. that self-replicating molecules existed inside cells

Answer:

b. that organic compounds could be synthesized in a laboratory

Explanation:

Vitalism is the belief that "living organisms are fundamentally different from non-living entities because they contain some non-physical element or are governed by different principles than are inanimate things"(wikipedia).

This theory held that the molecules involved in life processes could not be synthesized in the laboratory.

All these were upturned after Fredrich Whöler's synthesis of urea in 1828. He was able to show that molecules involved in life process can also be synthesized in the laboratory. This gave rise to modern synthetic organic chemistry.

Answer:

Mass = 0.96 g

Explanation:

Given data:

Volume of oxygen = 840cm³

Temperature = at room = 25°C

Pressure = at room = 1 atm

Mass of oxygen = ?

Solution:

Volume of oxygen = 840 cm³ × 1 L /1000 cm³ = 0.84 L

Temperature  = 25 +273.15k = 298.15 K

Formula:

PV = nRT

n = PV/RT

R = 0.0821 atm.L/mol.K

n = 1 atm × 0.84 L / 0.0821 atm.L/mol.K ×  298.15 K

n = 0.84 atm.L / 24.48 atm.L/mol

n = 0.03 mol

Mass of oxygen:

Mass = number of moles × molar mass

Mass = 0.03 mol × 32 g/mol

Mass = 0.96 g

Explanation:

Answer:

See explanation below (Brainlist please)

Explanation:

First of all, we need to understand what is an acidic hydrogen.

An acidic hydrogen, is the atom of hydrogen which is more propense to undergo an acid base reaction, and form a stable ion or molecule in the process.

In other words, is the hydrogen that is more vulnerable to get substracted in an acid base reaction to form another compound.

Knowing this information, gives us an idea of how a molecule can be formed and which kind of compound is formed.

Now, in this question, we have 5 molecules. Each of them is either a ketone or aldehyde, so this mean that we have the carbonile group (C = O), which means that is easier to identify the acidic hydrogen. This is because the Carbonile group is an attractor group, so, it will attract the charges by inductive effect (in some cases by resonance), and the molecule is more stable.

This can be shown by drawing the enolate ion that is formed once the molecule undergo the acid base reaction. As it's an enolate form that we are looking for, then it means that the ketone or aldehyde is undergoing an electrofilic attack with a base. This base will substract the most acidic hydrogen to form a better and stable enolate. The acidic hydrogen and the enolate form can be seen in the attached picture.

a) In the case of acetaldehyde, the most acidic will be the hydrogen of carbon 2, because the hydrogen from the carbonile, once it's substracted, the charge of the carbon cannot be stabilized by resonance. Carbon 2 hydrogens, can do this job easily.

b) Propanal happens something similar to acetaldehyde, the terminal hydrogen cannot be substracted, and carbon 3, once the hydrogen is gone, the negative charge cannot be stabilized by resonance, so hydrogens of carbon 2 can do this.

c) in the case of acetone, is easier to look because we only have the C = O between two methyl group, so you can use either carbon 1 or 3 to do the job.

d) 4 heptanone the most acidic hydrogen would be carbon 3 or 5, because they are closer to the C=O and the ion can be stabilized by resonance.

e) Finally in ciclopentanone, the most acidic hydrogen would be carbon 2 or 5.

See picture for a better understanding.

Answer:

The correct option is a

Explanation:

First ionization energy is the minimum amount of energy required to remove the most loosely bound electron (valence electron) from the outermost shell of a gaseous or neutral atom. Since it takes more amount of energy to remove more electrons, it (ionization energy) generally increases across the period and decreases down a group because the closer the outermost shell is to the nucleus, the more difficult/energy required to remove electrons in that shell.

Since magnesium and phosphorus are on the same period (period 3), it can be deduced from the explanation above that phosphorus has a greater first ionization energy than magnesium because phosphorus (5 valence electrons) has more electrons in it's outermost shell than magnesium (2 valence electrons).

Explanation:

Fundamentally the aluminum foil is a rectangular prism. It has a length, a width, and a thickness.

