A solution of ammonia has a pH of 11.8. What is the concentration of OH ions in the solution?
Useful formulas include [H301) - 10 OH-1 -10 POH, PH+pOH = 14, and [H3O+][0H) - 10-14

Is 9 correct? and can someone me with 10? it’s due tomorrow, you

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.
