In the reaction: AlCl3 (aq) + 4 NaOH (aq) → NaAlO2 (aq) + 3 NaCl (aq) + 2 H2O (l) a. How many moles of sodium hydroxide will react with 125 grams of aluminum chloride? (3.75)

b. How many moles of water are produced when 56 grams of sodium hydroxide react with excess aluminum chloride? (0.70)

c. How many moles of sodium hydroxide are needed to produce 500 grams of sodium chloride? (11.4)

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.
