What is meant by the yield of a chemical reaction?
The yield of a chemical reaction describes how much product is made .
1 of 7
What factors can affect the yield of a chemical reaction?
Factors affecting the yield inculde product being left behind in apparatus. Reversible reactions not competing, some reactants may produce unexpected reactions, and losses in seperation of products from the reaction mixture.
2 of 7
Why is atom economy important in industrial processes?
It is important to maximise atom economy in industrial processes to conserve the Earth's resources and minimise pollution.
3 of 7
How is titration used ?
Titration is used to measure how accurately what volumes of acid and alkali react together completely.
4 of 7
State the meaning of the end point of a reaction?
This is the point at which a reaction between an acid and an alkali is complete which is called the end point of the reaction.
5 of 7
What apparatus is used to judge the end point of the reaction?
You use an acid/base indicator to show the end point of the reaction between an acid and an alkali.

What is the volume of any gas at room temperature and pressure?
The volume of 1 mole of any gas at room temperature and pressure is 24dm ( 24 000cm )
