The empirical formula of a compound is CH. at 200.0 degrees C,.0.193 g of this compound occupies 97.2 ml at a pressure of .740 atm. what is the molecular formula of this compound?
Until 200 yr ago, manufactured iron contained charcoal produced from freshly cut wood that was added during the smelting process. As a result of this practice, older samples of iron can be dated accurately using the carbon-14 method
The total pressure in the system is found to be 3.0 atm and the mole fraction is 0.12. Find K(pressure) Can someone explain all the steps to get to the answer?
ethanol melts at -114c and boils at 78c. its density is 0.789 gml. the enthalpy of vaporization is 38.56 kjmol and its
The linear molecule FeH2 has been observed in the gas phase. Assume that the iron atom can potentially use s, p, and d orbitals to interact with the hydrogens. If the z axis is collinear with the molecular axis
The next items refer to the result of mixing 400. ml of 0.10 M NaOH and 100.0 mL of 0.10 M Mg(NO3)2. Reaction as shown goes essentially to completion.

What mass of C4H6 in grams is consumed in the reaction below when 36.9 grams O2 (g) are also consumed?
Use the following data to plot the inflection points for the heating curve of 1 mole of solid octane at its melting point, -56.8 degrees C. The first point should be at -56.8 and the last point should be at 150 degrees celcius.
Quicklime (CaO) is produced by thermal decomposition of calcium carbonate(CaCO3). Calculate the volume of CO2 at STP produced form the decomposition of 146 g CaCO3 by the reaction: CaCO3(s) -> CaO(s) + CO2(g)
Consider a piece of gold jewelry that weighs 9.55 g and has a volume of 0.660 cm^3. The jewelry contains only gold and silver, which have densities of 19.3 {rm g}/{rm cm}^{3} and 10.5 {rm g}/{rm cm}^{3}, respectively.
