Neutralization reactions:
\( \mathrm{H^+ + OH^- \rightarrow H_2O} \quad (\text{from HCl: } X), \)
\( \mathrm{2H^+ + 2OH^- \rightarrow 2H_2O} \quad (\text{from } H_2SO_4: Y). \)
From the reactions:
\( Y = 2X \implies \frac{Y}{X} = 2. \)
Final Answer: 2.
The enthalpy of combustion of methane is 890 kJ/mol. How much heat is released when 8 g of methane is burned completely? (Molar mass of CH\(_4\) = 16 g/mol)
Let $ f(x) = \begin{cases} (1+ax)^{1/x} & , x<0 \\1+b & , x = 0 \\\frac{(x+4)^{1/2} - 2}{(x+c)^{1/3} - 2} & , x>0 \end{cases} $ be continuous at x = 0. Then $ e^a bc $ is equal to
Total number of nucleophiles from the following is: \(\text{NH}_3, PhSH, (H_3C_2S)_2, H_2C = CH_2, OH−, H_3O+, (CH_3)_2CO, NCH_3\)
