Question 6(multiple choice worth 4 points) (08.06 mc) which of the following statements best compares geothermal energy and the energy from natural gas based on their rates of renewal? natural gas has a slower rate because any amount extracted is far lower than its generation inside earth. natural gas has a faster rate because, being a carbon resource, it quickly replenishes as part of the carbon cycle. geothermal energy has a faster rate because a vast amount of heat energy is always present inside earth's core. geothermal energy has a slower rate because the water present below earth's surface cools down periodically.

The content of manganese (mn) in steel was determined spectrophotometrically and with the use of the standard addition method. an unknown sample of mn from a digested steel sample gave an absorbance of 0.185 when analyzed spectrophotometrically. when 5.00 ml of solution containing 95.5 ppm mn was added to 50.0 ml of the unknown steel solution (digested sample), the absorbance was 0.248. calculate the concentration, in parts-per-million (ppm), of mn in the digested steel sample solution.
