The instructions below to make the salt copper sulphate from copper carbonate and sulphuric acid but the order of the steps has been jumbled up. Put the sentences in the correct order.
Match the key word to the description of the type of substance.
Metal carbonate + acid will produce metal salt + water + hydrogen
Sodium hydroxide reacting with sulphuric acid will produce sodium suphate and water.
To make sodium nitrate we need to use sulphuric acid.
Sunil wanted to investigate the reaction between marble chips and hydrochloric acid. He measured out 0.01 kg of marble chips and put it into 50 cm3 of dilute hydrochloric acid in a concal flask. He then monitored the mass of the reaction on a top-pan balance.
The graph of Sunil's results is shown below.
a) What was the starting mass in grams of the whole experiment?
