Calcium Hydroxide (Ca(OH)2) can actually be formed by the
reaction of Calcium Oxide (CaO) with water (H2O). The complete balanced
chemical reaction is:
<span>CaO + H2O
--> Ca(OH)2</span>
<span>The subscript 2 in (OH) means that there are 2 O and 2 H
on the product side. Hence, the equation is balanced already.</span>
The answer is : oxygen gas
In primitive earth's era, (possibly billions years ago), the earth still has't filled with living organism as it is today. Many scientist predicted that it was filled with singular-cells anaerobic organisms , which do not need oxygen to live
