Answer:
there are 3 different elements in that equation
Explanation:
Fe is the element Iron, Cr is the element Chromium, and O is oxygen
Answer: D) It has two more electrons than protons.
Explanation: Sulphur (S) is an element with atomic number 16 and thus contains 16 electrons. A neutral atom contains equal number of protons and electrons.
![S:16:[Ne]3s^23p^4](https://tex.z-dn.net/?f=S%3A16%3A%5BNe%5D3s%5E23p%5E4)
An atom on losing electrons gains positive charge and on gaining electrons gain negative charge.
Sulphide ion 
is formed by gaining 2 electrons to attain stable configuration of argon and thus contains two more electrons than protons.

Answer:
Anaphase
Explanation:
Two separate classes of movements occur during anaphase. During the first part of anaphase, the kinetochore microtubules shorten, and the chromosomes move toward the spindle poles. During the second part of anaphase, the spindle poles separate as the non-kinetochore microtubules move past each other.
