Chemical change is where there is breaking and making of bonds

Physical change is where there is change in states of matter

A physical change is classified as a change that does not affect the identity of the substance. Otherwise, that would be a chemical change. From the picture above, you will know that it is a chemical change if the colored circles combined with a different color. You will know if it's a physical change if there is only separation of the same colors. The answers are shown in the picture attached.

How many grams are in 4.07x10^15 molecules of calcium hydroxide
maksim [4K]

There are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.

HOW TO CALCULATE MASS:

The mass of a substance can be calculated by multiplying the number of moles in the substance by its molecular mass.

However, given that the number of molecules in calcium hydroxide is 4.07 x 10¹⁵molecules, we need to calculate the number of moles in Ca(OH)2 as follows:

no. of moles of Ca(OH)2 = 4.07 x 10¹⁵ ÷ 6.02 × 10²³

no. of moles = 0.676 × 10-⁸

no. of moles = 6.76 × 10-⁹ moles.

Molar mass of Ca(OH)2 = 74.093 g/mol

Mass of Ca(OH)2 = 74.093 × 6.76 × 10-⁹ moles

Mass = 5.01 × 10-⁷grams.

Therefore, there are 5.01 × 10-⁷grams in 4.07 x 10¹⁵molecules of calcium hydroxide.
