4. One day while working the in lab, I decide to warm a cup of water to make some tea. I place the cup of water (250.0 mL) on top of a ring clamp and light a Bunsen burner (which burns methane gas). I want to heat the water from 15.0°C to 40.0°C. Determine the heat of combustion for methane. CH4(g) +202(g) → CO2(g) + 2H₂O(v) a. Given: → CH4(8) C) + 2H2(g) C(s) + O2(g) → CO₂ H₂(g) + 1/2O2(g) → H₂O() 2(g) AH = -74.87 kJ/mol AH-393.5kJ/mol AH = -285.8kJ/mol

Instructions for this problem say, "Solve each problem and report your answer to correct significant figure and units. Remember that units multiply, divide, add, subtract, and simplify just like variables." (23.0 lb/gal)(2 ft) = Do I need to convert any of the units? Or can I simply multiply, leaving me with a unit of "ft lb/gal"? None of the other problems in this section have space or required a lot of work to be shown. Image of my attempt attached.
How many hours are in exactly 18 days? The answer has how many stick figures?
(CONTINUED ON NEXT PAGE) 4. Let's say that the full volume of your flask is 325 ml. You heat the flask of air in a hot water bath at 89.0°C according to your thermometer. You then inverti into the cold water bath at 5.0°C Water enters the flask as the volume of the gas shrinks. a) Theoretically, what should the volume of the gas be after it sits in the cold water bath? b) You find that during your experiment that 65.0 mL of water has entered the flask. What is the experimental volume of the gas? c) What is your percent error for this measurement?
I have a question. for the first question, wouldn't I divide 2.202 by 6.626 and divide by 100?? & how would I work the second questions?
This is not graded! It is strictly for practice. Do questions 1-5.
7. What is the mass in grams of a 34 oz salt? Local gravity is 9.65 m/s²? Include also a diagram or figure.
