Running cars on electricity would conserve gasoline because electric cars do not use the same resources.

Hope this helps!

Answer: A) conserve gasoline.

Fueling the cars with electricity offers some benefits over conventional fueling cars, these vehicles react quickly, these can be charged easily and efficiency of the vehicle increases. Most importantly this initiative can help in the conservation of the fuels like coal, natural gas and gasoline which are non-renewable sources of energy. All these energy resources utilized by the cars or any other transportation vehicle releases toxic chemical gases which are responsible for pollution. The running cars on electricity is likely to produce less pollution than conventionally fueled cars.

How much heat is absorbed/released when 20.00 g of NH3(g) reacts in the presence of excess O2 (g) to produce NO (g) and H2O (l)

FrozenT [24]

Answer:

a. 342.9 kJ of heat are absorbed.

Explanation:

Calculation of the moles of $NH_3$ as:-

Mass = 20.00 g

Molar mass of $NH_3$ = 17.031 g/mol

The formula for the calculation of moles is shown below:

$moles = \frac{Mass\ taken}{Molar\ mass}$

Thus,

$Moles= \frac{20.00\ g}{17.031\ g/mol}$

$Moles= 1.1743\ mol$

Given that:- $\Delta H=+1168\ kJ$

It means that 1 mole of $NH_3$ undergoes reaction and absorbs 1168\ kJ of heat

So,

1168 mole of $NH_3$ undergoes reaction and absorbs $1168\times 1168\ kJ$ of heat

<u>Amount of heat absorbed = + 342.9 KJ</u>

1. A given mass of air has a volume of 6.00 L at 80.0°C. At constant pressure, the temperature is

earnstyle [38]

3 L will be the final volume for the gas as per Charle's law.

Answer:

Explanation:

The kinetic theory of gases has two significant law which forms the backdrop of motion of gases. They are Charle's law and Boyle's law. As per Charle's law, the volume of any gas molecule at constant pressure is directly proportional to the temperature of the molecule.

V∝ T

Since, here two volumes are given and at two different temperatures with constant pressure. Then as per Charle's law, the relation between the volumes of air at different temperature will be

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

So in this case, V1 = 6 L and T1 = 80° C. Similarly, T2 = 40° C. So we have to determine the V2.

$\frac{6}{80}=\frac{V_{2} }{40}$

$V_{2}=\frac{6*40}{80}=3 L$

So, 3 L will be the final volume for the gas as per Charle's law.
