Moles Pbl2 =  0.8628 g  :  461.01 g/mol   = 0.001871

moles I = 2 x  0.001871 = 0.003742

[I-] = 0.003742/ 0.0429

= 0.0872 M

Explain how a hydroelectric power plant converts energy stored in water into electricity
mart [117]
Hot water, as in very hot water, goes to steam with an enormous change in volume and pressure. This is capable of driving turbine blades, which in turn rotate enormous copper (eg) wired coils in enormous magnetic fields. This in turn produces electricity via electromagnetic induction and Fleming's right hand (I think it is) DYNAMO rule. That goes down miles and mile of v heavy conducting wire/cable as electricity.

What property is primarily responsible for determining the type of electromagnetic energy and peak wavelength emitted by a star
Galina-37 [17]

Answer:<u><em>B. Temperature</em></u>

Explanation:The temperature of the star such as Sun is measured. Using this measurement, its peak wavelength and energy can be determined.For determination of wavelength, <u>Wien's displacement law is used</u>. This law states that, the sun like body emits all kinds of wavelengths and thus is nearly a black body.For black body, the peak wavelength emitted is inversely proportional to the temperature of the body. From the wavelength, energy can be calculated.<u>Temperature is the property which is primarily responsible for determining the type of electromagnetic energy and peak wavelength emitted by star</u>.
