Answer:
Ca(OH)2______CaO + H2O
Step-by-step explanation:
looking at the equation it is balanced so this is the right equation for the reaction
you probably might be wondering how I got their compound formula right?
well its simple
for calcium hydroxide you have
calcium ____Ca^2+
hydroxide ____OH^- note those charges are their valency
so the valencies cross to be a sub scripts
so we have
Ca(OH)2
same is applicable to others
that's all
