A gas has a volume of 6.6 L at a temperature of 40 C. What is the volume of
zaharov [31]

Answer:

6.07 L

Explanation:

It appears that the reading has been made at constant pressure .

At constant pressure , the gas law formula is

V/T = constant  V is volume and T is temperature of the gas.

V₁ / T₁ = V₂ / T₂

V₁ = 6.6 L ,

T₁ = 40°C

= 273 + 40

= 313 K

T₂ = 15+ 273

= 288K

V₂ = ?

Putting the values in the formula above

6.6 / 313  = V₂ / 288

V₂ = 6.07 L.

Hotosynthesis can be represented by 6CO2(g)+6H2O(l)⇌C6H12O6(s)+6O2(g) Which of the following will be false when the photosynthes
antoniya [11.8K]

Answer: Option (b) and (d) are correct.

Explanation:

An equilibrium reaction is defined as the reaction in which rate of forward reaction equals rate of backward reaction.

A photosynthesis reaction is the reaction in which plants in the presence of sunlight, water, and carbon dioxide make their own food.  

  • The amount of carbon dioxide consumed will be equal to the rate of formation of oxygen into the atmosphere.

Hence, the statement rate of formation of O_{2} is equal to the rate of formation of CO_{2} is true.

  • Concentration of oxygen may remain constant but it will not decrease. Hence, the statement concentration of O_{2} will begin decreasing, is false.
  • As both oxygen and carbon dioxide are present in an equilibrium reaction, So, their concentration will not change.

        Hence, the statement concentrations of CO_{2} and O_{2} will not change, is true.

  • Concentration of carbon dioxide and oxygen will also depend on the limiting reagent. So, it is not necessary that the concentrations of CO_{2} and O_{2} will be equal.

Some amount of carbon dioxide might escape out into the air.

Hence, the statement concentrations of CO_{2} and O_{2} will be equal, is false.
