When a metallic hydroxide is dissolved in water the hydroxide ion concentration depends upon the formula...
When a metallic hydroxide is dissolved in water the hydroxide ion concentration depends upon the formula of the metallic hydroxide. When completely dissociated, the hydroxide ion concentration will be the concentration of the whole compound times the number of hydroxide ions units in the formula. 1. Calculate the concentration of hydroxide ions and hydronium ions in the following basic solutions: (a) A solution prepared by dissolving 200 g of magnesium hydroxide in enough water to make 4.00 L of solution....

A beam of monochromatic light passes from air to water (n = 1.33) to glass (n = ?). The two interfaces are parallel to each other, and the angle of incidence in air is 26 degrees, and that in the glass is 18 degrees. What is the index of refraction of the glass? Keep 2digits after decimal point. Your answer should be formatted like: 0.00

A chemist prepares a solution..
A chemist prepares a solution of magnesium fluoride (MgF) by measuring out 0.00973 umol of magnesium fluoride into a 100. mL volumetric flask and filling the flask to the mark with water. Calculate the concentration in mmol/L of the chemist's magnesium fluoride solution. Be sure your answer has the correct number of significant digits. mmol x 6 ?

Air at l atm and 20°C is flowing over the top surface of a L=0.2 m × w=0.5 m-thin metal foil. The 7650 W/m 2. If the friction force on the metal foil surface is 0.3 N, determine the surface temperature of the metal foil. Evaluate the fluid properties (Table A-15) at the film temperature of 120°C. After finding the surface temperature, recalculate...
