Answers

Answer 1

Liquid acetaminophen for children is labeled 180 mg 3 ml. The strength expressed as grams per ml is 0.060.

What is acetaminophen?

Acetaminophen is a medicine that is used to treat all kind of pains. Headache, menstrual pain, stomach ache, etc. It also used to reduce fever and cold/cough.

Liquid acetaminophen for children is labeled as 180 mg/ 3ml

The 180 mg will be divided by 3 ml

180 mg/ 3ml = 60 mg/ml

The amount will be multiplied by 1 /1000 to get the quantity equal.

60 mg/ml x 1g / 1000 g

60 x 1/ 1000 mg/ml = 0.060

Thus, the strength expressed as grams per ml is 0.060.

A solution has a poh of 7. 1 at 10∘c. what is the ph of the solution given that kw=2. 93×10−15 at this temperature? remember to report your answer with the correct number of significant figures

Answers

A solution has a pOH of 7. 1 at 10∘c. Then the pH of the solution given that kw=2. 93×10−15 at this temperature is 7.4 .

It is given that,

pOH of solution = 7.1

Kw =2.93×10^(-15)

Firstly, we will calculate the value of pKw

The expression which we used to calculate the pKw is,

pKw=-log [Kw]

Now by putting the value of Kw in this expression,

pKw =−log{2.93×10^(-15)}

pKw =15log(2.93)

pKw=14.5

Now we have to calculate the pH of the solution.

As we know that,

pH+pOH=pKw

Now put all the given values in this formula,

pH+7.1=14.5

pH=7.4

Therefore, we find the value of pH of the solution is, 7.4.

When 20. 0 g nh3 and 50. 0 g o2 are allowed to react, which is the limiting reagent?

Answers

When 20. 0 g NH₃ and 50. 0 g O₂ are allowed to react, NH₃ is the limiting reagent.

What is limiting reagent ?

Limiting reagent is defined as that reactant in a chemical reaction which is completely consumed in reaction.

Given,

Mass of NH₃ = 20 g

Mass of O₂ = 50 g

Molecular mass of NH₃ = 14 + 7 = 17 g

Molecular mass of O₂ = 2 × 16 = 32 g

Mole = given mass/ molecular mass

Mole of ammonia = 20/17

                             = 1.17 mole

Moles of O2 = 50/32

                    = 1.56 mole

Chemical equation:

4NH₃(g) + 3O₂(g)  ⟶ 2N₂(g) +6H₂O

From above reaction it is clear that 4 moles of NH₃ react with 3 moles of oxygen.

So, 1 mole of ammonia react with = 3/4 moles of O₂

                                                       = 0.75 moles of O₂

Also, 1.18 moles of ammonia react with

= 1.18 × 0.75

= 0.885 moles of O₂

Thus, from above we concluded that ammonia is completely consumed in reaction. Therefore ammonia is limiting reagent.

Adding heat to a substance group of answer choices sometimes does not result in a temperature change. always results in a temperature increase. sometimes results in results in a temperature decrease.

Answers

Sometimes adding heating of substance set of answer options does not cause a change in temperature. resulting in an increase in temperature every time. results occasionally in a drop in temperature.

A substance's atoms and molecules move more quickly when it is heated. Whether the substance is a solid, liquid, or gas, this occurs. However, the temperature does not always rise when more heating of substance is added. For instance, adding heat to boiling water will not raise its temperature. This occurs when the heating of the substance reaches its boiling point, which is for all vaporizable substances. The average kinetic energy of the molecules will fluctuate when a system gains or loses heat. So long as a phase shift is not taking place, heat transfer causes a change in the system's temperature.

How does the enthalpy of photosynthesis compare to the
enthalpy of cellular respiration?

Answers

The results of photosynthesis are used by cellular respiration, and photosynthesis first uses the results of cellular respiration.

