If a 0.075gram sample of a weak acid is dissolved in a 30-mL aqueous solution and then 10.0mL of the solution is used in the titration, how many grams of the sample are used for the titration?Show all work.

How many moles of al3+ ions are in 1.25 moles of al2o3

Astudent reacts 13 moles of iron with 21 moles of oxygen according to the following equation:

According to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? view available hint(s) according to the valence shell electron pair repulsion (vsepr) theory, a molecule that has four electron groups around the central atom will exhibit what electron geometry? trigonal bipyramidal tetrahedral square planar determination of electron geometry requires information on whether the electron groups are lone pairs or bonding groups.
