QUESTION 25When 2.5 moles of calcium carbonate is added to 4.8 moles ofhydrochloric acid, calcium chloride, carbon dioxide, and water areproduced: CaCO3(s) + 2HCl(aq) → CaCl₂(aq) +H₂O(l) + CO₂(g)Which equation below represents the calculation for the number ofgrams of calcium chloride that are produced if the reaction proceedswith a 65% yield?A. 2.5 moles CaCl₂ * 110.98 grams/mol * 0.65B. 2.4 moles CaCl₂ * 110.98 grams/mol * 0.65C. 2.5 moles CaCl₂ * 110.98 grams/mol / 0.65D. 2.4 moles CaCl₂ * 110.98 grams/mol / 0.65OABCOD Octane (C8H₁8) is a straight chain of carbon atoms with no dipolemoment and a boiling point of 125°C. Water has a dipole moment,can hydrogen bond and has a boiling point of 100°C. The differencebetween these two boiling points can best be rationalized by:A. Intermolecular forces between molecules with dipole momentsare greater than between molecules with no dipole momentB. Hydrogen bonding is a strong intermolecular forceC. London dispersion forces are weak but there are many LDFs inoctane so the net IMF in C8H₁8 is greater than the net IMF in H₂OD. London dispersion forces are strong and so the boiling point ofoctane is greater than the boiling point of waterO AOBO COD
