Answer : The volume of NH_3 produced will be, 0.8 liters.

Explanation : Given,

Volume of H_2 = 1.2 L

At STP, 1 mole of substance contains 22.4 L volume of substance.

The given balanced chemical reaction is:

N_2+3H_2\rightarrow 2NH_3

From the balanced chemical reaction we conclude that,

As, 3\times 22.4L volume of H_2 produced 2\times 22.4L volume of NH_3

So, 1.2L volume of H_2 produced \frac{2\times 22.4L}{3\times 22.4L}\times 1.2L=0.8L volume of NH_3

Therefore, the volume of NH_3 produced will be, 0.8 liters.

The volume of a sample gas, initially at 25 C and 158 mL, increased to 450 mL. What is the final temperature of the sample of ga
Rashid [163]

Answer:

Final temperature of the gas is  576 ^{0}\textrm{C}.

Explanation:

As the amount of gas and pressure of the gas remains constant therefore in accordance with Charles's law:

                                       \frac{V_{1}}{T_{1}}=\frac{V_{2}}{T_{2}}

where V_{1} and V_{2} are volume of gas at T_{1} and T_{2} temperature (in kelvin scale) respectively.

Here V_{1}=158mL , T_{1}=(273+25)K=298K and V_{2}=450mL

So  T_{2}=\frac{V_{2}T_{1}}{V_{1}}=\frac{(450mL)\times (298K)}{(158mL)}=849K 

849 K = (849-273) ^{0}\textrm{C} = 576 ^{0}\textrm{C}

So final temperature of the gas is  576 ^{0}\textrm{C}.