Enthalpy of photosynthesis and cellular respiration:

In the mitochondria, cellular respiration combines oxygen and glucose to produce ATP, along with water and carbon dioxide. Sunlight energy is used during photosynthesis to create glucose and separate oxygen from carbon dioxide and water. Globally, the exchange of carbon dioxide and oxygen during photosynthesis or cellular respiration serves to maintain stable levels of oxygen and carbon dioxide in the atmosphere.

Cellular Respiration: [tex]C_6H_1_2O_6+ 6O_2[/tex] → [tex]6CO_2 + 6H_2O[/tex]

Because CO₂ and H₂O are less energetic than the reactants, most notably glucose, the reaction is exothermic and has a negative enthalpy (ΔH < 0). This also makes sense because breathing causes glucose to be converted to energy.

How can we increase the rate of collisions between the reactants in this reaction? mg 2hcl → mgcl2 h2

Answers

The frequency of collisions between the two reactants increases as the concentration of the reactants increases. When collisions happen, they don't always cause a reaction (atoms misaligned or insufficient energy, etc.). Higher concentrations result in more collisions and reaction opportunities.

Increasing a reactant's surface area increases the frequency of collisions and thus the reaction rate. The surface area of several smaller particles is greater than that of a single large particle. The greater the available surface area for particles to collide, the faster the reaction will occur.

How does concentration affect the rate of collisions between reactants?

Thus, we can conclude that by increasing the concentration of Mg in the reaction mixture we increase the rate of collisions between the reactants in this reaction.

Dilution is the process of lowering a solute's concentration in a solution. It usually just involves mixing the solution with more solvent, and much more water. A solution is diluted when more solvent is added without increasing solute. The final mixture is thoroughly mixed to make sure that every component is the same.

The formula for the dilution of a solution is

                                       M₁V₁ = M₂V₂

where,

M is molarity and V is the volume of the solution in liters.

Considering the Dalton's partial pressure, the total pressure in the mixture of gases is 1.371 atm.

The pressure exerted by a particular gas in a mixture is known as its partial pressure.

So, Dalton's law states that the total pressure of a gas mixture is equal to the sum of the pressures that each gas would exert if it were alone:

[tex]P_{T}[/tex] = [tex]P_{1}+P_{2}+......+P_{n}[/tex]

where n is the amount of gases in the mixture.

Dalton's partial pressure law can also be expressed in terms of the mole fraction of the gas in the mixture.  So in a mixture of two or more gases, the partial pressure of gas A can be expressed as:

[tex]P_{A}[/tex] = [tex]X_{a}P_{T}[/tex]

In this case, the partial pressure of gas H₂ can be expressed as:

[tex]P_{H2}[/tex] = [tex]X_{H2} P_{T}[/tex]

You know:

[tex]P_{H2}[/tex] = 0.48 atm

[tex]X_{H2}[/tex] = 0.35

Replacing in the definition of partial pressure of gas H₂:

[tex]0.48atm = 0.35P_{T}[/tex]

Solving:

[tex]P_{T}[/tex] = [tex]\frac{0.48atm}{0.35}[/tex]

[tex]P_{T}[/tex]= 1.371 atm

In summary, the total pressure in the mixture of gases is 1.371 atm.

Thermite is a compound often used in the metalworking and construction industries. thermite can be produced from aluminum and iron oxide according to this reaction:_______.

Answers

thermite can be produced from aluminum and iron oxide according to redox reaction.

Redox reaction is defined as the the reaction in which one substance get oxidised and other one is reduced. In other words, Oxidation reduction reaction is called redox reaction.

Oxidation is termed as gain of electron and Reduction is termed as lose of electron.

Thermite is a mixture of an oxide of one metal and a powder of another metal.

Aluminium is usually used as a metal that basically decreases the oxide of the metal.

The thermite contains a mass ratio of ferric oxide and aluminium of 3:1.

It is used to weld broken iron pieces thermally. The reduction of aluminium ferric oxide is extremely exothermic, so the iron produced would be in the molten state.

Fe2O3+2Al→Al2O3+2Fe+heat

Thus, redox reaction of aluminum and ferrous oxide produce thermite.
