If 175.0g of nitrogen is reacted with 250.0g of hydrogen, what is the theoretical yield of the reaction? What is the excess reactant? What is the limiting reactant? Show your work.

Nitrogen gas is the limiting reactant

Hydrogen gas is the excess reactant

The theoretical yield is 425 g of ammonia

Explanation:

Equation of reaction: 3H2 + N2 ---> 2NH3

From the equation of reaction, 3 moles of hydrogen gas reacts with 1 mole of nitrogen to produce 2 moles of ammonia gas.

Molar mass of hydrogen gas = 2.0 g

Molar mass of nitrogen gas = 14.0 g

Molar mass of ammonia gas = 17.0 g

Number of moles of hydrogen gas in 250 g = 250/2 = 125 moles

Number of moles of nitrogen gas in 175 g = 175/14 = 12.5 moles

Mole ratio of Hydrogen to Oxygen = 125/12.5 = 10 : 1

Therefore, nitrogen gas is the limiting reactant.

Hydrogen gas is the excess reactant

14 g of nitrogen gas produces 17 × 2 g of ammonia = 34 g of ammonia

175 g will produce (34 × 175)/14 = 425 g of ammonia

Therefore the theoretical yield is 425 g of ammonia

chemical digestion occurs in the stomach were hcl and pepsin forms chyme, the mouth in which salivary amylase breaks down starch to form bolus, and the small intestine specifically the duodenum.

the answer is b because, investigating whether another species of moth also drinks tears might be interesting, but it would not directly explain why this species of moth does.

to explain why this species of moth drinks tears, the scientist could ask: "what nutrients that moths need are in elephant tears? "

the scientist could experiment with moth repellent or oter ways to keep the moths away, but that would not answer his original question.
