Hello! Your answer would be a gain of electrons and a decrease in positive charge.
Contrary to how it sounds, reduction is actually a gain of electrons. It is part of a set of reactions known as a redox reaction, reduction being a gain of electrons and oxidation being a loss.
With the gain of electrons, the element would become more negative as electrons bring with them a negative charge. Therefore, this would decrease the positive charge.
Hope this helped!
Carbon tetra chloride = CCl4
calcium bromide = CaBr2
<u>Given:</u>
The number of particles = 3.131 * 10²⁴
<u>To determine:</u>
The number of moles corresponding to the given particles
<u>Explanation:</u>
1 mole corresponds to Avogadro's number of particles = 6.023 * 10²³ particles
Therefore, the given particles would correspond to:
3.131* 10²⁴ particles * 1 moles/6.023 * 10²³ particles = 5.199 moles
Ans: A) 5.199 moles are contained in 3.131* 10²⁴ particles
