Answer:
because in winter root will freeze and when root freeze the tree will die.
Answer:
Explanation:
CH₄ + 2O₂ = CO₂ + 2H₂O
C₂H₄ + 3O₂ = 2CO₂ + 2H₂O
Let volume of CH₄ be V , so volume of C₂H₄ will be 5 - V
CH₄ + 2O₂ = CO₂ + 2H₂O
1 vol 2 vol
V 2 V
V vol of CH₄ will require 2 V of O₂
C₂H₄ + 3O₂ = 2CO₂ + 2H₂O
5 - V 3( 5 - V )
5 - V vol of C₂H₄ will require 3 ( 5 - V ) vol of oxygen .
Total oxygen required = 2 V + 3 ( 5 - V )
2 V + 3 ( 5 - V ) = 13.2
2 V + 15 - 3V = 13.2
V = 1.8 ml
vol of CH₄ = 1.8
vol of C₂H₄ = 5 - 1.8 = 3.2 ml.
Answer: 303 ml
Explanation:
To calculate the final volume of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
Thus volume of the gas at 20.0°C if there is no change in pressure is 303 ml
