Lead can be extracted from a mineral call galena(PbS). An ore contains 3.4% galena by mass. How many kg of ore is needed if you want to extract 100. grams of lead?
How much heat must be extracted from 750 mL of white wine to cool it from 25 °C to 13 °C, if the wine is 9.6% ethanol by weight? Assume the wine can be treated as an aqueous solution of ethanol, with no other components. The molar heat capacity of water is 75.4 J/mol K and of ethanol is 112.1 J/mol K. Also: Show that this corresponds to a wine that is 12% alcohol by volume, or ABV. Clearly state...

When your cells need energy, they extract it from adenosine triphosphate(ATP). But how did the energy get into the ATP? A) Energy was extracted from the food I ate by photosynthesis and store into ATP. B) ATP is a carbohydrate, which makes it a good source of energy. C) Energy was extracted from the food I ate by cellular respiration and stored into ATP. Give me an answer and a brief explanation that is 1-2 sentences in complete sentences. Avoid...
