Use the following reaction: 4Fe + 3O2 → 2Fe2O3

If you have 6.8 mol of Fe, how much Fe2O3 (in moles) would you make?

100mg magnesium reacts with 20ml of 1.0m hcl

The is a particle with one unit of positive charge a. proton b. positron c. electron d. nucleus awnser quick it is a important science test!

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.
