Calculate the percent yield of the reaction of 205 grams aluminum hydroxide with 751 grams hydrogen sulfate (sulfuric acid), given that 252 grams aluminum sulfate are produced
Water dissolves table salt (NaCl) because: A. NaCl is hydrophobic. B. NaCl has a polar covalent bond. C. water molecules surround the Na and Cl ions due to electric attraction.
If all the energy obtained by by burning 1.26 lb of butane (fuel value is 10.85 kcal/g) is used to heat 126.0 kg of water at an initial temp of 19.7C, what is the final temperature.
what is the rate constant for this reaction at 398 K ? I know that the answer is 1.2 s-1 but I don't know how to get it . Can anyone explain it to me please?
Based on standard reduction potentials, would you expect copper metal to oxidize under standard conditions in the presence of oxygen and hydrogen ions
