Consider the reaction N2(g) + 3H2(g) → 2NH3(g) Suppose that at a particular moment during the reaction, molecular hydrogen is re
rosijanka [135]

Answer:

The solution to the question is as follows

(a) The rate of ammonia formation = 0.061 M/s

(b) the rate of N₂ consumption = 0.0303 M/s

Explanation:

(a) To solve the question we note that the reaction consists of one mole of N₂ combining with three moles of H₂ to form 2 moles of NH₃

N₂(g) + 3H₂(g) → 2NH₃(g)

The rate of reaction of molecular hydrogen = 0.091 M/s, hence we have

3 moles of H₂ reacts to form 2 moles of NH₃, therefore

0.091 M of H₂ will react to form 2/3 × 0.091 M or 0.061 M of NH₃

Hence the rate of ammonia formation is 0.061 M/s

(b) From the reaction equation we have 3 moles of H₂ and one mole of N₂ being consumed at the same time hence

0.091 M of H₂ is consumed simultaneously with 1/3 × 0.091 M or 0.0303 M of N₂

Therefore the rate of consumption of N₂ = 0.0303 M/s

FromTheMoon [43]

A granola bar states that it is 17.0% protein; each granola bar has a mass of 35.0 grams 5 bars need to consume to eat 29.7 grams of protein.

<h3 /><h3>What is protein?</h3>

Protein is a source of energy by which all humans and animals can do their work as it provide energy to the cells of the human and animal and important too.

A granola bar is source of protein contain 17.0% protein 35.0 grams each bar contain 5.2 gram protein 29.7 grams protein is in 5 bars of granola bar.

Therefore, granola bar states that it is 17.0% protein,each granola bar has a mass of 35.0 grams 5 bars need to consume to eat 29.7 grams of protein.
