When the amount of energy required to break bonds in the reactants is less than the amount of energy released in forming bonds in the products, the process has a negative change in enthalpy (−δh). true false

the enthalpy of a reaction is calculated from the following formula

ΔHrxn = ∑ΔHf(products)-∑ΔHf(reactants)

Now its clear from the formula that if

a) the enthalpy of products will be more than the reaction enthalpy will be positive [endothermic reaction]

b) the enthalpy of products will be less than the reaction enthalpy will be negative [exothermic reaction]

Also

ΔHrxn = ∑Bond energies of reactants - ∑Bond energies of products

So

if bond energy of reactants [the energy required to break bond] is less than the bond energy of products the enthalpy of reaction will be negative.

the food using pesticides in the future will harm you by giving you diseases like cancer or something since they have things that we should not eat in it like chemicals or pesticides. that is why organic food is more expensive because they take the time to make it right and healthy for you to eat.

explanation:

the answer is 1260

you spend 7 hours in school for 1 school day with 5 school days in 1 school week with 36 school weeks in a school year.

7*5*36= 1260 it's all about multiplying
