r(lI) oxide reacts with hydrochloric acid to produce copper(lI) chloride and water. How many 6 gram ns of copper(lII) oxide are required for complete reaction with 25.0 mL. of 0.103 M hydrochloric acid? The molar mass of copper(l) oxide is 79.545 gmol. (Hint: start by writing the balanced equation for the reaction.) 7. A sample contains an unknown amount of maleic acid, HC+H If 0.6936 g of the sample requires 44.86 mL of 0.1000 M NaOH to neutralize the HC4H204 completely, what is the percentage of H C4H O in the sample? The molar mass of H2C4H204 is 116.07 g/mol. The balanced equation for the reaction is: H2CJH2O2 + 2 NaOH â 2 H2O + Na2CH,04 lutions can be standardized
