Answer 1

@DarrenMadx

Answer 2

the smallest particle of an element still having the characteristics of that element

Answer 3

John Dalton determined that the concept of atoms could be used to describe matter.

In the 1800s, John Dalton, an English scientist, came up with an atomic theory of matter. Here are four points that are the cornerstone of his theory:

All matter is made up of atoms.
Atoms are very small, indivisible, indestructible particles.
All atoms of a given element are identical in mass and other properties.
Chemical compounds form when two or more kinds of atoms combine.
Dalton suggested that chemical reactions happen when atoms combine, separate, or rearrange, but the atoms themselves do not change identity in the process.

Answer 4

where did you get that from. there is no way you typed that so fast

Answer 5

:)

Answer 6

so your not going to cite where you got that from?

Answer 15

Answer 16

1. In 1912, chemist Fritz Haber developed a process that combined nitrogen from the air with hydrogen at high temperatures and pressures to make ammonia. Specifically, the process involved combining one molecule of nitrogen gas (N2) with three molecules of hydrogen gas (H2) to get two molecules of ammonia (NH3). If you write this process in a symbol format, it looks like this:
N2 + 3H2 → 2NH3

Explain whether this is a chemical or physical change, and why. Does it involve elements, compounds, mixtures, or pure substances? Also describe how many atoms are involved before and after. What do you notice about the number of atoms?
Answer:
Could you pretty please help me @DarrenMadx

Answer 17

I'm sooo confused :(

Answer 18
