Name the metals that can be extracted by electrolysis.

Potassium, Sodium, Calcium, Magnesium, Aluminium

Reaction that absorbs heat energy from the surrounding.

Endothermic

What is the metal extracted from haematite?

Iron

Gas bubbles are produced when X is added to hydrochloric acid. Give an example of X?

Eggshell/Shell/Coral/Limestone

What can be observed if the mixture of aluminium oxide and carbon is heated?

No reaction

Marble and galena are minerals that exist in the form of _______ in the Earth's crust.

compounds

When endothermic reaction occurs, the surrounding temperature _____.

decreases

Calcium carbonate + hydrochoric acid ---> __________ + ___________ + ___________

Calcium chloride + Carbon dioxide + Water

Where is the position of carbon in the reactivity series of metals?

Between aluminium and zinc

State the relationship between the vigor of the reaction and the reactivity of metal to oxygen.

The more vigorous the metal reacts with oxygen, the more reactive the metal is to oxygen.

Give an example of exothermic reaction in daily life

Combustion/Respiration/Neutralisation/Freezing/Rusting of iron/etc

Why does the mixture of carbon and zinc oxide glow when heated?

Carbon is more reactive than zinc, so, it can remove oxygen from zinc oxide to zinc.

Arrange these metals in ascending order of reactivity (Aluminium, Calcium, Zinc, Lead, Copper, Tin)

Copper, Lead, Tin, Zinc, Aluminium, Calcium

Why is the glass wool used in this experiment?

To prevent potassium manganate (VII) crystals from mixing with the metal powder.

From which part of the blast furnace is the slag removed?

B

What gas is released when calcium carbonate is heated?

Carbon dioxide

What is the substance produced in this activity?

Metal oxide

What is the function of potassium manganate (VII) crystal?

To provide oxygen

If a blast furnace is used in the extraction of tin ore, name all the reactants added into the blast furnace.

Tin (IV) oxide/Cassiterite , Coke/Carbon, Limestone/Calcium carbonate

Branch of science that studies the changes in heat energy in chemical reactions.

Thermochemistry
