How to understand stoichiometry easily?

Here is a graph of the molarity of thionyl chloride (SOC1₂) in a reaction vessel during a certain chemical reaction. Use this graph to answer the questions in the table below. M 0.030- 0.025- 0.0219 0.020- 0.0176 0.015. 0.009703 0.005- 0 1011 seconds Is SOCI, being created or destroyed by the chemical reaction? If SOCI, is being created or destroyed, what is the rate at which it is being created or destroyed 11 seconds after the reaction starts? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. If SOCI, is being created or destroyed, what is the average rate at which it is being created or destroyed. during the first 11 seconds of the reaction? Round your answer to 2 significant digits. Also be sure your answer has the correct unit symbol. 24.513 created O destroyed 30 neither created nor destroyed 0 X 0 ☐ x10 믐 X ロ・ロ

Consider the following chemical reaction HCl (aq)  + HgNO3 (aq) à Hg2Cl2 (s) + HNO3 (aq) If 20.0 grams of HCl is mixed with 30.0 grams of HgNO3     Determine the excess reactant   The amount of the solid precipitate that was recovered equals to .................. grams , if the percentage yield from this reaction was determined to be 78.4%. Write the net ionic equation for the chemical reaction   Determine the type of this chemical reaction

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.
