What is the maximum mass in grams of NH3 that can be produced by the reaction of of 2.5 g N2 with 2.5 g of H2 via the equation below?N2 (g) + 3 H2 (g) → 2 NH3 (g)

Answers

Answer 1

Answer:

Answer: The mass of $NH_3$ produced is, 3.03 grams.

Explanation : Given,

Mass of $N_2$ = 2.5 g

Mass of $H_2$ = 2.5 g

Molar mass of $N_2$ = 28 g/mol

Molar mass of $H_2$ = 2 g/mol

First we have to calculate the moles of $N_2$ and $H_2$ .

$\text{Moles of }N_2=\frac{\text{Given mass }N_2}{\text{Molar mass }N_2}=(2.5g)/(28g/mol)=0.089mol$

and,

$\text{Moles of }H_2=\frac{\text{Given mass }H_2}{\text{Molar mass }H_2}=(2.5g)/(2g/mol)=1.25mol$

Now we have to calculate the limiting and excess reagent.

The balanced chemical equation is:

$N_2(g)+3H_2(g)\rightarrow 2NH_3(g)$

From the balanced reaction we conclude that

As, 1 mole of $N_2$ react with 3 mole of $H_2$

So, 0.089 moles of $N_2$ react with $0.089* 3=0.267$ moles of $H_2$

From this we conclude that, $H_2$ is an excess reagent because the given moles are greater than the required moles and $N_2$ is a limiting reagent and it limits the formation of product.

Now we have to calculate the moles of $NH_3$

From the reaction, we conclude that

As, 1 mole of $N_2$ react to give 2 mole of $NH_3$

So, 0.089 mole of $N_2$ react to give $0.089* 2=0.178$ mole of $NH_3$

Now we have to calculate the mass of $NH_3$

$\text{ Mass of }NH_3=\text{ Moles of }NH_3* \text{ Molar mass of }NH_3$

Molar mass of $NH_3$ = 17 g/mole

$\text{ Mass of }NH_3=(0.178moles)* (17g/mole)=3.03g$

Therefore, the mass of $NH_3$ produced is, 3.03 grams.

What mass of CO2 (in kilograms) does the combustion of a 16-gallon tank of gasoline release into the atmosphere? Assume the gasoline is pure octane (C8H18) and that it has a density of 0.70 g/mL.Express your answer in kilograms to two significant figures.

Answers

Mass of CO₂ = 1.3 x 10⁵ kg

Further explanation

A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.

Reaction

2C₈H₁₈ + 25O₂⇒ 16CO₂ + 18H₂O

16 gallon = 60566,6 ml

mass C₈H₁₈ :

$\tt mass=\rho* V\n\nmass=0.7* 60566.6=42396.62~g$

mol C₈H₁₈ :

$\tt MW=114.232~g/mol\n\nmol=(42396.62)/(114.232)=371.145$

mol CO₂ :

$\tt (16)/(2)* 371.145=2969.159$

mass CO₂ :

$\tt =2969.159* 44(MW~CO_2)=130642.996~g=1.3* 10^5~kg$

Calculate the percent mass per volume, % (m/v), of a dextrose solution containing 7.00 g of dextrose in 2.00×102 mL of solution. Note that mass is not technically the same as weight, but the abbreviation % (w/v) is often used interchangeably with % (m/v).

Answers

Answer:

The mass per unit volume percentage is equal to 3.43%

Explanation:

given

mass=7 grams

volume = 2 * 102 ml = 204ml

The percentage mass per volume is given by

%(m/v) = w grams of solute * 100 / Volume of solution in ml

= $(7)/(204)*100$

= 3.43%

Final answer:

The percent mass/volume (% m/v) for a solution containing 7.00 g of dextrose in 2.00×102 mL of solution is calculated as (7.00 g / 2.00×102 mL) * 100 = 3.47%, so the dextrose solution is 3.47% m/v.

Explanation:

The percent mass/volume (% m/v) is a way of expressing the concentration of a solute in a solution. It is calculated as the mass of the solute divided by the volume of the solution, multiplied by 100%. In this case, to calculate the % m/v for a solution that contains 7.00 g of dextrose in 2.00×102 mL of solution, you would use the following equation:

% m/v = (mass of solute / volume of solution) * 100

Substituting the given values into this equation, you get:

% m/v = (7.00 g / 2.00×102 mL) * 100 = 3.47%

Therefore, the dextrose solution is 3.47% m/v.

what is electromagnetic force ?

An electromagnetic force is one of the four fundamental forces a combination of both electrical and magnetic forces and this force is act up on the charged particles .

It is inversely proportional to the inverse square of the distance between particles, electromagnetic force can be attractive or repulsive shows infinite range and this force holds atoms together in molecules.

This force can be produced by electromagnetic fields, electrostatic field, and magnetostatic field which affects all of the universal objects due to its infinite range.

This force causes electric and magnetic effects like repulsion between like electrical charges or the interaction of bar magnets, it is weaker than the strong force.
