D is the answer I believe.
The correct answer should be D :)
Answer:
Us we know mass is constant any where .
Given :-
W=100N gravity=G=10 meter per second square
H=300M
W=M*G
w=m*10m/second square
100=M*10
M=10kg
P.E=M*G*H
P.E=10*10*300
P.E=30,000J
Answer:
C) at equilibrium, the concentration of C will be much greater than the concentration of A or B.
Explanation:
A + B ⇌ C; ΔG° = -20 kJ·mol⁻¹
If ΔG is negative, the reaction is spontaneous and position of equilibrium lies to the right, so the equilibrium concentration of C is much greater than that of A or B.
A) is wrong. The molar ratio of A:B is 1:1. If their initial concentrations are 1 mol·L⁻¹, their final concentrations will be equal.
B) is wrong. The position of equilibrium lies to the right, so the concentration of C will be much greater than that of A.
D) and E) are wrong. ΔG says nothing about the rate of a reaction. It deals with the spontaneity and position of equilibrium not the speed at which equilibrium is achieved.
C. Mitosis
Mitosis is a process where a single cell divides into two identical daughter cells.
The purpose of which is for growth and to replace worn out cells.
