Calculate the mass of $AgCl$ precipitated when $25 \ mL$ of $35 \%$ solution of $AgNO_3$ and $25 \ mL$ of $11.6 \%$ solution of $NaCl$ are mixed. (in $g$)

An electric discharge is passed through a mixture containing $50 \, c.c.$ of $O_2$ and $50 \, c.c.$ of $H_2$. The volume of the gases formed $(i)$ at room temperature and $(ii)$ at $110 \, ^oC$ will be

In the given reaction,$X + Y + 3 Z \rightleftharpoons XYZ_3$. If one mole of each of $X$ and $Y$ with $0.05 \ mol$ of $Z$ reacts to form the compound $XYZ_3$,calculate the yield of $XYZ_3$ in grams. (Given: Atomic masses of $X, Y$ and $Z$ are $10, 20$ and $30 \ amu$,respectively). (Nearest integer)

Balance the following chemical equation by choosing the correct option for the coefficients $x, y, p, q, r,$ and $s$.
$x KNO_3 + y C_{12}H_{22}O_{11} \longrightarrow p N_2 + q CO_2 + r H_2O + s K_2CO_3$

$5 \, \text{moles}$ of $A$,$6 \, \text{moles}$ of $B$,and an excess amount of $C$ are mixed to produce a final product $D$,according to the reactions:
$A + 2B \to I$
$I + C \to B + D$
What is the maximum number of moles of $D$ that can be produced,assuming that the products formed can be reused in the reactions?

$20 \ mL$ of $0.1 \ M$ $HCl$ is added to $30 \ mL$ of $0.1 \ M$ $NaOH$. To this solution,an extra $50 \ mL$ of water was added. What is the molarity of the final solution formed (in $M$)?
