Front

What is the activity series in chemistry?

Back

The activity series is a list of metals arranged in order of decreasing reactivity. It helps predict whether a reaction will occur between metals and compounds.

Front

Will gold (Au) react with hydrochloric acid (HCl)?

Back

No, gold is less reactive than hydrogen and does not displace it from HCl.

Front

What is a balanced chemical equation?

Back

A balanced chemical equation has equal numbers of each type of atom on both sides of the equation, following the law of conservation of mass.

Front

What is the correct ratio of reactants and products in the reaction CO + Fe2O3 → Fe + CO2?

Back

3 CO + 1 Fe2O3 → 2 Fe + 3 CO2.

Front

What is a synthesis reaction?

Back

A synthesis reaction is a type of chemical reaction where two or more simple substances combine to form a more complex product.

Front

Provide an example of a synthesis reaction.

Back

MgO + CO2 → MgCO3.

Front

What is a double replacement reaction?

Back

A double replacement reaction is a type of chemical reaction where two compounds exchange ions or bonds to form two new compounds.

Front

Complete the balanced equation for the double replacement reaction: 3 NaOH + Fe(NO3)3 → ?

Back

3 NaNO3 + Fe(OH)3.

Front

What type of reaction is CO2 + H2O → H2CO3?

Back

Synthesis reaction.

Front

What is the definition of a decomposition reaction?

Back

A decomposition reaction is a type of chemical reaction where a single compound breaks down into two or more simpler products.
