Sodium hydride racts with excess water to produce
aqueoussodium hydroxide and hydrogen gas. what mass (in grams) of
sodiumhydride will produce 982 ml of gas at 28.0 c and 765 torr,
when thehydrogen fas is collected above water? the vapor pressure
of waterat this experiment is 28 torr.

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.
