For those of you who came to the review in class today‚ The stoichiometry question from class. I read the answer to the wrong decimal place. --What is the total mass of oxygen in 0.26mol of Cu2O? Find the percent of oxygen in Cu2O first. The molar mass of Cu2O is 143‚ the mass of just the oxygen in it is 16. % Composition of oxygen would be 16/143 times 100 is 11.19%‚ To determine the mass of Cu2O in 0.26 mol‚ multiply by the molar mass of Cu2O. This gives

Title: Stoichiometry Reaction Objectives: 1. To decompose sodium hydrogen carbonate (sodium bicarbonate) by heating. 2. To accurately measure the degree of completion of the reaction by analysing the solid sodium carbonate product. 3. To calculate amount of product with given amount of reactant. 4. To determine amount of heat release in the reaction. Results: Part 1: Thermal Decomposition of NaHCO3 Materials Mass (g) Clean and dry test tube 15.1632 Clean test tube + NaHCO3 17.1647

Na2CO3(s)+CO2(g)+H2O(g). The was the only equation that matched up exactly with my data in terms of percentage. To start off with‚ when I balanced out the equation‚ I got 2 NaHCO3→ 1 Na2CO3(s)+ 1 CO2(g)+ 1 H2O(g). Therefore when I set up my stoichiometry problem I got 3.2 grams NaHCO3 over 1 x 1 mol NaHCO3 over 84.007g NaHCO3 x 1mol Na2CO3 over 2 mol NaHCO3 x 105.987g Na2CO3 x 1 mol Na2CO3. Hence‚ I multiplied 3.2 x 1 x 1 x 105.987 and got 339.1584. Afterwards‚ I divided 339.1584 by 84.007 and

and Simple 1D Collisions PhET Lab Introduction: When objects move‚ they have momentum. Momentum‚ p‚ is simply the product of an object’s mass (kg) and its velocity (m/s). The unit for momentum‚ p‚ is kgm/s. During a collision‚ an object’s momentum can be transferred to impulse‚ which is the product of force (N) and time (s) over which the force acts. This allows us to write the momentum-impulse theorem: Procedure: Play with the Sims Physics Motion Collision Lab Work with 1D collisions
