The Correct answer is Carbon dioxide CO2.
The Explanation:
according to the diagram:
we can see that the arrows which going to A are from:
1- respirition of the tree . and the CO2 gas is the result and produced gas from respiration.
2- The Combustion went from Home : and the CO2 gas is also the produced gas from the combustion process.
∴ (A) refers to CO2 (carbon dioxide) gas.
Answer:
Explanation:
In the solution of AB , they are split to give ions as follows
AB ⇄ A⁺ + B⁻
Product of concentration of A⁺ and B⁻ in saturated solution of AB is constant .
This is called Ksp
Ksp = [A⁺] [ B⁻]
If product of concentration of A⁺ and B⁻ exceeds Ksp , the equilibrium shifts to the left side and excess ions come out of solution in the form of precipitate. So second option is the answer.
Answer:
c) (12×0.9889) + (13×0.01108)
Explanation:
Given data:
Percentage of C-12 = 98.89%
Percentage of C-13 = 1.108%
Atomic mass = ?
Solution:
98.89/100 = 0.9889
1.108/ 100 = 0.01108
Atomic mass = (12×0.9889) + (13×0.01108)
Atomic mass = (11.8668 + 0.144034)
Atomic mass = 12.01084
They are two representatives of the sublevels/energy levels.
