Answer:

0.17094 liters

Explanation:

-For STP, Pressure=1 atm and Temperature=273K

-We apply the combined gas law which relates temperature, pressure and Volume:

\frac{PV}{T}=k

-We therefore equate the relationship at different temperatures as follows:

\frac{P_1V_1}{T_1}=\frac{P_2V_2}{T_2}\\\\\frac{1\times 1.4\ }{273}=\frac{1.2\times V_2}{40}\\\\V_2=\frac{1\times 1.4\ }{273}\times \frac{40}{1.2}\\\\=0.17094\ L

Hence, the new volume is 0.17094 liters

Consider an endothermic reaction C(s) CO2(g)2CO(g) If such a system at equilibrium is heated and compressed at the same time, wh
RSB [31]

Answer:

A. It will shift to the left

Explanation:

In the equilibrium:

C(s) ⇄ CO2(g)2CO(g)

The system will shift to the right if any change stimulate the production of gas -LeChatelier's principle-; in the same way, if a change doesn't favors the production of gas the system will shift to the left producing less gas.

The changes that increasing the pressure of the system, doesn't favors the gas production doing the system shift to the left.

A gas that is heated expands itsellf doing the pressure increases.

In the same way, if you compress the gas, the gas increases its pressure.

Thus, both changes increase pressure of the gas doing the system shift to the left.

<h3>A. It will shift to the left </h3>

Vikki [24]
<h2>Answer:</h2>

It means the waves collides and constructive interference occurred.

<h3>Explanation:</h3>

If the two waves coming from the opposite direction collide with each other, there are two way of their interference.

  • Constructive interference: An interference which results in the increase in energy. And it is when crust of a wave comes on the crust of second wave.
  • Destructive interference: An interference which results in decrease in energy of the resulting wave and colliding waves cancel the result of each other.

Hence in experiment there will be constructive interference.
