The question is: The following diagram represents the collection of CO2 and H2O molecules formed by complete combustion of a hydrocarbon. What is the empirical formula of the hydrocarbon?How do I find the empirical formula of a diagram?
A sample of gas occupies a volume of 364 mL at 1.28 atm and 27 oC. Calculate the volume of the gas if its temperature is changed to 57.0 oC while its pressure is held constant.
The density of aluminum is 2.70 g/cm3. What is the volume of one mole of aluminum?
2C4H10 + 13O2 → 8CO2 + 10H2O The equation shows the combustion of butane (C4H10). How many moles of water can be produced by 12.5 moles of C4H10 with excess oxygen?
Indicate whether or not, each has a fixed shape or fixed volume. In addition, include their relative kinetic energies. Pictures can be drawn to assist in the explanation.
Suppose we doubled the volume of the solution (by adding more solvent) while keeping the quantities of the reactants constant in a SN1 reaction.
Consider a perfect gas contained in a cylinder and separated by a frictionless adiabatic piston into two sections A and B. All changes in B are isothermal. There is 2 mol of the gas in each section. Initially temperatures in both sections are 3..
