If x g of sodium chloride is decomposed by 4.9 g of sulphuric acid, 6 g of sodium bisulphate (NaHSO4) and 1.825 g of hydrogen chloride are produced in the reaction. If the law of conservation of mass holds true, then find the value of 10x :

The correct option is A 29We have :NaCl+H2SO4→NaHSO4+HClso, mass of reactant = x+4.9gmass of product = 6+1.825=7.825gtherefore, we have x+4.9=7.825x=2.925ghence, 10x=29gHence, the correct option is A.

If $x$ g of sodium chloride is decomposed by $4.9$ g of sulphuric acid, $6$ g of sodium bisulphate $(N a H S O_{4})$ and $1.825$ g of hydrogen chloride are produced in the reaction. If the law of conservation of mass holds true, then find the value of $10 x$ :

The correct option is A $29$
We have :

$N a C l + H_{2} S O_{4} \to N a H S O_{4} + H C l$

so, mass of reactant = $x + 4.9 g$

mass of product = $6 + 1.825 = 7.825 g$

therefore, we have $x + 4.9 = 7.825$

$x = 2.925 g$

hence, $10 x = 29 g$

Hence, the correct option is A.
