Answer:
The answer to your question is:
Explanation:
Data
Ion charge of 2- and 18 electrons
Process
a) From which atom does this ion form?
If an Ion has a negative charge, it means that it has more electrons than the neutral atom. So, it the ion has 18 electrons, it means the neutral atom has 16 electrons.
In the periodic table we find that the atom with 16 electrons is Sulfur.
B) How do you know?
I have explained it.
An ion with a negative charge means that it gained the number of negative charges compare with the neutral atom.
Answer:
Li (s) + H₂O (l) → 1/2 H₂ (g) + LiOH (aq)
Explanation:
Lithium metal reacts with liquid water to form hydrogen gas and aqueous lithium hydroxide
2Li (s) + 2H₂O (l) → H₂ (g) + 2LiOH (aq)
We can divide stoichiometry coefficients /2, to have the lowest stoichiometry.
Greater amplitude waves have more energy and greater intensity, so they sound louder. ... The same amount of energy is spread over a greater area, so the intensity and loudness of the sound is less. This explains why even loud sounds fade away as you move farther from the source.
Answer:
It is important to analyze data to further understand what's going on. By analyzing data, you know more about what you are investigating. Without analyzing data, you may find it harder to figure something.
