Top fuel dragsters and funny cars burn nitromethane as fuel according to the balanced combustion equation: 2 ch3no2(l ) + 32o2( g)¡2 co2( g) + 3 h2o(l ) + n2( g) δh °rxn = -1418 kj the enthalpy of combustion for nitromethane is -709.2 kj>mol. calculate the standard enthalpy of formation (δh °f ) for nitromethane

idk what the question is about

1 is the answer to this problem

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.
