Chem help again sorry lol 1)Consider mixing HNO3 and NaNO3. This is NOT a bluffer(take the l out, basil banned it lol) because 1. HNO3 is not a weak acid. 2. NaNO3 is basic. 3. Na reacts with water to form OH-. 4. NaNO3 is not soluble. 5. NO-3 reacts with water to form NO2(g). 2)What is [OH-] in a 0.0045 M HCl solution? 1. 4.4 x10^12 M 2. 1.0x10^12 M 3. 0.00225 M 4. 2.2x10^12 M 5. 0.0045 M 3)Identify the acid in the reaction O^2-(aq) + H2O(l) -> 2 OH-(aq) 1. O 2-(aq) 2. H2O(l)(aq) 3. OH- 4. None of these 4)For the neutralization reaction involving HNO3 and Ca(OH)2, how many liters of 1.55 M HNO3 are needed to react with 45.8 mL of a 4.66 M Ca(OH)2 solution? 1. 0.330 L 2. 0.137 L 3. 0.275 L 4. 0.662 L 5. 0.0343 L 6. 1.32 L 5) What volume
