Hi help me pls I don't know how to do this

O - Oxide

N - Nitride

Cl - Chloride

Br - Bromide

Sulfide - S^2-

Iodide - I^-

Phosphide - P^3-

Flouride - F^-

When you have a non-metal, it ends in -ide when you place it into a chemical bond. These are all diatomic molecules (apart from phosphorus) and as such you take the element name, remove the suffix, and add -ide. When converting back, look at the electronegativity levels on your periodic table in the upper right corner of each element. (if you don't have them, google "nyc regents chemistry reference table" and go to page 6 of the first result.) The first charge in that spot is what the charge will be.

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

the answer is yes

it has kinetic energy

reason

an object has kinetic energy when you stop the force carrying it, the object will stay in motion.

hope this contact me for more questions if you'd like: )
