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.
In a nucleotide, we find CARBOHYDRATE making up a piece of the nucleotide itself. An example of the type of carbohydrate found in nucloetides is de-oxy ribose. Deoxyribose is a five carbon sugar {pentose} which is part of the building blocks of nucleotide.<span />
Answer:
22.0 g
Explanation:
To find the mass, multiply the volume by the density.
8 cm³ × 2.75 g/cm³ = 22.0 g
The marble is 22.0 g.
Answer: 86.7 %
Explanation:
To calculate the moles, we use the equation:
a) moles of 
According to stoichiometry :
1 moles of give = 1 mole of 
Thus 0.307 moles give =
of
Mass of 
Therefore, the percent yield for the reaction is, 86.7%
