3 Cu + 8HNO3 → 3 Cu(NO3)2 + 2 NO + 4 H2O
In the above equation, how many grams of water can be made when 10.3 moles of HNO3 are consumed?

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.

Replicate prove reliability and validity

I'm guessing its b crude oil

Copper does not react with dilute sulphuric acid as its reduction potential is higher than that of hydrogen
