Because it is balanced with protons and electrons
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.

Answer:
After the full moon (maximum illumination), the light continually decreases. So the waning gibbous phase occurs next. Following the third quarter is the waning crescent, which wanes until the light is completely gone -- a new moon.
Explanation:
Answer:
2HNO3 + Ca(OH)2 → 2H2O + Ca(NO3)2
Explanation:
HNO3 + Ca(OH)2 → ?
This is an acid-base reaction. It is also a double displacement reaction, in which the positive ions change partners.
Thus, H pairs with OH and Ca pairs with NO3.
HNO3 + Ca(OH)2 → HOH + Ca(NO3)2
HOH is our old friend, H2O (water) so, after balancing atoms, the equation becomes:
2HNO3 + Ca(OH)2 → 2H2O + Ca(NO3)2
