Answer:
Ca(OH)2 (aq)
Explanation:
The balanced neutralization reaction i.e. a reaction between an acid and a base, in this question is given as follows:
H2SO4(aq) + Ca(OH)2(aq) → CaSO4(aq) + 2H2O(l)
According to Arrhenius in his definition of acid and base, a base is a substance that dissociates into hydroxide ions (OH-) when in an aqueous solution. In other words, a base increases the concentration of hydroxide ions when dissolved.
In this reaction, Ca(OH)2 releases the OH- (hydroxide ion) that combines with the hydrogen ion (H+) released by the acid, H2SO4, to form water (H2O). Hence, Ca(OH)2 (aq) is the BASE.
Answer:
8 possible combinations
Explanation:
In a diploid organism (2n), there are two sets of chromosomes in each cell. Each set of chromosome is contributed by each parent i.e one set of chromosome from the father and one set from the mother.
To determine the number of possible combinations in each gamete of a cell, we use the formula 2^n, where n = number of chromosomes in haploid gametes. In this case, the cell contains 3 pairs of chromosomes, meaning that each gamete will have 3 chromosomes. However, there will be 2³ = 8 possible combinations of chromosomes in each gametes.
About 2.5 % I think maybe if your talking about fresh water
