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

Determine the number of moles of H in each sample
MissTica

C. The number of moles of H in 0.109 mole of N₂H₄ is 0.436 mole

D. The number of moles of H in 34 moles of C₁₀H₂₂ is 748 moles

<h3>C. How to determine the number of mole of H in 0.109 mole of N₂H₄</h3>

1 mole of N₂H₄ contains 4 moles of H

Therefore,

0.109 mole of N₂H₄ will contain = 0.109 × 4 = 0.436 mole of H

<h3>D. How to determine the number of mole of H in 34 mole of C₁₀H₂₂</h3>

1 mole of C₁₀H₂₂ contains 22 moles of H

Therefore,

34 mole of C₁₀H₂₂ will contain = 34 × 22 = 748 mole of H

Shown below is a table with plants and animals with their adaptations.
zhenek [66]

Answer:

Desert

Explanation:

The adaptation shown by the given plants and animals shows that they will adapted to the desert biome.

It is so because, due to high temperature of desert some desert animals like camel have the storage of fat in humps or tails; some animals have large ears such as Jackrabbits, it helps to release body heat and adapt in high temperature; plants have thick water holding tissues to reduce water loss in heat and waxy coating that keeps  the plants cooler and reduce moisture loss.

Hence, the correct answer is "Desert".
