A heater burns normal Butane (n-C4H10) using 40% excess air. combustion is complete . the flue gas leaves the stock at a pressure of 100 kpa and a temperature of 260 c
a) calculate the complete flue gas analysis.?
b) what b is the molar concentration of CO2 in the stock?
the heat calculated after a calimetry experiment is equal to the enthalpy change for reaction. Use the thermochemical data to calculate the enthalpy chanfe for the reaction of NaOH and CH3COOH.
What are the concentrations of HSO4-, SO42-, and H+ in a 0.14 M KHSO4 solution? (Hint: H2SO4 is a strong acid; Ka for HSO4- = 1.3 10-2.)
What is the partial pressure of each gas and total pressure of the mixture of gaases, in atmospheres, in the container?
An experiment requires 42.0 g of ethylene glycol, a liquid whose density is 1.114 g/mL. Rather than weigh the sample on a balance, a chemist chooses to dispense the liquid using a graduated cylinder.
The activation energy of a reaction is the difference between the energy states of reactants and the products
A sample of gas occupies 250. mL at 37 degrees celsius and 730. torr; what volume would the gas occupy at standard conditions?
what is the rate law? b) calculate the value of the rate constant c)calculate the initial rate for an experiment when both I- and OCl- are initially present at 0.15 mol/L
Would your calculation of the atomic mass of the metal be too high or too low if your hot metal sample cooled off, unbeknownst to you, while being transferred to the calorimeter?
What does a yellow flame in the Bunsen burner indicate? How can this be corrected? Why use a funnel to transfer large volume of liquid from one container to another?
Calculate the theoretical yield of C2H5Cl when 123g of C2H6 reacts with 213g of Cl2 , assuming that C2H6 and Cl2 react only to form C2H5Cl and HCl.
