Nitroglycerine decomposes violently according to the chemical equation below. What mass of carbon dioxide gas is produced from t

AveGali [126]

Answer : The mass of $CO_2$ produced is, 7.74 grams

Solution : Given,

Mass of $C_3H_5(NO_3)_3$ = 13.3 g

Molar mass of $C_3H_5(NO_3)_3$ = 227 g/mole

Molar mass of $CO_2$ = 44 g/mole

First we have to calculate the moles of $C_3H_5(NO_3)_3$ .

$\text{ Moles of }C_3H_5(NO_3)_3=\frac{\text{ Mass of }C_3H_5(NO_3)_3}{\text{ Molar mass of }C_3H_5(NO_3)_3}=\frac{13.3g}{227g/mole}=0.0586moles$

Now we have to calculate the moles of $CO_2$

The balanced chemical reaction is,

$4C_3H_5(NO_3)_3\rightarrow 12CO_2(g)+6N_2(g)+10H_2O(g)+O_2(g)$

From the reaction, we conclude that

As, 4 mole of $C_3H_5(NO_3)_3$ react to give 12 mole of $CO_2$

So, 0.0586 moles of $C_3H_5(NO_3)_3$ react to give $0.0586\times \frac{12}{4}=0.176$ moles of $CO_2$

Now we have to calculate the mass of $CO_2$

$\text{ Mass of }CO_2=\text{ Moles of }CO_2\times \text{ Molar mass of }CO_2$

$\text{ Mass of }CO_2=(0.176moles)\times (44g/mole)=7.74g$

Thus, the mass of $CO_2$ produced is, 7.74 grams

Water take a (long/short) time to heat up due to it's High Specific Heat.

7nadin3 [17]

Because of water's specific heat capacity, it takes longer for the water to heat up. This is useful because if water heated up quickly, then the ocean would be literally boiling, and it would evaporate into the atmosphere.
