Answer:

Mass of C₂H₄N₂ produced = 3.64 g

Explanation:

The balanced chemical equation for the reaction is given below:

3CH₄ (g) + 5CO₂ (g) + 8NH₃ (g) → 4C₂H₄N₂ (g) + 10H₂O (g)

From the equation, 3 moles of CH₄ reacts with 5 moles of CO₂ and 8 moles of NH₃ to produce 4 moles of C₂H₄N₂ and 10 moles of H₂O

Molar masses of the compounds are given below below:

CH₄ = 16 g/mol; CO₂ = 44 g/mol; NH3 = 17 g/mol; C₂H₄N₂ = 56 g/mol; H₂O g/mol

Comparing the mole ratios of the reacting masses;

CH₄ = 1.65/16 = 0.103

CO₂ = 13.5/44 = 0.307

NH₃ = 2.21/17 = 0.130

converting to whole number ratios by dividing with the smallest ratio

CH₄ = 0.103/0.103 = 1

CO₂ = 0.307/0.103 = 3

NH₃ = 0.130/0.103 = 1.3

Multiplying through with 5

CH₄ = 1 × 5 = 5

CO₂ = 3 × 5 = 15

NH₃ = 1.3 × 5 = 6.5

Therefore, the limiting reactant is NH₃

8 × 17 g (136 g) of NH₃ reacts to produce 4 × 56 g (224 g) of C₂H₄N₂

Therefore, 2.21 g of NH₃ will produce (2.21 × 224)/136 g of C₂H₄N₂ = 3.64 g of C₂H₄N₂

Mass of C₂H₄N₂ produced = 3.64 g

swat32

Answer:

The correct answer is "D".

Explanation:

The synthesis consists of extracting the most important data from a text or any source of information. To be able to synthesize it is necessary to read, understand and interpret the message or arguments presented. Once these factors have been extracted, they are brought together to form a coherent text that in a few words explains the original text.

Have a nice day!

A task

B communication

C skill

<u>Answer:</u>

Throughout your job search, you’ll find that  education   is closely related to the career of your choosing. It’s important to take the time to find out what to expect now, so you can start developing the  skill  that you need to excel in that career.

<u>Explanation:</u>

At the time of attending our interview, we find that the question raised from an interviewer related to the choosing of the field and from our educational background. So, it clearly based on what we learn via our education and how we can get connected to the selected field but not based on our salary or an economy.

Similarly, it is essential to make a note about the requirement from the chosen field and have to prepare our skill accordingly. It means that required to develop the knowledge related to our selective field and should be presented in a connected way in front of an interviewer.
