Reactions Remediation

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 Br₂ (l) + KI (aq) react based on the activity series?

Back

Yes, the reaction will occur because bromine is more reactive than iodine.

Front

What is the balanced equation for the reaction of hydrogen and chlorine?

Back

H₂ + Cl₂ → 2HCl.

Front

How many moles of HCl are produced from 3 moles of H₂?

Back

6 moles of HCl are produced.

Front

What type of reaction is Al(OH)₃ → Al₂O₃ + H₂O?

Back

This is a decomposition reaction.

Front

What is the solubility of lead (II) phosphate?

Back

Lead (II) phosphate is insoluble in water.

Front

Which compounds are always soluble in water?

Back

Nitrates are always soluble in water.

Front

Define a decomposition reaction.

Back

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

Front

What is the general form of a single replacement reaction?

Back

A + BC → AC + B, where A replaces B in the compound.

Front

What is the difference between soluble and insoluble compounds?

Back

Soluble compounds dissolve in water, while insoluble compounds do not dissolve significantly.
