Answer 5

-Both oxygen and water must be present
-Salt and acid causes iron to rust faster

Question 6

How to prevent rusting

Answer 6

Coating iron with paint/grease/plastic
Electroplating iron with layer of an another metal

Question 7

Reaction of metals with cold water (word eqn, & reactions)

Answer 7

Metal + cold water ~
mental hydroxide + hydrogen gas

Potassium
2K(s) + 2H2O (l) ~ 2KOH (aq) + H2 (g)
Sodium
2Na(s) + 2H2O (l) ~ 2NaOH (aq) + H2 (g)
Calcium
Ca(s) + 2H2O (l) ~ Ca(OH)2 (aq) + H2(g)
Magnesium
Mg(s) + 2H2O (l) ~ Mg(OH)2 (aq) + H2

Question 8

Reaction of metals with steam(word eqn, & reactions)

Answer 8

metal + steam ~ metal oxide + hydrogen gas

Potassium, Sodium, Calcium
Reacts too explosively (too dangerous)

Iron reacts slowly

Question 9

Reaction of metals with hydrochloric acid (word eqn, & reactions)

Answer 9

metal + hydrochloric acid ~ met chloride + hydrogen gas

Potassium and sodium reacts too explosively

Question 10

cold water
steam
hydrochloric acid

Answer 10

(s) + (l) ~ (aq) + (g)
(s) + (g) ~ (s) + (g)
(s) + (aq) ~ (aq) + (g)
