Question 7

Examples of acid + metal

Answer 7

2HCI + Mg –MgCl2 + H2 (Magnesium Chloride)

H2S04+ Mg –MgS04 + H2

Question 8

How can you test for hydrogen?

Answer 8

Use a lighted splint and hydrogen will make a ‘squeaky pop’ with a lighted splint
The noise comes from the hydrogen burning with the oxygen in the air to form water

Question 9

Acid + Metal Carbonate —

Answer 9

Salt + Water + Carbon Dioxide

Question 10

Examples of Acid + Metal Carbonate—-

Answer 10

2HCI + Na2CO3 - 2NaCI + H20 + CO2 (Sodium Chloride)
H2S04 + K2CO3 -K2SO4 + H20 + CO2 (Potassium Sulfate)
2HNO3 + ZnCO3 - Zn(NO3)2 + H20 + CO2 (Zinc Nitrate)

Question 11

How can you test for carbon dioxide?

Answer 11

Bubbling it through limewater

If the gas is carbon dioxide, the limewater will turn cloudy
