Brainlies ! 1. which of the following indicates that an endothermic reaction has occurred? heat is released water is formed salt is produced temperature decreases 2. scientists have developed a new drug known to cure a previously incurable disease. what best explains if the new drug is a compound or not? it is a compound because it will be able to cure a disease. it is not a compound because it was developed by scientists. it is a compound because compounds make all types of matter. it is not a compound because compounds make up only living things.

1st of all, the hey neighbor guy is way off, you can google it. Part 1 the answer is D: Temperature decreases. i dont know part 2 but do not listen to the other guy for part one.

answer: i don't know

explanation:

you need to provide a picture, otherwise i can't tell you.

if you can provide one, i'd be more than happy to you with this!

the relative atomic mass of an element is the mass of one atom of that element, relative to 1/12th of the mass of a  1212c atom. to convert to an absolute mass in kg, it is necessary to multiply by  1.661×10−271.661×10−27.

the relative atomic mass is roughly equal to the number of neutrons, plus the number of protons, in the nucleus of the atom.

for elements with more than one stable isotope (different types of nucleus with different numbers of neutrons but the same number of protons), the quoted mass is usually the average mass, weighted by the relative abundance of the different isotopes.
