hello, can someone help? i’ve been stuck on this for a few days... it will be greatly appreciated if u help T-T thanks in advance

A

B

C

Explanation:

Remark

Delta H is put on the reactant side of the equation. If delta H is plus the reaction goes to the right. If anything causes delta H to decrease, the reaction shifts left when delta H is originally negative.

One

Delta H is positive which means that heat has to be added before the reaction can take place. If the temperature decreases, then H2 will decrease because delta H is fighting off the temperature decrease The answer is A

Two

Pressure decreases. The side (left or right) with the most number of moles will be favored. The left side has 2 moles. The right side has 4 moles. The right side is favored. B

Three

The concentration of NH3 increases. That will increase the products. H2 increases. Answer C

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates
