False because the atoms are what helps the liquid in the container
B. The element nitrogen is made up only of nitrogen atoms.
Explanation:
Dalton stipulated , in his theory, that all the atoms of pure elements were identical. However different elements had different kinds of atoms that differ in their size and mass. The other stipulations of Dalton's theory were that atoms are the smallest unit of mass and were indivisible – this was later rebutted by advanced atomic theories .
Another major contribution by Dalton's theory is that chemical reactions involved the rearrangement of atoms observing the law of conservation of mass,
I think its <span>173.34168 g/mol</span>
M1V1 = M2V2
37.5 mL * 0.245M = 18.0 mL * x M
(37.5*0.245)/18 = x M
x = 0.510
0.510 M is the answer.
Explanation:
chemical to add to swimming pools in order
to make the water safer. She mixed two solid
substances together in a sealed container.
The diagram above shows the repeating
groups of atoms that make up the two
starting substances.
After mixing, Tiana found two liquid
substances in the sealed container.
(Nothing had escaped.) Which of the
diagrams to the left shows the repeating
groups of atoms that make up the ending
substances?
