Juliana was late to physical science class and missed the beginning of the notes, including the title. these are the notes she took. -makes up everything -can be solid, liquid, or gas -is made up of atoms, or tiny particles that are the smallest unit of matter what would be the best title for her notes? atoms matter mass weight

Answer is: matter.

Dalton said that matter is composed of atoms and atoms of different elements can join to form chemical compound.

There are four fundamental states of matter (gas, liquid, solid and plasma).

Mass is a fundamental measure of the amount of matter in the object. Kilogram (symbol: kg) is the base unit of mass in the International System of Units.  

The weight is the force of gravity on the matter. It is affected by gravity.

answer: enthalpy

explanation:

for a exothermic reaction, the energy is released i.e. the energy of the products is lower than the energy of the reactants.

= enthaply

= energy of products

= energy of reactants

as , thus comes out to be negative. negative value of enthalpy shows that the reaction is exothermic.
