A student synthesized a coordination compound, Ni(NH3)nCl2, using the procedures given in the laboratory class. The student added 32.0 mL of 0.50 M HCl solution to an aqueous solution containing 0.2346 g of Ni(NH3)nCl2. The excess HCl required 25.60 mL of 0.1000 M NaOH solution for complete titration. How many moles of NH3 were present in the student's sample

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.
