8B Reactions of group 1 elements

Question 1

what happens when you group 1 metal oxides

Answer 1

it because very dull and tarnished as since group 1 metal are very flammable they would catch on fire

Question 2

what is the general equation of metals with oxygen

Answer 2

4M9(s) + O2(g) —–> 2M2O(s)

Question 3

what is the general equation of metals with cl

Answer 3

2M(s) + Cl2(g) ——-> 2MCl(s)

Question 4

what are the observations made with group 1 metal reacting with H2O

Answer 4

1. the metal would float on water
2. fizzing would occur because of hydrogen forming
3. the metal would dissolve to form the colourless solution of metal hydroxide
4. if the metal is reactive enough it will catch on fire

Question 5

what is the equation of metals reacting with H2O

Answer 5

2M(s) + 2H2O(l) ——-> 2MOH(aq) + H2(g)

Question 6

what is the trend of reactivity in group 1 metal

Answer 6

increase down the group, because of shielding and increase distance between the outer most electrons
