Answer:

$\boxed {\boxed {\sf \frac{ 4 \ mol \ A}{3 \ mol \ D}}}$

Explanation:

The mole ratio in a balanced equation tells us the number of moles of each reactant needed and how many moles of product will be made.

We are asked to find the mole ratio between A and D for this reaction.

$4A + 5B \rightarrow 2C + 3D$

The mole ratio is found by comparing the coefficients, which are the numbers in front of the formulas.

A has a coefficient of 4 and D has a coefficient of 3.

Therefore, the ratio between A and D is:

A gas is composed of a large number of particles called molecules (whether monatomic or polyatomic) that are in constant random motion.

Because the distance between gas molecules is much greater than the size of the molecules, the volume of the molecules is negligible.

Intermolecular interactions, whether repulsive or attractive, are so weak that they are also negligible.

Gas molecules collide with one another and with the walls of the container, but these collisions are perfectly elastic; that is, they do not change the average kinetic energy of the molecules.

The average kinetic energy of the molecules of any gas depends on only the temperature, and at a given temperature, all gaseous molecules have exactly the same average kinetic energy.
