A sample of hydrogen gas at a pressure of 977 mm Hg and a temperature of 32 °C, occupies a volume of 11.3 liters. If the gas is
IrinaK [193]

Answer : The volume of gas sample will be, 9.93 L

Explanation :

Charles' Law : It states that volume of the gas is directly proportional to the temperature of the gas at constant pressure and number of moles of gas.

Mathematically,

\frac{V_1}{T_1}=\frac{V_2}{T_2}

where,

V_1\text{ and }T_1 are the initial volume and temperature of the gas.

V_2\text{ and }T_2 are the final volume and temperature of the gas.

We are given:

V_1=11.3L\\T_1=32^oC=(32+273)K=305K\\V_2=?\\T_2=-5^oC=(-5+273)K=268K

Now put all the given values in above equation, we get:

\frac{11.3L}{305K}=\frac{V_2}{268K}\\\\V_2=9.93L

Therefore, the volume of gas sample will be, 9.93 L

What is state symbols
Ganezh [65]

Answer:

Explanation:

State symbols are used in chemical equations to delineate the state of matter in which the reaction is taking place.

They give a good perspective of the state of the reactants and products obtainable.

There are basically four states of matter in every chemical reaction:

  • Solids are symbolized by small letter (s)
  • Liquids are represented by (l)
  • Gases are shown by (g)
  • Aqueous solutions having water as the medium by (aq)

These symbols appear as subscript in front of the chemical species.
