K forms the compound K2O , which is an ionic compound that is brittle. Identify another element, M , that is likely to form a br
meriva

The metal is sodium, Na.

<u>Explanation:</u>

K₂O is an ionic compound in which K is in the oxidation state of +1 and it belongs to group 1.

Group 1 elements also form oxides with the metals with the general formula M₂O and M being Na, K, Li and so on.

Metals Like sodium and Potassium are so brittle in nature and also their oxides.

So the other metal that form metal oxide which is brittle as well as ionic in nature, and so the metal oxide is Na₂O.

So the metal is sodium, Na.

Which type of reactions form salts?
s344n2d4d5 [400]

Neutralization reactions are the reactions type which form salts.

Explanation:

Salts are formed by ionic bonds when the oxidation states of anions and cations are equal and have opposite signs. So one should be highly electronegative in nature and another should be highly electropositive in nature. So the electropositive element will be ready to give electrons and the electronegative element will be ready to accept all the electrons given by the electropositive element. As a whole the compound will be neutrally charged by adding of equal number of positively charged and negatively charged ions.

The reduction or addition of electrons will be occurring in cations and the oxidation or removal of electrons will be occurring in anions.

So the salt formation is based on neutralization reactions.

When adding or subtracting deelmals, how many digits should the answer contain?
Alexus [3.1K]

Answer:

Depends, but in most cases, 2.

It's best to use as many digits as possible to keep it accurate.

Explanation:

This varies between teachers, as most schools go with 2 decimal places.

This is something that depends in your situation.

You technically want as many decimals as possible to keep it as accurate, but most people stick with 2.

I personally do 3, and commonly do 5 sometimes.
