You have a buffer with a ph-5 at two different temperatures: t-300 k and t2 330 k ha(aq) + h2o a) → a-(aq) + h3o+ (aq) you need to have the following ratios of weak acid and conjugate base to make this happen: at t1 → [a-]/[ha-1/2 at t2- [a-1/[ha] 1/4 to answer the following questions you need to draw the plot of inkverses 1/t will this reaction be exothermic, endothermic or neither. a. exothernue b. the system entropy change will be: circle one: as > 0 as = 0 < 0

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.
