Since gasses weigh nothing when they are produced in a reaction they do not have to be accounted for.

Chemistry

Cerrena [4.2K]2 years ago
8 0

Answer:

No

Explanation:

You can not have a reaction that produces "no mass". This breaks the law of conservation of mass. When gasses are produced, they will have a specific amount of mass associated with them which means they will have a weight. They will have to be accounted for

After a reaction, a new compound contains 0.73 g Mg and 0.28 g N. What is the empirical formula of this compound?
FromTheMoon [43]

Answer:

Mg₃N₂

Explanation:

The empirical formula of a chemical compound is defined as the simplest positive integer ratio of atoms present in a compound. Using molecular mass of Mg (24,305g/mol) and mass of nitrogen (14,006g/mol), moles of each element are:

0,73g × (1mol / 24,305g) = 0,03 moles of Mg

0,28g × (1mol / 14,006g) = 0,02 moles of N

Dividing each value in 0,01 to obtain natural numbers:

0,03 moles of Mg / 0,01 = 3

0,02 moles of N / 0,01 = 2.

Thus, empirical formula is: <em>Mg₃N₂</em>
