Explanation:
The woman's father has haemophilia so his genotype must be XhY, so his daughter can only have the following genotype: XHXh. Her husband is not a haemophiliac so his genotype must be XHY. There is a 50% chance that the mother's gamete has the recessive allele for haemophilia. If she has a son that son will have a 50% chance of getting the Xh. This also applies to daughters, but they will get the normal allele XH from their father so the daughter will have a 0% chance of developing haemophilia.
First, we must represent the compounds into their condensed formula. The reactants would be Fe2O3 and H2, then the products would be Fe and H2O. Balancing the reaction, the overall reaction would look like this:
Fe2O3 + 3H2 = 2Fe + 3H2O
Thus, the coefficient for Hydrogen gas is 3.
