increases down the group

Front (Question)

Reaction of Mg with water

Back (Answer)

Mg (s) + 2H2O (l) → Mg(OH)2 (aq) + H2 (g)

Front (Question)

Reaction of Mg with steam

Back (Answer)

Mg (s) + H2O (g) → MgO (s) + H2 (g)

Front (Question)

What is observed during the reaction of Mg with steam?

Back (Answer)

• white solid, MgO, produced • Bright light

Front (Question)

Equation for use of Mg in the extraction of ti from TiCl4

Back (Answer)

TiCl4 + 2Mg → 2MgCl2 + Ti

Front (Question)

Role of Mg in the extraction of Ti from TiCl4

Back (Answer)

Mg 2+ (aq) + 2OH - (aq) → Mg(OH)2 (s)

#10

Front (Question)

Observation for production of Mg(OH)2 in it’s simplest ionic equation

Back (Answer)

white precipitate, Mg(OH)2, produces

#11

Front (Question)

Use of Mg(OH)2

Back (Answer)

indigestion relief = neutralises stomach acid

#12

Front (Question)

Solubility of group 2 sulphates (increases/ decreases) down the group

Back (Answer)

decreases

#13

Front (Question)

How soluble is BaSO4?

Back (Answer)

insoluble

#14

Front (Question)

Simplest ionic equation for the production of BaSO4

Back (Answer)

Ba 2+ (aq) + SO4 2- (aq) → BaSO4 (s)

#15

Front (Question)

Observation for the production of BaSO4

Back (Answer)

white precipitate forms

#16

Front (Question)

Use of BaSO4

Back (Answer)

taking X-rays of the stomach (Barium meal) Ba = toxic → can be given as BaSO4 is insoluble
