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.

A double replacement reaction can be best described as a reaction in which

<h3>Answer </h3>

Option C= ions are exchanged between two compounds.

<h3>Explanation </h3>

A double displacement reaction, also known as a double replacement reaction or metathesis, is a type of chemical reaction where two compounds react, and the positive ions (cation) and the negative ions (anion) of the two reactants switch places, forming two new compounds or products. For example,

                                    Na2S + 2HCl → H2S + 2NaCl

Option D is incorrect because electrons are exchanged between the atoms in oxidation –reduction reactions.

Which of the following is the correct wedge and dash conformation for the following Newman projection?
kakasveta [241]

We have that  the correct wedge and dash conformation for the following Newman projection is

IV

From the Diagrams above

Two CH_3 groups points on opposite sides in plane

Two Br are on same side  of plane

Two H also on same side of the plane so the plausible  structure is IV

Therefore

The Correct option is IV

A reaction produces 10.5 L if oxygen, but was supposed to produce 1 mol of oxygen. What is the percent yield ? (One mole of any
Rzqust [24]
To answer this item, we assume that oxygen behaves ideally such that it is able to fulfill the following equation,

 PV = nRT

If we are to retain constant the variable n and V. 

The percent yield can therefore be solved through the following calculation,

   n = (10.5 L)/(22.4 L)   x 100%

Simplifying,
    n = 46.875%

Answer: 48.87%
