Can u balance Ca+H2O=H +Ca(OH)2?
Answers:
Ca +2 H2O --> 2 H + Ca(OH)2
Edit - as other users point out, the 2 H should be a single H2 (hydrogen gas), but I was just balancing the equation in its requested form.
no can you?
2Ca + 3H2O = 2HCaO3 + 2H2 ?
Agree with Jobbo
The important thing is to have the same number of each type of atom on both sides, so in this case we have two oxygens on one side and one on the other so we make it 2H2O:
Ca + 2H2O H2 + Ca(OH)2.
It's H2 rather than 2H because hydrogen gas exists as a molecule with 2 hydrogen atoms.
No i can't but u could research for a science sites. or u could ask ur teacher or ur friends or pearents.
Ca + H2O = H + Ca(OH)2
Ca + (2)H2O = (2)H + Ca(OH)2
Ca= 1 : Ca= 1
H= 4 : H= 4
O= 2 : O= 2
The H has to be H2 as hydrogen cannot exist as an atom in normal conditions.
Ca + 2H2O = H2 + Ca(OH)2
The calcium hydroxide [Ca(OH)2] formed is also known as limewater.
Not on it's own - you can if you also add oxygen:
2Ca + 2H2O + O2 =2Ca(OH)2
Ca + 2H2O ---> H2 +Ca(OH)2
don't forget hyrdrogen is a diatomic molecule ;-)
Ca + 2H20 = Ca(OH)2 + H2
Hydrogen gas evoled will be in the molecular form of H2.
