What is the Lewis dot structure for calcium hydroxide

Calcium hydroxide is formed by one Ca2+ cation and two OH− anions, which implies that its chemical formula will be Ca(OH)2.

Here's how you'd figure this out. If you look at the periodic table, you'll see that calcium is in group 2. That means that it has two valence electrons that it must give up in order to be stable.

On the other hand, oxygen is in group 6, which means it needs 2 electrons in order to be stable. It gets one electron from a hydrogen atom to form an OH− anion. Now it only needs one more electron, which it gets from the two calcium has to offer.

This means that you'd need two OH− groups to form calcium hydroxide, since each OH− group would get one electron from calcium → Ca(OH)2.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products

answer: they produce more slow than unicellular organisms.
