Estimation of Vmax and Km by Inspection Although graphical methods are available for accurate determination of the Vmax and Km of an enzyme-catalyzed reaction, sometimes these quantities can be quickly estimated by inspecting values of V0 at increasing [S].
Estimate the Vmax and Km of the enzyme-catalyzed reaction for which the following data were obtained.

[S], (M) v0= μ m/min=initial rate
2.5 x 10^(-6) 28
4.0 x 10^(-6) 40
1 x10^(-5) 70
2 x 10^(-5) 95
4 x 10^(-5) 112
1 x 10^(-4) 128
2 x 10^(-3) 139
1 x 10^(-2) 140

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?
