Answer:
The net ionic equation will be MgCl₂ + 2 NaOH → Mg(OH)₂ + 2 NaCl
Explanation:
Ionization of MgCl₂ is as follows
MgCl₂ → Mg²⁺ + 2 Cl⁻
Ionization of NaOH is as follows
NaOH → Na⁺ + OH⁻
It is a one type of substitution reaction where OH⁻ combined with Mg²⁺ to give magnesium hydroxide .
On the other hand Cl⁻ combined with Na⁺ to give sodium chloride as product.
Using proper stoichiometry to balanced the number of atoms in both side .
The correct answer for, An element with the smallest anionic (negative-ionic) radius would be found on the periodic table in, is <span>Group 17, Period 2.</span>
Hello!
<span>
You'll need to react
7,5 moles of Sodium with sulfuric acid to produce 3.75 moles of sodium sulfate
</span>
First of all, you need to balance the reaction. The balanced reaction is shown below (ensuring that the Law of Conservation of Mass is met on both sides):
2Na + H₂SO₄ → Na₂SO₄ + H₂
Now, all that you have to do is to use molar equivalences in this reaction applying the coefficients to calculate the moles of Sodium that you'll need:
Have a nice day!
