Use the information given below to calculate the enthalpy change for the reaction: C2H4(g) + H2O(g) → C2H5OH(l)

Rxn 1 H2O(l) → H2O(g) ΔH1 = +44 kJ/mol

Rxn 2 C2H5OH(l) + 3O2(g) → 2CO2(g) + 3H2O(l)

ΔH2 = −1371 kJ/mol

3O2(g) → 2CO2(g) + 3H2O(l)

ΔH2 = −1371 kJ/mol C2H5OH(l)

Rxn 3 C2H4(g) + 3O2(g) → 2CO2(g) + 2H2O(l)

ΔH3 = −1409 kJ

the major pests we deal with are insects, weeds and fungal diseases. a pesticide is a product, whether organic or chemical, used to kill the target pest. there are other techniques gardeners should use that can prevent the severe infestations that make the use of pesticides necessary

the answer is 303.15 or 303

the answer is:  

line graphs show patterns in data with variables that change over time; whereas, circle graphs show data as parts out of a whole (such as out of 100%).
