Sulfurous acid is a weak diprotic acid and its protons are lost one at a time. Write the dissociation reactions and calculate the pH of 0.502 M H2SO3 and [SO32- ] of this solution. (Ka1= 6.9 E4, Ka2 = 4.3 E-7)

What is the mass of 0.46 mol of mgcl2

Which statement best describes the he properties of iconic compounds ?

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.
