question: whats the formula for magnesium chloride with the valences balanced? answer options: select one of four mg+2cl-1₂ mgcl mg+2cl mgcl₂
Answer
Explanation:
Step1: Determine ion charges
Magnesium forms $Mg^{2 + }$ ion and chlorine forms $Cl^{-}$ ion.
Step2: Balance charges
To balance the +2 charge of magnesium, we need 2 chloride ions. So the formula is $MgCl_{2}$.
Answer:
D. $MgCl_{2}$