The volume of a rectangular prism is expressed as

[tex]V = l * w * h[/tex]

If we know the volume and two of the three dimensions, we can rearrange the equation to solve for the thickness.

[tex]h = V/(l*w)[/tex]

But we should also be sure to confirm our units.

A liter is defined as 1000 cm^3. Therefore a mL is equal to 1 cm^3.

You should convert the units of measure given in the problem statement such that the units are aligned. For example, 10.0mm will be 1 cm and 12.5m will be 1250 cm. This will give you a height in cm.

Explanation:

In this case, I will put the original photo of this exercise, because we are missing one data. The first picture is the original exercise.

Now, according to this, we need to make a serial dilution of CO(NO₃)₂. We don't know the volume of this solution, but we do know the total volume of the preparing solution (In the picture states that the total volume will be 10 mL).

So, we know the final volume of the solutions to be prepared, so, le'ts use the expression that will help us to solve this:

C₁V₁ = C₂V₂

Where:

C₁: Concentration of the given solution (stock)

V₁: volume required to prepare the dilluted solution

C₂; Concentration of the dilluted solution

V₂: Total volume of the dilluted solution.

Now that we know the expression to use and the meaning of each value, let's prepare the solutions:

To prepare 10 mL of 0.1 M using a 0.25 M, we will replace these values in the above expression; from there, we will solve for V₁, that value will tell us the required volume to prepare solution 2, and then, by difference we can calculate the volume of water:

Volume of water (Vw) =V₂ - V₁  

Now replacing the values:

0.25V₁ = 0.1 * 10

V₁ = 1/0.25 = 4 mL

This means that we need 4 mL of the stock to prepare the 0.1 M of dilluted solution, therefore, the volume of water required is:

Vw = 10 - 4

Using these same steps for the other two solutions we will get V1 and V2 for both of them. In this case, I will go straight to the procedure without further explanation because it's the same of this one.

For solution 2:

0.1V₁ = 0.05 * 10

V₁ = 0.5/0.1

Vw = 10 - 5

Finally for solution 3:

V₁ = 0.01 * 10 / 0.05

Vw = 10 - 2 mL

Hope this helps

[tex]m_{PbI_3}=383.05gPbI_3[/tex]

Explanation:

Hello!

In this case, since the reaction between lead and iodine is:

[tex]2Pb+3I_2\rightarrow 2PbI_3[/tex]

We can see there is 2:2 and 3:2 mole ratio between each reactant and the product; in such a way, for the limiting reactant we must compute the moles of lead (III) iodide yielded by each reactant first:

[tex]n_{PbI_3}^{by\ Pb}=135gPb*\frac{1molPb}{207.2gPb}*\frac{2molPbI_3}{2molPb} =0.652molPbI_3\\\\n_{PbI_3}^{by\ I_2}=338gI_2*\frac{1molI_2}{253.81gI_2}*\frac{2molPbI_3}{3molI_2} =0.888molPbI_3[/tex]

Thus, the limiting reactant is lead because it yields the fewest moles of product. Next, we compute the mass of lead (III) iodide by multiplying the produced 0.652 moles by its molar mass:

[tex]m_{PbI_3}=0.652molPbI_3*\frac{587.91gPbI_3}{1molPbI_3} \\\\m_{PbI_3}=383.05gPbI_3[/tex]

Solution

Redox reactions in water electrolysis :

Anode: 2H2O (l) → O2 (g) + 4H⁺ (aq) + 4e

Cathode: 4H2O (l) + 4e → 2H2 (g) + 4OH⁻ (aq)

Reaction: 2H2O → 2H2 (g) + O2 (g)

mol H₂ :

n = PV/RT

n = (1 atm x 1 L)/(0.082 x 298)

n = 0.041

From reaction at cathode : mol ratio of electron and H₂ = 4 : 2, so mol electrons :

= 4/2 x mol H₂

= 2 x 0.041

= 0.082

1 Faraday is the amount of electricity that is passed in the electrolysis cell to obtain 1 mole of electrons.
