Group 2 reactions + Observations

Question 1

When group 2 metals react with cold water what is produced + Observation?

Answer 1

= metal hydroxide + hydrogen
= efferverescene

Question 2

When group 2 metals react with steam what is produced + observation?

Answer 2

= metal oxide + hydrogen
= observation: white precipitate is formed

Question 3

Does berrrilyum undergo these reactions?

Answer 3

no

Question 4

What happens when group 2 metal oxides reacts with water?

Answer 4

= metal hydroxide
= (MgO) is slow

Question 5

WHat happens when group 2 metals react with acid?

Answer 5

= salt
= hydrogen

Question 6

What happens when group 2 metal oxides react wuth acid?

Answer 6

= salt + water

Question 7

What happens to the reactivity of group 2 metals?

Answer 7

= reacts more vigorously going down the group

Question 8

What different reaction happens when magniesium reacts with warm water?

Answer 8

= magnesium hydroxie
= slower reaction then steam

Question 9

What observations might be seen?

Answer 9

= fizzing- more vigorous down the group
= metal dissolving- more faster down the group
= solution heating up- more down the group
=
