Arrhenius is a substance that dissociates in water to produce hydrogen ions (H+) and there is a clear answer which coincides with this definition. The correct answer is definitely b. a substance that increases the concentration of hydronium ions when dissolved in water.
Answer:
13 chromosomes, meiosis
Explanation:
the sperm cell contributes half of the chromosome in an offspring while the egg cells contributes the other half. Hence, the sperm cell has half of 26, 13. This process is called meiosis. Meiosis is when one cell undergoes cell division twice, thus creating 4 new cells. Each of these 4 new cells have half the amount of chromosomes as the original cell.

Considering that the water is at atmospheric pressure, its density at 21°C is still about 0.99 g/mL. The volume of the water is calculated by dividing the given mass by the density. That is,
Volume = mass / density
Substituting the known values to the equation,
volume = 23.2243 grams/ 0.99 g/mL
Simplifying,
volume = 23.46 mL
<em>Answer: 23.46 mL</em>
