How many hydrogen atoms are in each of the formulas in Question 1?Question 1How many

Solution 36P

Here, we are going to calculate the number of Hydrogen atoms (H)  present in each  molecular compound.

Atom is the smallest tiny representation of an atom.

Chemical formula is the representation of the number of atoms present in the molecule or molecular compound .

(a) H3PO4

3 H + P + 4O -----> H3PO4

Here, molecular compound H3PO4 (phosphoric acid) is composed of  three hydrogen atoms (H) , one phosphorus atom (P) and four oxygen atoms (O).

Thus, the  molecular compound H3PO4 (phosphoric acid) has three(3) hydrogen atoms (H).

(b) Na2HPO4

2Na + H +P + 4O -----> Na2HPO4

Here,  molecular compound Na2HPO4 (sodium phosphate) is composed of  two sodium atoms (Na), one  hydrogen atoms (H) , one phosphorus atom (P) and four oxygen atoms (O).

Thus, the  molecular compound  Na2HPO4 (sodium phosphate) has one (1) hydrogen (H) atom.

(c) Ca(HCO3)2

Ca + 2H +2C + 6O -----> Ca(HCO3)2

Here,  molecular compound Ca(HCO3)2 (calcium bicarbonate) is composed of  one calcium atom (Ca), two hydrogen atoms (H) , two  carbon atoms (C) and six oxygen atoms (O).

Thus, the  molecular compound Ca(HCO3)2 (calcium bicarbonate)  has two (2) Hydrogen (H) atoms.

(d) Ba(C2H3O2)2

Ba + 6H +4C + 4O -----> Ba(C2H3O2)2

Here,  molecular compound Ba(C2H3O2)2(barium acetate) is composed of  one Barium  atom (Ba), six hydrogen atoms (H) , four  carbon atoms (C) and four oxygen atoms (O).

Thus, the  molecular compound Ba(C2H3O2)2(barium acetate)  has six(6) Hydrogen atoms (H).
