The first set of questions are based on the “reaction” illustrated as: 2g + 1c + 1m --> 1s
if you are given 12 graham crackers, how many chocolate bars and marshmallows would you need to completely use all the graham crackers? show your calculations.
how many s’mores can you make? show your calculations.

6 Chocolate bars and c marshmallows would be needed to completely use all the 12 graham crackers.

We can be able to make 6 s'mores.

Explanation:

2G + 1C + 1M → S

According to reaction , 2 graham crackers along with 1 chocolate bar and 1 marshmallow gives 1 s'more.

Then for 12 graham crackers will combine with:

Then for 12 graham crackers will combine with:

Then 12 graham crackers will give:

We can be able to make 6 s'mores.

the formula mass of a molecule or a compound is the sum of the atomic weights of the atoms in its empirical formula

(that's what i know about formula mass)

the transfer of heat by electromagnetic radiation is called thermal radiation . it is usually carried out by electromagnetic waves in an energy range just below the visible spectrum, which is the infrared range.

so the answer would be radiation.
