The values are given in the table below

substance δh°f (kj/mol)
so2 (g) −297
so3 (g) −396
so2cl2 (g) −364
h2so4 (ℓ) −814
h2o (ℓ) −286

the value of δh° for the following reaction is −62.1 kj. what is the value of δh°f for hcl(g)?

so2cl2(g) + 2 h2o(ℓ)→ h2so4(ℓ) + 2 hcl(g)

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.
