N2+3H2—> 2NH3 What volume of NH3 at STP is produced if 25.0g of N2 is reacted with an excess of H2 ?
Butoxors [25]

Answer:

The answer to your question is 40 L of NH₃

Explanation:

Data

Volume of NH₃ = x

mass of N₂ = 25 g

mass of H₂ = excess

Balanced chemical reaction

                     N₂  +  3H₂   ⇒  2NH₃

Process

1.- Find the molar mass of N₂ and NH₃

N₂ = 14 x 2 = 28g

2NH₃ = 2[ 14 + 3] = 34 g

2.- Write a proportion to solve this problem

                    28 g of N₂ --------------- 34 g of NH₃

                     25 g of N₂ -------------   x

                     x = (25 x 34)/28

                     x = 30.36 g of NH₃

3.- Calculate the volume of NH₃

                     17 g of NH₃ -------------- 22.4 L

                     30.36 g of NH₃ --------  x

                     x = (30.36 x 22.4) / 17

                     x = 40 L

Write the resonance forms of ozone, O3, the component of the upper atmosphere that protects the Earth from ultraviolet radiation
aleksklad [387]

Answer:

The resonance forms of O3 are attached as an image.

Explanation:

A compound with different contributing structures comes together and forms a resonating or intermediate structure that best describes the properties of that compound.

The given compound is ozone, having the chemical formula  

O3 = 6 electrons * 3 = 18 electrons

O → prefers to have a complete their octet

The bonding electrons and lone pair electrons are radical electrons that are present on the oxygen atoms tend to delocalize and results in various resonating forms of O3.

An automobile gasoline tank holds 23 kg of gasoline. When the gasoline burns, 86 kg of oxygen is consumed, and carbon dioxide an
ira [324]

Question:

What is the total combined mass of carbon dioxide and water that is produced?

Answer:

<u><em>109 kg</em></u>

Explanation:

When 23 kg of gasoline burns by consuming 86 kg oxygen, they produce carbon dioxide and water. To find the total combined mass of carbon dioxide and water, we will use mass conversation law.

According to mass conversation law, the mass of the product is equal to the mass of reagent.

Mass of reagent = Mass of product

In this reaction,

Gasoline + O2 → CO2 + H2O

23 kg + 86 kg → ?

23 kg + 86 kg =  109 kg

Combined mass of carbon dioxide and water will be 109 kg.
