C, when mammals reproduce, the father and mother will both have traits that get carried over to the child.
Mole ratio is the ratio between the amount in moles of any two compounds involved in a chemical reaction
3
the mole of Fe3O4 is 1 mole while that of Fe is 3 moles from the reacting equation below
Fe + 4 H2O ----> Fe3O4 + 4 H2
therefore the mole ratio of Fe3O4 to Fe is 1:3(answer A)
7. Neutralisation. Which would (obviously) appear GREEN on the chart.
Chlorine-36 has been widely used for dating old groundwater.
