Consider four sealed, rigid containers with the following volumes: 50 mL, 100 mL, 250 mL, and 500 mL. If each of these contains
dsp73
First, we assume that helium behaves as an ideal gas such that the ideal gas law is applicable.
                                     PV = nRT
where P is pressure, V is volume, n is number of moles, R is universal gas constant, and T is temperature. From the equation, if n, R, and T are constant, there is an inverse relationship between P and V. From the given choices, the container with the greatest pressure would be the 50 mL.

Hexane is a common laboratory solvent and a component of petrol. Its combustion reaction is as follows: 2 C6H14 (9) + 19 02(9) +
Flauer [41]

Answer : The heat released by the combustion of 1.121 mol of hexane (kJ) is, 1.01\times 10^3

Explanation :

The given balanced reaction is,

2C_6H_{14}(g)+19O_2(g)\rightarrow 12CO_2(g)+14H_2O(l)

Given:

Moles of hexane = 0.121 mol

\Delta H = -8326 kJ/mol

The negative sign indicate that the reaction exothermic or amount of heat released.

As, 1 mole of hexane released heat = 8326 kJ

So, 0.121 mole of hexane released heat = 8326 × 0.121 = 1007.446 ≈ 1.01\times 10^3kJ

Therefore, the heat released by the combustion of 1.121 mol of hexane is 1.01\times 10^3kJ.
