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.
Answer: all mass takes up space. everything has mass. Theres a unit of mass called a slug thats not the bug!
Explanation:
Answer : The number of grams of calcium perchlorate is, 0.00253 grams.
Explanation :
Molar mass of calcium perchlorate = 238.9 g/mol
As, 
formula units present in 238.9 g of calcium perchlorate
So, 
formula units present in 
of calcium perchlorate
Therefore, the number of grams of calcium perchlorate is, 0.00253 grams.
