A gaseous fuel mixture contains 23.0% methane CH4, 44.0% ethane C2H6 and the rest propane C3H8 by volume. When the fuel mixture contained in a 1.53L tank, stored at 748 mmHg and 298 K, undergoes complete combustion, how much heat is emitted?
what is the lewis structure and molecular geometry of pernitrate and carbonate ion?
In high spin complexes, the crystal field splitting energy is small and in low spin complexes, electrons are concentrated in the lower energy orbitals.
Suggest a chemical test that would allow you to distinguish between tert-butyl alcohol and 1 butanol, both of which give a positive ceric nitrate test?
What is the final concentration of Na+ after adding 230 ml of water to a stock solution of 2.5M 420.0 ml Trisodium phosphate?
At a Concentration of 1M, the weak acid HN0 is 2% ionized and the pH of the solution is 1.7 . What happens when KNO2(s) is dissolved into the solution: The extent of HNO2 ionization = Increases or decreases? The concentration of H+ = Increases or ..
What is the power output of the turbine? H1= 1322.6 Btu/lbm v1=3.058 (ft)^3/lbm H2= 1148.6 Btu/lbm v2=78.14 (ft)^3/lbm
As a reaction progresses backwards toward equilibrium K is the highest value Q attains. e) A reaction with no products present has an infinite Q value.
Sulfuric acid (H2SO4) is prepared commercially from elemental sulfur using the contact process. In a typical sequence of reactions, the sulfur is first burned
A piece of dry ice (solid carbon dioxide) with a mass of 31.5 g is allowed to sublime (convert from solid to gas) into a large balloon.
Determine the maximum amount of P4S10(444.545 g/mol) that can be produced from 18.27 grams of Phosphorous (123.895 g/mol) and 9.42 g of sulphur (256.52 g/mol)
From the Mn concentrations (3.56ppm and 3.71ppm) and uncertainty
