Which statement about the reaction is correct? (1 point)
The reaction is endothermic because the total bond energy of the reactants is greater than the total bond energy of the products.
The reaction is endothermic because the energy of each bond in the reactants is less than the energy of a bond in the products.
The reaction is exothermic because the energy of each bond in the reactants is less than the energy of a bond in the products,
The reaction is exothermic because the total bond energy of the reactants is greater than the total bond energy of the products.

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

chemistry sucks a**

explanation:

i believe it is c.) 1575 j.

i would say b

explanation:

but i think i would need more information than that
