From the following heats of combustion, CH3OH(l) + 3 2 O2(g) → CO2(g) + 2H2O(l) ΔH o rxn = −726.4 kJ/mol C(graphite) + O2(g) → CO2(g) ΔH o rxn = −393.5 kJ/mol H2(g) + 1 2 O2(g) → H2O(l) ΔH o rxn = −285.8 kJ/mol Calculate the enthalpy of formation of methanol (CH3OH) from its elements: C(graphite) + 2H2(g) + 1 2 O2(g) → CH3OH(l) kJ/mol

What is the compound name for the formula [ru(en)2cl2]2+ and [co(en)cl2br]-

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.
