Answer:What are the two half reactions that show how many electrons are gained or lost by each species in the reaction:
Ni2+(aq) + Mg(s) → Ni(s) + Mg2+(aq)?
atoms cannot be created or destroyed in a chemical reaction
Answer:
Lactate dehydrogenase (LDH)
Explanation:
LDH is tetrameric enzyme found in the muscles (M-type) and the heart (H-type) of living cells, responsible for the conversion of pyruvate to lactate and back, to promote generation of nicotinamide adenine dinucleotide (NAD).
There is no picture or any thing that could help me help you
CO2 is not polar as in this case the same types of molecules
are pulling in the same as well as opposite direction. CH4 is also not polar as
there is no imbalance in the charge of the molecules. CBr4 is also not polar
because in this case also no imbalance in the molecular charges can be seen.
CHBr3 is a bit polar in nature because it has different kind of charges at its
opposite ends. S among the all 4 options CHBr3 is polar.
I believe its the first one because manganese is mn and IV is 4 but the cross thing thing will making it the second one but then you have to simplify making it the first one i hope that helps:)
