When $10 \, mL$ of $10 \, M \, H_2SO_4$ solution is mixed with $100 \, mL$ of $1 \, M \, NaOH$ solution,the resulting solution will be .......

$0.5 \ mol$ of $H_2SO_4$ is mixed with $0.2 \ mol$ of $Ca(OH)_2$. What is the maximum number of moles of $CaSO_4$ formed?

$CNG$ 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]
