Suppose that stoichiometric amounts of nitrogen gas and hydrogen gas react in a calorimeter to produce 5.00 g of ammonia gas. the calorimeter temperature rises 0.42ác. the calorimeter and water have a combined heat capacity of 32.16 kj/k. calculate the heat of formation of ammonia, _háf, in kj/mol. the formation reaction for ammonia is: 0.5n2(g) + 1.5h2(g) _ nh3(g).

b. the decimal could be two-tenths.

step-by-step explanation:

a4 - 3a2 - 1

step-by-step explanation:

step   1   :

equation at the end of step   1   :

  ((a4) -   3a2) -   1

step   2   :

trying to factor by splitting the middle term

2.1     factoring   a4-3a2-1  

the first term is,   a4   its coefficient is   1 .

the middle term is,   -3a2   its coefficient is   -3 .

the last term, "the constant", is   -1
