2) Calculate the mass (actual yield) of product that can be prepared from 38.75 g of aluminum and 25.83 g of oxygen with a 78.5 % yield. Al + 02 -> Al2O3 (unbalanced)

3) in peaches, [oh]=3.16x10-11 m a) find [h+ ] b) what is the ph? c) is the solution acidic, basic, or neutral?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.

Answer explain why it is not possible to deduce a complete order of reactivity.
