Phosphorus can have a total of 4 oxidation states when it forms bonds with oxygen to become an oxyanion (+1, +3, +5, +7). The oxidation state of phosphorus increases by two with each additional oxygen atom in the formula unit. The two oxyanions of phosphorus shown in the table (PO33− and PO43−) correspond to the second lowest and second highest oxidation states of P. Consider the chemical formulas that would correspond to the oxyanions of phosphorus that are missing from the table of common polyatomic ions. What is the chemical formula of the oxyacid hypophosphorous acid?

Imagine that a new planet is discovered with two moons of equal mass: moon a and moon b. the mass of the new planet is greater than the combined mass of its moons. moon a is farther away from the new planet than moon b. what is the planet's gravitational pull on moon a compared to the planet's gravitational pull on moon b? the planet's gravity repels moon a with a greater force than it repels moon b, which is why moon a is farther away. the gravitational pull on moon b is greater than on moon a because moon b is closer to the new planet than moon a. the gravitational pull on moon b is greater than on moon a because moon b is farther away from the new planet than moon a. the gravitational pull on moon a is the same as the gravitational pull on moon b because distance does not affect the planet's gravity.
