A single wind turbine has a maximum power output of 2 000 000 W. The wind turbine operated continuously at maximum power for 6 hours. Calculate the energy output in kilowatt-hours of the wind turbine.

Equation: P = Wt (Power = Work[Energy] x time)1) Convert Watts to Kilowatts (W -> kW)2,000,000W -> 2,000kW [divide by 1000]2) Multiply work by time (remembering the question asks for kWh)2,000kW x 6h =...

How do you make calcium hydroxide (Ca(OH)2) from Calcium carbonate (CaCO3) and what are the equations.

Thermally decompose the calcium carbonate:CaCO 3 -> CaO + CO 2 Now mix the CaO with water:CaO + H 2 O -> Ca(OH) 2
