Mass is always conserved in a physical change. Energy may be released or absorbed when a substance changes from one physical state to another. In a chemical change, a chemical reaction yields a completely new substance. A substance's particles are changed during a chemical reaction.

Ammonia is produced from the reaction of nitrogen and hydrogen according to the following balanced equation: N2 1 g 2 1 3H2 1 g
bekas [8.4K]

Answer:

Mass of NH3 produced = 1217 g or 1.217*10^3 g

Explanation:

<u>Given:</u>

Mass of N2 = 1.003*10^3 g

Mass of H2 = 5.003*10^2 g

<u>To determine:</u>

Maximum mass of NH3 that can be produced when the given amounts of N2 and H2 combine

<u>Calculation:</u>

The chemical reaction corresponding to the production of ammonia is:

N2(g)+3H2(g)\rightarrow 2NH3(g)

Based on the reaction stoichiometry:

1 mole of N2 combines with 3 moles of H2 to form 2 moles of NH3

moles\ of\ N2 = \frac{Mass\ N2}{Molar\ mass N2} = \frac{1.003*10^{3}g }{28g/mol} =35.8\ moles

moles\ of\ H2 = \frac{Mass\ H2}{Molar\ mass H2} = \frac{5.003*10^{2}g }{2g/mol} =250\ moles

Since the moles of N2 is less than that of H2, the limiting reagent will be N2 which would in turn determine the amount of NH3 formed.

Based on the reaction stoichiometry the N2 : NH3 ratio = 1:2

Therefore,

moles\ of\ NH3\ produced = 2*35.8 = 71.6\ moles\\\\Mass\ of\ NH3\ produced = moles*molar mass = 71.6\ moles*17\ g/mol = 1217 g

Simora [160]

Answers:

Most of the world’s energy comes from what three sources?

Oil, coal, and gas.

These energy sources are called <u>fossil</u> fuels and they are <u>non-renewable</u> resources.

Fuel type: oil

How it's formed: from the remains of ancient marine organisms

Its uses: transportation, industrial power, heating and lighting, lubricants, petrochemical industry, and use of by-products

Fule type: coal

How it's formed: when dead plant matter decays into peat and is converted into coal by the heat and pressure of deep burial

Its uses: electricity generation, metal production, cement production, chemical production, gasification, and other industrial uses

Fuel type: gas

How it's formed: decomposed organic matter mixed with mud, silt, and sand on the seafloor

Its uses: heating & cooling buildings, cooking foods, fueling vehicles, and electricity generation
