4 0
CaBr2(aq) is an ionic compound which will have the releasing of 2 Br⁻ ions ions in water for every molecule of CaBr2 that dissolves.
CaBr2(s) --> Ca+(aq) + 2 Br⁻(aq)
            [Br⁻] = 0.33 mol CaBr2/1L × 2 mol Br⁻ / 1 mol CaBr2 = 0.66 M
The answer to this question is [Br⁻] = 0.66 M

If we combine the reaction of an acid protonating water and the reaction of its conjugate base deprotonating water, the net reac
trasher [3.6K]

After eliminating common terms, the net reaction occurs when we combine the reactions of an acid protonating water and its conjugate base deprotonating water is<u> the autoionization of water.</u>

<h3>What is the autoionization of water?</h3>

The autoionization of water demonstrates that water can react with itself because acids and bases should interact with one another.

Here, the sound should be strange. Additionally, the water molecules should experience a small degree of proton exchange.

Thus, the correct option is c. The autoionization of water.

To learn more about the autoionization of water, refer to the below link:

Deprenyl is an enzyme inhibitor that helps prevent the metabolism of dopamine in the brain. The chemical formula of Deprenyl is
mel-nik [20]

Answer:

0.007 g of deprenyl dose is required fro the patient with body mass of 70 kilograms.

Explanation:

The dose for treating Parkinson’s disease = 100 μg/kg body weight

Mass of patient's body = 70 kg

Amount of dose of deprenyl required = 100 μg/kg × 70 kg = 7,000 μg

1 μg = 0.00001 g

7,000 μg = 7,000 × 0.000001 g = 0.007 g

0.007 g of deprenyl dose is required fro the patient with body mass of 70 kilograms.
