Molar mass of sodium=23g
2 mole sodium gives 2 g H2
i.e 46g sodium gives 2g H2
so 65.4g will give=2.84g H2
now no. of molecules = 2.8/2*avogadros number

Water can be formed in the following reaction:
Komok [63]

The  moles  of  oxygen  gas (O2) that is needed is    4  moles


 Explanation

2H2 +O2 → 2H2O

The  moles of O2  is determined using the mole  ratio  of H2:O2

that is from equation  above H2:O2  is 2:1  

If the moles of H2  is 8  moles therefore  the moles  of O2

 = 8 moles x 1/2  = 4 moles

K3PO4+AgNO3--&gt; ???<br> Ba(HCO3)2+Ba(OH2)--&gt;
GuDViN [60]

<u>Explanation:</u>

A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.

  • <u>For 1:</u>

When potassium phosphate reacts with silver nitrate, it leads to the formation of silver phosphate and potassium nitrate.

The balanced chemical equation follows:

3AgNO_3+K_3PO_4\rightarrow Ag_3PO_4+3KNO_3

  • <u>For 2:</u>

When barium bicarbonate reacts with calcium hydroxide, it leads to the formation of barium carbonate, calcium carbonate and water

The balanced chemical equation follows:

Ba(HCO_3)_2+Ca(OH)_2\rightarrow BaCO_3+CaCO_3+2H_2O
