Carbon-12 contains 6 protons and 6 neutrons. the radius of the nucleus is approximately 2.7 fm (femtometers)? and the radius of the atom is approximately 70 pm (picometers). calculate the volume of the nucleus and the volume of the atom. (assume two significant figures.) and also what percentage of the carbon atom's volume is occupied by the nucleus? (assume two significant figures.)

Which is a characteristic of mixtures?

Determine the empirical formula for succinic acid that is composed of 40.60% carbon, 5.18% hydrogen, and 54.22% oxygen.

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.
