answer type questions
ow do metals and non-metals react with acids? Write and expla
quation for the reaction of magnesium with sulphuric acid and
drochloric acid​

Answer 1

Answer:

1)You must have found that non- metals generally do not react with acids but metals react with acids and produce hydrogen gas that burns with a 'pop' sound. You must have noticed that copper does not react with dilute hydrochloric acid even on heating but it reacts with sulphuric acid.

2) Magnesium combined with sulfuric acid produces magnesium sulfate and hydrogen gas. MgCl2 + H2SO4 ---> MgSO4 + 2HCl.Magnesium and hydrochloric acid react according to the chemical equation: Mg + 2HCl => MgCl2 + H2.

Answer 2

Answer:

Metals react with acids and produce metal salts and hydrogen gas. Generally, non-metals do not react with acids. Some metals react with bases to produce hydrogen gas. More reactive metals displace less reactive metals from their compounds in aqueous solutions

Explanation:

Magnesium combined with sulfuric acid produces magnesium sulfate and hydrogen gas.

Reactants:

The symbol for magnesium is

Mg

.

The formula for sulfuric acid is

H2SO4

Products:

Magnesium forms a

2+ ion: Mg2+

The sulfate ion has a charge of

2− : SO2−4

The charges balance and thus the formula for

magnesum sulfate is

MgSO4

Hydrogen gas is diatomic:

H2

Mg+H2SO4→MgSO4+H2

The reaction is balanced as written. Each side has one magnesium atom, two hydrogen atoms and one sulfate ion
