This is my second time submitting this question, please help write out equations even if it is just for the 1st sample so I can apply the values for 2 and 3.  Please help me understand the equations for this table.  How do I calculate the moles of NaOH and acetic acid?  How do I calculate the mass of acetic acid?  How do I calculate the molarity and % mass of acetic acid.  Thanks! moles of NaOH = 1.0 M x 6.2 mL x 1 L/1,000mL = 0.0062 moles NaOH - from lab manual the experimental data is in the picture with blue answers, the second part of the table I need help with.

3. Zinc reacts with hydrochloric acid to make zinc chloride and hydrogen. Zn + HCI 220g elain what will happen to the mass of the flask and its contents as the reaction proceeds.

Here is a graph of the molarity of hydrogen peroxide (H,0,) in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below. 0.30- 0.269 0.25- 0.20- M 0,15- 0.10- 0.05 - 500 1000 1500 2000 2500 3000 seconds created x10 Is H,O, being created or destroyed by the chemical O destroyed reaction? neither created nor destroyed If H,O, is being created or destroyed, what is the rate at which it is being created or destroyed 700 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If H,O, is being created or destroyed, what is the average rate at which it is being created or destroyed during the first 700 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol.
