How many moles of oxygen are in 1.6 mol of ca(no3)2?

Answer : The moles of oxygen are, 9.6 moles.

Explanation : Given,

Moles of = 1.6 mole

As we know that,

In , there are 2 atoms of nitrogen, 1 atom of calcium and 6 atom of oxygen.

Now we have to calculate the moles of oxygen.

As, 1 mole of contains 6 moles of oxygen.

So, 1.6 moles of contains moles of oxygen.

Therefore, the moles of oxygen are, 9.6 moles.

the number of valence electrons for each molecule or ion is shown beneath the structure. remember hydrogen will not have more than two electrons. this hydrogen is part of a covalent bond (sharing two electrons). a double bond here would cause hydrogen to share four electrons with phosphorus.

a. energy is absorbed in the reaction.

if in a given reaction the energy of products is greater than the energy of reactants it means that reaction is endothermic and during the reaction, the energy is absorbed by reactants. in an endothermic reaction, the products have more stored chemical energy than the reactants. and in this reaction the reactants are more stable than products before the compounds with less energy are always more stable.
