What is the theoretical yield of sodium oxide (Na₂O) in grams when 20.0g of calcium oxide (CaO) reacts with an excess amount of
ad-work [718]

Answer:

22.1g

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

CaO + 2NaCl —> Na2O + CaCl2

Next, we shall determine the mass of CaO that reacted and the mass of Na2O produced from the balanced equation.

This is illustrated below:

Molar mass of CaO = 40 + 16 = 56g/mol

Mass of CaO from the balanced equation = 1 x 56 = 56g

Molar mass of Na2O = (23x2) + 16 = 62g/mol

Mass of Na2O from the balanced equation = 1 x 62 = 62g

From the balanced equation above,

56g of CaO reacted to produce 62g of Na2O.

Finally, we can determine the theoretical yield of Na2O as follow:

From the balanced equation above,

56g of CaO reacted to produce 62g of Na2O.

Therefore, 20g of CaO will react to produce = (20 x 62)/56 = 22.1g of Na2O.

Therefore, the theoretical yield of Na2O is 22.1g

What is the volume of a rock that has a mass of 50 grams and a density of<br> 5 g/ml?
Brut [27]

Explanation:

density = mass/ volume

so,

volume = mass/ density

volume = 50 g/ 5 g/ml³

volume = 10 ml³

Which of the following elements has 3 electrons in the outermost d orbital?
Nina [5.8K]

Answer:

A

Explanation:

Element A has 3 electrons in outermost shell so its valency is 3. It will loose 3 electrons to attain stability, as loss of 3 electrons is easier than gain of 5 electrons.

Valency of B is −2 as it will gain 2 electrons to attain stability and combine with other atom.

Valency of A⟶+3

Valency of B⟶−2

(Refer to Image)

Cross multiply valency of A and B

∴A2B3 compound will be formed.
