Several acids are listed here with their respective equi- librium constants. hf(aq) + h2o(l) uv h3o+(aq) + f−(aq) ka = 7.2 × 10−4 hpo42−(aq) + h2o(l) uv h3o+(aq) + po43−(aq) ka = 3.6 × 10−13 ch3co2h(aq) + h2o(l) uv h3o+(aq) + ch3co2−(aq) ka = 1.8 × 10−5 (a) which is the strongest acid? which is the weakest acid? (b) what is the conjugate base of the acid hf? (c) which acid has the weakest conjugate base? (d) which acid has the strongest conjugate base?

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.
