an alkali earth metal. When Calcium
bumps into water, it
Will cause
water to fall apart. Calcium will then
join with one of the atoms of water.
Question:

compounds get formed?
Possibilities: These are the combinations that we can get
1. Calcium oxide CaO white
2. Calcium hydroxide CaOH white.
3. H2 Explosive gas
4. O2 flammable gas
Summarize
the demo
Put Calcium
metal into a beaker of coldish water.
Colour
change – milky white colour
Temperature
change – cold to hot. WE CALL THIS AN
EXOTHERMIC
REACTION.
Bubbles came
