A 6.70-g sample consisting of a mixture of silver nitrate and sodium ni- trate is dissolved in water. This aqueous mixture then reacts with aqueous barium chlo-
ride to form 3.60 g of silver chloride Calculate the percent by mass of silver nitrate in
the first mixture

Displacement is the slope of a velocity vs. time graph a. true b. false

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.
