The production of a gas is different because unlike the heating curve, there was no heat applied to this experiment, and the experiment was a chemical reaction.

<h3>What is a Heating curve?</h3>

This shows the relationship between the temperature of the heating system and the air temperature in the outer environment.

The chemical reaction emitted heat as against the other which involved heat application which is why water formation in this curve was different.

) How many moles are there in 2.00 x 10^19 molecules of calcium phosphate?
Tamiku [17]

Answer:

\huge 3.322 \times  {10}^{ - 5}  \:  \: moles  \\

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L} \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{2.00 \times  {10}^{19} }{6.02 \times  {10}^{23} }  \\  \\  = 3.322 \times  {10}^{ - 5}  \:  \: moles

Hope this helps you
