How many grams of ammonia (NH3) can be produced by the synthesis of excess hydrogen gas (H2) and 253.8 grams of nitrogen gas (N2) in a synthesis reaction?

Answers

Answer:

308.2 g of NH₃.

Explanation:

We'll begin by writing the balanced equation for the reaction. This is illustrated below:

3H₂ + N₂ —> 2NH₃

Next, we shall determine the mass of N₂ that reacted and the mass of NH₃ produced from the balanced equation. This can be obtained as follow:

Molar mass of N₂ = 2 × 14 = 28 g/mol

Mass of N₂ from the balanced equation = 1 × 28 = 28 g

Molar mass of NH₃ = 14 + (3×1)

= 14 + 3 = 17 g/mol

Mass of NH₃ from the balanced equation = 2 × 17 = 34 g

Summary:

From the balanced equation above,

28 g of N₂ reacted to produce 34 g of NH₃.

Finally, we shall determine the mass of NH₃ produced by the reaction of 253.8 g of N₂. This can be obtained as illustrated below:

From the balanced equation above,

28 g of N₂ reacted to produce 34 g of NH₃.

Therefore, 253.8 g of N₂ will react to produce = (253.8 × 34)/28 = 308.2 g of NH₃.

Thus, 308.2 g of NH₃ were obtained from the reaction.

Fe2O3 (s) + CO (g) -> Fe(s) + CO2 (g) (unbalanced)
1.Calculate the number of grams of CO that can react with 0.150kg of Fe2O3
2. Calculate the number of grams of Fe and the number of grams of CO2 formed
when 0.150 kg of Fe2O3 reacts

Answers

Answer:

1. 78.9g of CO

2. 104.9g Fe and 124.0g CO2

Explanation:

Based on the balanced reaction:

Fe2O3 (s) + 3CO (g) -> 2Fe(s) + 3CO2 (g)

1 mole of Fe2O3 reacts with 3 moles of CO to produce 2 moles of Fe and 3 of CO2

1. The moles of 0.150kg = 150g of Fe2O3 -Molar mass: are:

150g * (1mol / 159.69g) = 0.9393 moles Fe2O3

Moles CO:

0.9393 moles Fe2O3 * (3mol CO / 1mol Fe2O3) = 2.818 moles CO

Mass CO -Molar mass: 28.01g/mol-:

2.818 moles CO * (28.01g/mol) = 78.9g of CO

2. The moles of Fe produced are:

0.9393 moles Fe2O3 * (2mol Fe / 1mol Fe2O3) = 1.8786 moles Fe

Mass Fe -Molar mass: 55.845g/mol-:

1.8786 moles Fe * (55.845g/mol) = 104.9g Fe

The moles of CO2 produced are:

0.9393 moles Fe2O3 * (3mol CO2 / 1mol Fe2O3) = 2.818moles CO2

Mass CO2 -Molar mass: 44.01g/mol-:

2.818moles CO2 * (44.01g/mol) = 124.0g CO2

Explanation:

The gas planets are Jupiter, Saturn, Uranus and Neptune.

Answer:

A gas giant is a large planet composed mostly of gases, such as hydrogen and helium, with a relatively small rocky core. The gas giants of our solar system are Jupiter, Saturn, Uranus and Neptune. These four large planets, also called jovian planets after Jupiter, reside in the outer part of the solar system past the orbits of Mars and the asteroid belt. Jupiter and Saturn are substantially larger than Uranus and Neptune, and each pair of planets has a somewhat different composition.Although there are only four large planets in our solar system, astronomers have discovered thousands outside of it, particularly using NASA's Kepler Space Telescope. These exoplanets (as they are called) are being examined to learnmore about how our solar system came to be.

How many Carbon Atoms are there on the PRODUCT SIDE

Answers

Answer: There are 6 carbon atoms on the product side.

Explanation:

The given reaction equation is as follows.

[tex]6CO_{2} + 6H_{2}O \rightarrow C_{6}H_{12}O_{6} + 6O_{2}[/tex]

Species present on the left side of an arrow in a chemical equation depicts the reactants.

Species present on the right side of an arrow in a chemical equation depicts the products.

Hence, products in the given reaction equation are [tex]C_{6}H_{12}O_{6}[/tex] and [tex]6O_{2}[/tex].

Therefore, there are 6 carbon atoms present on the product side.

Thus, we can conclude that there are 6 carbon atoms on the product side.

Answers

Answer:

143.9 mL is the new volume for the gas.

Explanation:

Let's apply one of the gases law to solve this problem:

Boyle's law states that the product of pressure and volume remains constant when the T° is not modified.

P₁ . V₁ = P₂ . V₂

Be careful because we have T° in mmHg. We need to convert to atm:

750.12 mmHg . 1 atm / 760 mmHg = 0.987 atm

We replace data:

150 mL . 0.947 atm = 0.987 atm . V₂

V₂ = (150 mL . 0.947 atm) / 0.987 atm

V₂ = 143.9 mL

This term P . V comes from the Ideal Gases Law

P . V = n . R . T

The theoretical yield of NH3 is 945 grams. You conducted the experiment and only produced 598 grams.

Answers

Answer:

Given theoretical yield of NH3 is 945g.

The actual yield is 598g.

What is the %yield?

Explanation:

%yield of a chemical reaction can be calculated by using the formula:

[tex]%yield=\frac{actual yield}{theoretical yield} * 100[/tex][tex]\frac{actual yield}{theoretical yield} * 100[/tex]

Substitute the given values in this formula to get the %yield.
