What should be the weight and moles of $AgCl$ precipitate obtained on adding $500 \ mL$ of $0.20 \ M$ $HCl$ to $30 \ g$ of $AgNO_3$ solution (in $g$)? (Molar mass of $AgNO_3 = 170 \ g/mol$)

In a $1 \ L$ vessel,$10 \ \text{moles}$ of methane and $50 \ \text{moles}$ of $O_2$ are present. The number of moles of $O_2$,water,and $CO_2$ present in the vessel after the vessel is heated to burn methane completely are respectively:

The reaction of $1 \ mol$ of calcium phosphide with excess water gives .......

$50.0 \ kg$ of $N_{2(g)}$ and $10.0 \ kg$ of $H_{2(g)}$ are mixed to produce $NH_{3(g)}$. Calculate the amount of $NH_{3(g)}$ formed. Identify the limiting reagent in the production of $NH_{3(g)}$ in this situation.

Calculate the weight of $FeO$ produced from $6.7 \ g$ of $VO$ and $4.8 \ g$ of $Fe_2O_3$ using the reaction: $2VO + 3Fe_2O_3 \rightarrow 6FeO + V_2O_5$ $(V = 51, Fe = 56)$ (in $g$)

The set of numerical coefficients that balances the equation $K_2CrO_4 + HCl \to K_2Cr_2O_7 + KCl + H_2O$ is
