Answer:
6. C3H2O
Explanation:
C= 12.0107; H= 1.00797; O=15.9994
We calculate:
C= 65.85/12.01=5.48
H= 4.91/1.00=4.91
O=29.24/16.00= 1.82
Later, we divide among the smaller quantity
C=5.48/1.82= 3.01
H=4.91/1.82= 2.70
O=1.82/1.82=1
Answer:
D
Explanation:
Sugar will dissolve faster when you stir the solution quickly because the act of stirring increases kinetic energy which increases the temperature.
Given what we know, we can confirm that John Dalton was the first person to show strong empirical evidence for the existence of atoms.
<h3>Who was John Dalton?</h3>
- He was a renowned scientist with knowledge in many fields.
- He was known to be a chemist, meteorologist, and physicist.
- He proposed the atomic theory and carried out experiments to provide supporting evidence.
Therefore, given his proposal of the atomic theory and the experiments he carried out to provide evidence to support his claims, we can confirm that John Dalton was the first person to show strong empirical evidence for the existence of atoms.
