A brewery has a horizontal conveyor belt to transfer malted barley from a storage silo to the mash tun (the large vessel where the malted barley is steeped in hot water). The conveyor belt is composed of scoops that each hold 4.50 lb of malted barley and are separated by a distance of 14.0 inches on the belt. If 5.500 × 103 lb of malted barley is added to 2063 gallons of water in 4.75 min, what is the rate at which kinetic energy is transported into the mash tun by the conveyor belt?
If 1.50 g of (NH4)2SO4 is dissolved in enough water to form 200. mL of solution, what is the molarity of the solution.
sulfur dioxide is an unwelcome result of burning soft coal in power plants. Some of the sulfur dioxide ends up as sulfuric acid ( H2SO4) in acid rain.
Determine the molar concentration of chloride ions after adding 225 ml of 0.625 MKCL with 615 ml of 0.385M MgCl2 if final volume of the solution is 840ml.
Given the balanced equation: C2H4 + 3O2 → 2CO2 + 2H2O How many liters of CO2 are produced when 15 liters of O2 are consumed?
what is the total number of joules of heat energy absorbed when the temperature if 200.0g of water is raised from 10 degrees celcius to 40 degrees celcius.
Aspirin (C9H8O4) is produced through the following reaction of salicylic acid (C7H6O3) and acetic anhydride (C4H6O3). C7H6O3(s) + C4H6O3-> C9H8O4(s) + HC2H3O2
