Sodium bicarbonate (NaHCO3) is commercially known as baking soda. How many grams and atoms of oxygen are there in 15 grams of so
ella [17]

Answer:

3 atoms of O

8.57g

Explanation:

The problem here is to find the mass of oxygen in the compound and the number of atoms of oxygen.

 The formula of the compound is:

 NaHCO₃;

   Here we have:

      1 atom of Na

     1 atom of H

     1 atom of C

     3 atoms of O

So there are 3 atoms of O

To find the mass of oxygen , we use the molar mass of oxygen;

     Molar mass of oxygen  = 16g/mol

 Mass of oxygen  = \frac{3(16)}{84.01}  x 15  = 8.57g

describe how carbon skeletons may vary and explain how this variation contibutes to the diveristy and complecity of organic mole
elena55 [62]

Answer:

Carbon is a highly covalent element due to the presence of four valence electrons in its outermost shell. This helps it bond covalently with other elements in various ways.

Carbon is known to be the backbone for most compounds. The carbon backbone vary in length and in the mode of bonding such as having the ability to from straight, branched, rings, double or triple bond which contibutes to the diversity and complexity of organic molecules.
