Concept explainers
Interpretation : The part of a chemical equation that allows us to determine the amount of product obtained from a known amount of reactants is to be stated.
Concept Introduction : The stoichiometric number is defined as the digit that is written in front of any molecule, atom or ion that is taking part in a
Limiting reagent is the amount of substance that gets totally consumed in reaction.
Answer to Problem 1RQ
The
Explanation of Solution
The stoichiometric coefficient in front of reactants determines how much amount of reactant has taken part in chemical reaction. It also helps in determining the limiting reagent in reaction and its amount in a chemical reaction. It is also known that limiting reagent specifies the amount of product produced in a chemical reaction. Therefore, stoichiometric coefficient tells us about the amount of product obtained.
The stoichiometric coefficient determines the amount of product formed from the known amount of reactants.

- Please correct answer and don't used hand raitingarrow_forward142. A mixture of H2(g) and N2(g) has a density of 0.216 g/liter at 300 K and 500 torr. What is the mole fraction composition of the mixture?arrow_forwardOne liter of N2(g) at 2.1 bar and two liters of Ar(g) at 3.4 bar are mixed in a 4.0 liter flask to form an ideal gas mixture. Calculate the value of the final pressure of the mixture if the initial and final temperature of the gases are the same. Repeat this calculation if the initial temperature of the N2(g) and Ar(g) are 304 K and 402 K, respectively, and the final temperature of the mixture is 377 K.arrow_forward
