All acids, when dissolved in water, react in similar ways with metals, metal oxides and metal carbonates. Why do acids have these similar properties?
Acids are compounds with hydrogen in their chemical formula.
Hydrogen atoms in an acid can be replaced by metal atoms to form a salt.
Acids dissolve in water to produce a solution containing ions.
Acids produce hydrogen ions when they dissolve in water.
What is made when an acid and metal carbonate react?
Carbon dioxide, water and a salt
A salt, hydrogen and water
Salt and water
Oxygen, salt and water
What is made when an acid and base react?
Carbon dioxide and a salt.
Salt and hydrogen.
Salt and water.
Oxygen and salt.
Barium metal is mixed with nitric acid. The products of the reaction are:
hydrogen gas and nitric acid.
hydrogen gas and barium nitrate.
carbon dioxide and barium nitrate.
barium nitrate and water.

decomposition reaction.
synthesis reaction.
precipitation reaction.
acid-carbonate reaction.
A gas is produced by a chemical reaction. The gas does not turn limewater cloudy, and when a flame is brought near the gas, it ignites. The gas is:
carbon dioxide.
hydrogen.
oxygen.
nitrogen.
