Question

Predict the Products and Balance the following equation: NaCl + MgO ->

Also, I need the name of the reaction occurring.

Answer 1

In this case, you would start by finding the charges of all of the reagents.

Na is +1, Cl is -1, Mg is +2, and O is -2.

Na and Mg won't combine, as they both have positive charges. Likewise, Cl and O won't combine because they are both negatively charged.

Dissociation is unlikely because the solvent hasn't been mentioned, meaning it will not play a role. Therefore, the products will likely be Na2O and MgCl2

Given that you have 2 Na and 2 Cl on the right side, and only 1 on the left, you know you need to have a coefficient of 2 on the left side.

2NaCl + MgO -> Na2O + MgCl2

Of the four kinds of chemical reactions (synthesis, decomposition, single displacement, and double displacement), which one do you think this is?
