Use the balanced equation for the reaction to determine how many grams of H2O2 were decomposed in the reaction and how many milliliters of liquid water would be collected upon cooling (assume a density of water of 1 g/mL). Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test. Please mark the problem clearly and show your work. Enter your answers in the text box below.   grams of H2O2:    milliliters of H2O(l):

The following graph shows the progression of a reaction between molecular hydrogen (H2) and molecular (I2) to produce hydrogen iodide (HI). Referencing the graph, answer the next 7 questions.

Identify the principal intermolecular force in the following halogens: Cl2, Br2, or I2. Then, place them in order of the weakest to strongest intermolecular forces. Submit your response using the text editing tools in the box below. Intermolecular force:  [force] London dispersion  Order (weakest to strongest intermolecular forces):  [weakest] [middle] [strongest]

Aluminum has a specific heat of 0.215 cal/g °C and a density of 2.7 g/ml. If you have a 15.0-milliliter block of Al at 25.0 °C, and you add 50.0 cal of heat, what is the final temperature of the metal block?

The number of calories in 3.0 g of glucose (blood sugar) is listed as 10.0 cal. If 15.0 g of glucose is reacted in a calorimeter, such that all of the energy is released and captured in a 1,000.00-gram water bath surrounding the calorimeter, what is the expected final temperature of the water following the reaction if the initial water temperature is 21.0°C? The specific heat of water is 4.18 J/g °C or 1.00 cal/g °C. Work out the problem on a separate piece of paper and upload a photo of your response at the end of the test.
