How many atoms of hydrogens are found in 3.21 mol of
C3H8?

What neutral atom is isoelectronic to mn+4

Using a value of ksp = 1.8 x 10-2 for the reaction pbcl2 pb+2(aq) + 2cl -(aq). if the value of ksp was determined to be only 1.2 x 10-2: too much solid has dissolved. additional precipitate is forming. the solution is unsaturated. the ions are now combining to reduce their concentrations.

Acompound has the molecular formula c3h8. which class of organic compounds does it belong to?
