Which of the following can be calculated from the mass of the reactants used in a chemical reaction?Amount of limiting reactant used in a reactionActual yield of productsAmount of excess reactant from a reactionTheoretical yield of products

Explanation:

There are some options that are correct.

1) Amount of limiting reactant used in a reaction.

It can be calculated from the quantity of the reactants.

2) Amount of excess reactant from a reaction

It can be also calculated from the quantity of the reactants.

3) Theoretical yield of products

Amount of limiting reactant used in a reaction

Amount of excess reactant from a reaction

Theoretical yield of products

answer: the rate of diffusion increases with increase in temperature.

increase in temperature, increases the molecular/particles speed (kinetic energy. diffusion means movement of particles through the material.

generally, the heavier the particle the more it interacts with the environment and more the temperature matters. so higher temperature results in higher diffusion.
