Answer:
Darwin's book introduced the scientific theory that populations evolve over the course of generations through a process of natural selection. It presented a body of evidence that the diversity of life arose by common descent through a branching pattern of evolution.
Explanation:
molarity = no. of moles of solute/solution in litres
5.1M=no. of moles of solute/7.3
5.1×7.3=no. of moles of solute
37.2 mol =no. of moles
Mass =70 ( Mass of protons=1 ,Mass of neutrons =1, Mass of electron =0.0005(can be ignored))
Therefore, 40 +30=70
Charge= -2 ( it is taking in/attracting electrons to its shell) base on the proton number you are able to identify if it is attracting or releasing an electron, if the electron number is more than proton number then it is attracting therefore resulting in a negative charge vice versa for releasing an electron.
White gold is yellow gold that has had other alloys added to it to make it appear white. New polished white gold has a bright white metal color. Depending of the type of alloys used in the fabrication of white gold, white gold jewelry tends to have a faint yellowish tint with wear.
The simplest ratios compare only two values, but ratios comparing three or more values are also possible. In any situations in which two or more distinct numbers or quantities are being compared, ratios are applicable. By describing quantities in relation to each other, they explain how chemical formulas can be duplicated or recipes in the kitchen expanded.
