3. In lesson 4, you added the ionic compound potassium chloride (KCI) to water and observed a temperature change. You used 10 molecules of KCI and varied the number of water molecules. The data table below shows the resulting temperature changes if you dissolved 10 molecules of KCI in 10, 71, and 100 molecules of water. What kind of relationship does the number of water molecules have with the magnitude of the temperature change? * Number of Water Initial Molecules Magnitude of Temperature (K) Temperature (K) Temperature Change (K) Number of Final KCI Molecules 10 10 300 292.48 K 7.52 10 71 300 294.91 5.09 10 100 300 296.36 3.64 What kind of relationship does the number of water molecules have with the magnitude of the temperature change? A direct relationship An inverse relationship The data shows no relationship
Aqueous hydrobromic acid HBr reacts with solid sodium hydroxide NaOH to produce aqueous sodium bromide NaBr and liquid water H2O. If 10.0g of water is produced from the reaction of 58.3g of hydrobromic acid and 50.1g of sodium hydroxide, calculate the percent yield of water. Be sure your answer has the correct number of significant digits in it. I keep getting this problem wrong because of the sig. digits, dont round till the end because if it is off by 0.1, it will be incorrect.
John and Eli do a reaction with the goal to prove the law os conservation of mass. In the reaction, they place 50.00 g of acetic acid (CH3COOH) in a clean, dry ziploc bag and then add 5.00 g of baking soda (NaHCO3). The products of the reaction include sodium acetate, carbon dioxide, and water. In trial 1, Eli immediately seals the bag upon addition of the baking soda and waits until the bubbling comes to a halt. John weighs the closed bag with all contents and records mass in the table. For trial 2, John and Eli repeat the procedure but forgot to seal the bag. Their results are shown in the table below. 1. Calculate the theoretical mass of the open bag. 2. Are atoms/mass conserved in each of the reactions? 3. Provide mathematical evidence to explain your reasoning that atoms/mass are/are not conserved.
