Which is a correctly balanced equation for a reaction between hydrogen gas and oxygen gas?
A) 2 H2(g) + 2 O2(g) → H2O(g) + heat
B) H2(g) + O2(g) + 2 H2O(g) + heat
C H2(g) + O2(g) → H2O(g) + heat
D) 2 H2(g) + O2(g) + 2 H2O(g) + heat

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.
