An experiment is carried out to produce hydrogen gas. hydrochloric acid is poured into a glass, and magnesium is added to the acid. the reaction produces a soluble salt and hydrogen gas. 2.1 write a balanced equation for the reaction. 2.2 give the name of the soluble salt. 2.3 has a physical or chemical change taken place? 2.4 2 moles of hydrogen is produced. how many moles of acid reacted?

Explanation:

1) A balanced equation for the reaction.

2) The name of the soluble slat produced by reaction between magnesium and hydrochloric acid is magnesium chloride.

Magnesium chloride =

3)Yes, chemical change has been taking.

This is because rearrangement of atom is taking place which resulted in formation of hydrogen gas amd magnesium chloride.

4) Moles of hydrogen gas produced = 2 mole

According to reaction, 1 mole of hydrogen gas is obtained from 2 moles of HCl.

Then 2 moles of hydrogen gas will be obtained form:

of HCl

4 moles of acid has reacted.

it should have an internal chamber and two thermometers sticking out of the top. the internal chamber will also be closed off from the outside.
