For each of the following pairs of substances, determine which has the larger molar entropy at 298 k: (a) br2(l) or (b) cl2(g) (c) ni(s) or (d) fe(s) (e) c2h6(g) or (f) c2h4(g) (g) ccl4(g) or (h) ch4(g) (i) hgo(s) or (j) mgo(s) (k) nacl(aq) or (l) mgcl2(aq) enter the six letters in order (e. g. acegik, bdfhjl, etc.)

What happens to energy in an open system?

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.
