Hello!
Take for example the heating of water.
When heating liquid water from room temperature (25 °C) to the boiling point (100 °C), adding heat results in a direct increase in the temperature. This kind of heat is called sensible heat, because we can sense the effect of the added energy.
But when you reach 100 °C, there is a phase change from liquid to vapour, and the added heat is used to produce the phase change, and no increase in temperature is observed, only the phase change. This kind of heat is called latent heat.
Have a nice day!
In any balanced
chemical reaction, the elements or compounds which are located in the left hand
side of the arrow is the reactants while those that are location on the right
hand side are the products, therefore the product here is:

Answer: 1.31
Explanation:
No.of moles = given no.of atoms/Avagadro number
= 7.91×10^23 / 6.022 x 10^23
= 1.31
therefore, no.of moles = 1.31
Hope it helped u,
