what is an empirical formulaWhat is the percent composition by mass of nitrogen in (NH4)2CO3 (gram-formula mass = 96.0 g/mol)?
Margarita [4]

Answer:

Percentage composition = 14.583%

Explanation:

In chemistry, the emprical formular of a compound is the simplest formular a compound can have. It shows the simplest ratio in which the elements are combined in the compound.

Percentage composition by mass of Nitrogen

Nitrogen = 14g/mol

In one mole of the compound;

Mass of Nitrogen = 1 mol * 14g/mol = 14g

Mass of compound = 1 mol * 96.0 g/mol = 96

Percentage composition of Nitrogen = (Mass of Nitrogen /  Mass of compound) * 100

percentage composition = 14/96   * 100

Percentage composition = 0.14583 * 100

Percentage composition = 14.583%

To break a chemical bond, particles need to collide with a certain amount of ____?
Harrizon [31]

Explanation:

To break a chemical bond, it is required that particles must have certain amount of energy so that when they can collide with each other due to this energy.

Therefore, there will exist a certain amount of force between the particles which will help in breaking the chemical bond.

This energy due to the motion of particles is known as kinetic energy.

Thus, we can conclude that to break a chemical bond, particles need to collide with a certain amount of kinetic energy.
