Hello! Could you help me go trough the steps of this question? You have a solution of formic acid. The solution has been prepared by dissolving 6.90 g of pure formic acid in water to the total volume, V = 1.00 L. a) Calculate the solution pH. (I want to put this in a table, but what will happen with the initial step of the RICE table? It did not start on M, i got it in g....) b) You...

I. What is the heat capacity of 185g of liquid water? How many Kilojoules are needed to raise the temperature of 10 kg of liquid water from 24.6°C to 46.2°C and 38.5 mol of water from 38.1°C to 79.4°C? Ans: 774.04J/gC, 903.74Kj, 119.75KJ 2. A 2.200 g sample of quinone, C&402. is burned in a bomb Calorimeter whose total heat capacity is 7.854 kJ C. The temperature of calorimeter increases from 23.44°C to 30.57C. What...

2. 3. 4. Repeat steps 0.a.-f. for TITRA2 and TITRA3. Write the balanced chemical equation for the reaction between your unknown acid and sodium hydroxide. The generalized chemical formula of your acid (HxA) is found on the unknown sample bottle. “X” denotes the number of hydrogen's that react with the hydroxide on the sodium hydroxide. Go back to the TITRA1 D2 EXPANDED graph and determine the equivalence point volume of sodium hydroxide used to titrate...

Pre-Lab Questions: 1. What is the definition of an 'equivalence point' in an acid/base titration? (1 point) 2. In part one of the experiment, you will prepare the acid solutions being titrated from a stock solution. Describe how you will accurately prepare 10.00 mL of 0.100 M HCl solution using a 1.00 M HCI stock solution. In your response to this question, be very specific about the quantities of stock solution and...
