A student believes that a sample of solid CaCl2 may be contaminated with KNO3(3). Knowing that pure CaCl (s) contains 64% chlorine by mass, the student performs an experiment to determine the mass
percent of chlorine in the sample of CaCl2 (3)
Which of the following results for the mass percent would best support the student's claim that the
sample of CaCl (s) is contaminated with KNO3(s)?​

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.
