One of the components of polluted air is NO. It is formed in the high-temperature environment of internal combustion engines by the following reaction:
N2(g) + O2(g) --> 2NO(g)
ΔH°= 180 kJ
Why are high temperatures needed to convert nitrogen and oxygen into nitrous oxide? Predict the entropy of the reaction.How much energy would be needed to react 10 grams of nitrogen in the presence of excess oxygen?
Determined if CS 2 of 2.500 grams mix with an excess of chlorine gas , 9.310 Kilo joule of heat is evolved. What sort of reaction is this , Is the reaction exotermic also find out delta H for the reaction?
Calculate the heat released when 156 g of water at 23.0 degrees celcius is convered to ice at -10.0 degrees celcius
How many grams of IO2F are needed to react completely with 150.0 g of BrF3? 3IO2F(s) + 4BrF3(l) → 3IF5(l) + 2Br2(l) + 3O2(g)
