Lab Review - Single Replacement Reactions

Front

What is a single replacement reaction?

Back

A single replacement reaction is a type of chemical reaction where one element replaces another element in a compound.

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where A is a more reactive element that displaces B from the compound BC.

Front

What determines whether a single replacement reaction will occur?

Back

The reactivity of the elements involved; a more reactive element can replace a less reactive element.

Front

What is the reactivity series?

Back

A list of metals arranged in order of decreasing reactivity, used to predict the outcomes of single replacement reactions.

Front

What are the products of the reaction Mg + CuCl₂?

Back

Cu + MgCl₂.

Front

How do you balance a chemical equation?

Back

By ensuring that the number of atoms of each element is the same on both sides of the equation.

Front

What is the balanced equation for the reaction of tin (IV) oxide with hydrogen?

Back

SnO₂ + 2H₂ → Sn + 2H₂O.

Front

What happens when a less reactive metal is placed in a solution of a more reactive metal's salt?

Back

No reaction will occur.

Front

In the reaction Au + HCl, if hydrogen is more reactive than gold, what is the outcome?

Back

No reaction will occur.

Front

What is the outcome when cobalt metal is mixed with nickel nitrate?

Back

Cobalt will react because it is more reactive than nickel.
