Most plastics are made from oil or natural gas. One step in making plastics from these resources is called cracking. Cracking is

a process that breaks down bigger molecules into smaller ones. In one cracking reaction, ethane breaks down to become ethylene and hydrogen. During this process, thermal energy is absorbed from the surroundings and converted to chemical energy.

A 1.50-g sample of hydrated copper(II) sulfate was heated carefully until it had changed completely to anhydrous copper(II) sulf
ElenaW [278]

Answer:

X = 5

Explanation:

Total mass here is 1.5g. Now after heating we have a mass of 0.957g Cu. This means heating had caused a loss of 1.5 - 0.957 = 0.543g of water.

Now, we will try to convert this into moles. This can be done by dividing the respective masses by the molar masses. While the mass of water is 18g/mol, the molar mass of CuSO4 is 160g/mol.

The division of the respective masses by the molar masses is thus:

CuSO4 = 0.957/160 = 0.006 moles

H2O = 0.543/18 = 0.03 moles

The ratios of the moles is thus: 0.03/0.006 = 5

Hence, the number of molecules of water of crystallization is 5

This means x = 5

What indicates that a chemical change has occurred?
ki77a [65]
Many things could indicate that a chemical change has occurred. The release of a gas, or bubbling, etc. Just be careful not to mix it up with physical changes. A chemical change means that the chemical structure is different. You can reverse a physical change, but you cannot reverse a chemical reaction.
