Pure ethylenediamine(ED), H2NCH2CH2NH2 , is a liquid with a density of 0.896 g/ml. What mass of this compound would be needed to prepare 1.00 liter of a 0.030 M solution

You may expect bonds between two atoms which each have n covalent lonic metallic hydrogen

Name the intersection of plane bpq and plane cpq.

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.
