A mixture of acetone, ethanol, methanol, and acetaldehyde is to be separated using distillation. The boiling points of the components are as follows: acetone (CH3COCH3), 50.5∘C ethanol (CH3CH2OH), 78.4∘C methanol (CH3OH), 66∘C acetaldehyde (CH3CHO), 20.8∘C. Which compound would be expected to be the last component remaining in the still pot?

In an oxidation-reduction reaction, oxidation is what happens when a reactant

Cryolite, na3alf6(s), an ore used in the production of aluminum, can be synthesized using aluminum oxide. start this question by first balance the chemical equation.1.) balance the equation: - alo3(s)+naoh(l)+hf(> na3alf6+h2o(g). 2.) if 17.5 kilograms of al2o3(s), 51.4 kilograms of naoh(l), and 51.4 kilograms of hf(g) react completely, how many kilograms of cryolite will be produced? 3.)which reactants will be in excess, (al2o3, naoh, or hf) 4.)what is the total mass of the excess reactants left over after the reaction is complete in kg?
