Wasses Fill in the calculation triangle for changing between masses and moles. Then complete the table below. (Use the
following A values: H=1, C = 12, N = 14,0 = 16, Mg = 24, S = 32, CI = 35.5, Ca = 40, Cu = 64.)
Substance Ar or Mr number mole G
cu ? ? 128
some pls i dont understand that traingle how to fill i finded ar and mole gramm pls help me​

Nitric oxide (no) can be formed from nitrogen, hydrogen and oxygen in two steps. in the first step, nitrogen and hydrogen react to form ammonia: n2(g) + 2 h_2(g) rightarrow 2 nh_3 (g) delta h = -92. kj in the second step, ammonia and oxygen react to form nitric oxide and water: 4 nh_3(g) + 5 o_2(g) rightarrow 4no(g) + 6 h_2o(g) delta h = -905. kj calculate the net change in enthalpy for the formation of one mole of nitric oxide from nitrogen, hydrogen and oxygen from these reactions. round your answer to the nearest .
