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

How can you predict if a double replacement reaction will occur?

Back

You can predict if a double replacement reaction will occur by using a solubility chart to determine if any of the products are insoluble.

What is the activity series of metals?

Back

The activity series of metals is a list of metals arranged in order of decreasing reactivity, which helps predict whether a metal will displace another in a reaction.

Which metal is more reactive: Ca or Sr?

Back

Sr (Strontium) is more reactive than Ca (Calcium) according to the activity series.

What products are formed when sodium reacts with water?

Back

When sodium reacts with water, sodium hydroxide (NaOH) and hydrogen gas (H2) are produced.

What is the general reaction for a metal reacting with an acid?

Back

A metal reacting with an acid typically produces a salt and hydrogen gas.

Front

What are the products of the reaction between copper and silver nitrate?

Back

The products of the reaction between copper (Cu) and silver nitrate (AgNO3) are copper(II) nitrate (Cu(NO3)2) and silver (Ag).

What happens during the thermal decomposition of magnesium carbonate (MgCO3)?

Back

During the thermal decomposition of magnesium carbonate (MgCO3), it breaks down into magnesium oxide (MgO) and carbon dioxide (CO2).

Front

What is a solubility chart used for?

Back

A solubility chart is used to determine the solubility of various compounds in water, helping to predict whether a precipitate will form in a reaction.

Front

What is the significance of hydrogen gas in reactions with metals?

Back

The production of hydrogen gas in reactions with metals indicates that a displacement reaction has occurred, often involving an acid.
