Answer:
P(N₂) = 2.5 atm
Explanation:
Given data:
Total pressure of gasses = 6.7 atm
Partial pressure of O₂ = 3.0 atm
Partial pressure of CO₂ = 1.2 atm
Partial pressure of N₂ = ?
Solution;
According to Dalton law of partial pressure,
The total pressure inside container is equal to the sum of partial pressures of individual gases present in container.
Mathematical expression:
P(total) = P₁ + P₂ + P₃+ ............+Pₙ
Now we will solve this problem by using this law.
P(total) = P(O₂) + P(CO₂) + P(N₂)
6.7 atm = 3.0 atm + 1.2 atm + P(N₂)
6.7 atm = 4.2 atm + P(N₂)
P(N₂) = 6.7 atm - 4.2 atm
P(N₂) = 2.5 atm
Oxygen is used up and glucose is broken down.
Answer:
<u>Effect of adding heat to the reactions</u>
1. Shift the Reaction <em><u>backward</u></em> in First graph.
2.Shift the Reaction <em><u>forward</u></em> in second graph.
<u>Other ways to change the rate of a chemical reaction are :</u>
1. Addition of Catalyst
2.Increase in surface area
3. Increase in concentration of reactant.
Explanation:
Graph 1
It shows that the reaction is exothermic in which heat is released.
According to Le-Chatelier's rule : If temperature is increased
(heat is added) in an exothermic reaction , it will shift in backward direction.
Graph 2.
It shows that the reaction is endothermic in which heat is absorbed (taken)
According to Le-Chatelier's rule : If temperature is increased
(heat is added) in an endothermic reaction , it will shift in forward direction.
The correct answer to this item is letter
C. convection in earth's mantle
Convection currents move tectonic plates when the rising mantle creates heat inside. The radioactive decay of several substances is responsible for the creation of the convection currents.
