First of all for comparing any two quantities , they must be in same units .
Here one unit is in grams and other in milligrams .
So let's convert gram to miligram .
We know that 1 gram = 1000 mg.
So , 0.7g = 0.7 × 1000 mg = 700mg .
Clearly 711mg > 700mg .
Hence 711mg is Greater than 0.7 g .
CO because it is the chemical symbol for the element cobalt whereas the rest are compound. H20 is water, CO2 is carbon dioxide and N2 is dinitrogen.
"A" is the answer. The chemical reaction is when the batter becomes brown.
B is mixing C is mass becoming a liquid and D. is dissolving no chemical reaction happened there.
Hope that helps!
