Explanation / Answer

NH4NO2 -------> N2 + 2H2O

2Al + Fe2O3 -----> Al2O3 + 2Fe

CaCN2 + 3H2O ----->CaCO3 + 2NH3

3NO2 + H2O ----> 2HNO3 + NO

Moles of H = 21.86 x 27.7 / 1 x 100 = 6.05522

Moles of B = 78.14 x 27.7 / 10.8 x 100 = 2.004

B2H6

Moles of C = 42.1 x 342.3 / 12 x 100 = 12

Moles of H = 6.49 x 342.3 / 1 x 100 = 22.2

Moles of O = 51.41 x 342.3 / 16 x 100 = 11

=> C12H22O11

BeCl2 --> Beryllium chloride (Trigonal planar)

TiCl4 ---> Titanium Chloride (Tetrahedral)

O3----> Ozone (bent shaped)

SF6---->Sulfur Hexafluoride (Octahedral)

PCl3 ---> phosphorus tricholride

PCl5 ---> phosphorus pentachloride

P4O7 ---> Tetraphosphorus Heptoxide

SeO3 --> Selenium trioxide

N2O5 ---> dinitrogen pentoxide

P4O6 ---->Tetraphosphorus hexoxide

SiO2 --> Silicon dioxide

SeO2 -----> Selenium dioxide
