One mole of calcium phosphide on reaction with excess water gives

What will be the volume of the mixture after the reaction? $litre$
$NH_3(4 \ litre) + HCl(1.5 \ litre) \to NH_4Cl(s)$

What are the combustion products of an aliphatic thiol $(RSH)$ at $298 \ K$?

Assertion : The amount of the products formed in a reaction depends upon the limiting reagent.
Reason : Limiting reactant reacts completely in the reaction therefore limits the amount of product.

Identify the values of $A$,$B$,$C$,$D$ and $E$ for the following unbalanced reaction: $aKNO_3 + 5C_{12}H_{22}O_{11} \rightarrow bN_2 + cCO_2 + dH_2O + eK_2CO_3$

$CNG$ is an important transportation fuel. When $100 \, g$ of $CNG$ is mixed with $208 \, g$ of oxygen in vehicles,it leads to the formation of $CO_2$ and $H_2O$ and produces a large quantity of heat during this combustion. The amount of carbon dioxide produced in grams is ...... [nearest integer] [Assume $CNG$ to be methane]
