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.
"Spherical: Bacteria shaped like a ball are called cocci, and a single bacterium is a coccus. Examples include the streptococcus group, responsible for “strep throat.”
Rod-shaped: These are known as bacilli (singular bacillus). ...
Spiral: These are known as spirilla (singular spirillus).

The number of electrons in an atom is directly proportional to the number of protons, which is clearly represented by atomic number.
If you were to notate all of the electron configurations of the atoms in the 2nd row, you would clearly see an increase in the number of valence electrons from left to right.

i am doing this in science also i would like to know if u know
Explanation:
Answer:
Water molecules have strong cohesive forces thanks to their ability to form hydrogen bonds with each other.
Explanation:
Cohesion refers to the attraction of molecules by other molecules of the same type.
The structure of the water molecule is given by two hydrogen atoms and one oxygen atom that are held together by covalent bonds. It is a polar molecule and consequently forms bonds called hydrogen bonds with other molecules.
