Evaporation loses of water in irrigation ditch (30 pts) water at 25°c is flowing in a covered irrigation ditch below ground. every 150 ft there is a vent 1.0 in inside diameter and 10 ft long to the outside atmosphere at 30°c. there are 15 vents in total. the outside air can be assumed to be dry. calculate the total evaporation loss of water in ib/day.

Joe shines white light into a bowl half full of water at an angle of incident of 27.5°. calculate the angle of refraction in the water given the indices of refraction for air and water are 1.00 and 1.36, respectively.

What’s the theoretical yield of solid lead

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?
