Suppose that CaO is added as an impurity to Li2O. If the Ca2+ substitutes for Li+, what kind of vacancies would you expect to fo

rm? How many of these vacancies are created for every Ca2+ added? Group of answer choices Positive charges are eliminated by creating lithium vacancies, and for every Ca2+ ion added, a single lithium vacancy is formed. Positive charges are eliminated by creating calcium vacancies, and for every Ca2+ ion added, a single calcium vacancy is formed. Positive charges are eliminated by creating lithium vacancies, and for every Li+ ion added, a single lithium vacancy is formed.

Answer:

Positive charges are eliminated by creating lithium vacancies, and for every Ca2+ ion added, a single lithium vacancy is formed.

Explanation:

The addition of calcium oxide as an impurity to lithium oxide creates an  interstices due to the replacement of the Lithium ion by calcium ion. The creation of  interstices is as a result of  the replacement of the positive ions (Lithium by calcium). To make the reaction neutral, these replacements must occur  when the interstices are formed

Consider the complete reaction of 43.0 g of silicon with excess nitrogen gas in the reaction shown below. What mass of product f
kupik [55]
The answer to your question is : no.of moles of Si = 43/atomic mass of Si = 43/28.1 = 1.53

according to reaction 3 moles of Si gives 1 mole of Si3N4

so 1.53 mole of Si will give 1.53/3 = 0.51 mole of Si3N4

molar mass of Si3N4 = 140.28 g/mole

it means that 1 mole of Si3N4 = 140.28 g

so 0.51 mole of Si3N4 = 0.51 X 140.28 = 71.543 g

A 500 gram price of metal has a volume of 2.75. What is the density
Oxana [17]
Density of an object is computed by dividing its mass by its volume. D = M / V

Solution:
D = 500 g / 2.75 cm3
D = 181.82 g/cm3

Further, density of an object is computed by dividing its mass by its volume. D = M / V

 However, since Volume is the missing component in the equation. Mass of an object is divided by its density to get its volume. V = M / D

<span>Volume of Gold nugget          = 50 g </span>/<span> 19.3g/cm3  = </span>2.59cm3
<span>Volume of Iron Pyrite nugget = 50 g </span>/ <span>5.0g/cm3    = </span>10cm3
