PLEASE HELP!! WILL GIVE 5 STARS, A THANKS AND BRAINLIEST ~you will get reported if you put any links, or no answer. please do not report the question I did not do anything wrong~
Read the article excerpt below then answer the question.
How does burning carbon-containing fuels contribute to Earth’s climate change problem?
The chemical reaction that happens when ethanol and oxygen mix produces two substances: carbon dioxide and water in the gas phase. Since both of these are invisible, colorless gases, it seems like nothing is left of the liquid that was in your gas tank. However, the atoms of the reactants haven’t disappeared at all—they’ve only rearranged to form the products. The carbon dioxide and water produced by this chemical reaction enter the atmosphere whenever we burn ethanol or other carbon-containing fuels. In the recent past, humans have increased the amount of carbon dioxide in Earth’s atmosphere by burning such fuels, resulting in widespread changes to Earth’s climate. In response to these effects, scientists are working to find fuels that can release energy without producing carbon dioxide.

Astudent is given a sample of a blue copper sulfate hydrate. he weighs the sample in a dry covered porcelain crucible and got a mass of 23.875 g for the crucible, lid, and sample. the mass of the empty crucible and lid was found earlier to be 22.652 g. he then heats the crucible to expel the water of hydration, keeping the crucible at red heat for 10 minutes with the lid slightly ajar. on colling, he finds the mass of crucible, lid, and contents to be 23.403 g. the sample was changed in the process to very light clue anhydrous cuso4. if there are again 100.0 g of hydrate, how many grams of cuso4 are in it? how many moles of cuso4? (hint: molar mass of cuso4 = 159.6 g / mole. what per cent of the hydrate is cuso4? you may convert the mass of cuso4 to moles.)
