You will be given a 2% Reducing Sugar solution, and a separate Reducing Sugar solution with an unknown concentration. Design an experiment with your partner that will allow you to determine the concentration of that unknown solution using a spectrometer. Your design should include a clear research plan and a detailed set of procedures that you will follow in your experiment.

Ajet plane is speeding down the runway during takeoff. air resistance is not negligible. identify the forces on the jet.

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?
