Which statement regarding the relative energies of monochromatic light with with λ = 800 nm andmonochromatic light with λ = 400 nm is correct? (a) 800 nm light has half as much energy per mole of photons as 400 nm light.(b) 800 nm light has the same energy per mole of photons as 400 nm light.(c) 800 nm light has twice as much energy per mole of photons as 400 nm light.(d) no conclusion may be drawn regarding the relative energy per mole of photons without knowing the intensity of the light.

For each of the following compounds, decide whether the compound's solubility in aqueous solution changes with ph. if the solubility does change, pick the ph at which you'd expect the highest solubility. you'll find ksp data in the aleks data tab. compounds does solubility change with ph

Draw the lewis dot structure for each of the following polyatomic ions

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.
