Which statement is false? A) Solar energy can be converted from solar radiation energy, to heat energy, to electrical energy and kinetic energy.

B) Wind energy originally came from the sun because solar radiation changes atmospheric temperature, which changes air pressure, causing wind used for wind energy.

C) Geothermal energy is NOT considered a fossil fuel.

D)Energy from the combustion of gas is cleaner because it does not produce greenhouse gases like carbon dioxide and water.

For a research project, a student decided to test the effect of the lead(ii) ion (pb2+) on the ability of salmon eggs to hatch. this ion was obtainable from the water‐soluble salt, lead(ii) nitrate, which the student decided to make by the following reaction. pbo(s) + 2 hno3(aq) → pb(no3)2(aq) + h2o losses of product for various reasons were expected, and a yield of 86.0% was expected. in order to have 5.00 g of product at this yield, how many grams of pbo should be reacted? (assume that sufficient nitric acid, hno3, would be used.)

When hydrogen peroxide (h2o2) is added to potassium iodide (ki) solution, the hydrogen peroxide decomposes into water (h2o) and oxygen (o2). the chemical equation for the decomposition reaction is: 2h2o2—> 2h2o + o2. what is the role of the potassium iodide in this reaction? a. reactant. b. product. c. precipitate. d. catalyst.
