Solid silicon and solid magnesium chloride form when silicon trichloride gas reacts with magnesium metal. Write a word equation and an unbalanced formula equation.
for each of the following changes at equilibrium, indicate whether the equilibrium shifts toward products or reactants or does not shift: a)increasing the temperature. b)adding C(s). c)removing CO(g) as it forms. d)adding H2O(g). decreasing the vo..
An aqueous CaCl2 solution has a vapor pressure of 82.1 mmhg at 50 C . The vapor pressure of pure water at this temperature is 92.6 mmhg What is the concentration of in mass percent?
What is the equilibrium partial pressure of NO in the air at 1000K if the partial pressure of nitrogen is 0.80bar, the partial pressure of oxygen is 0.20 bar and delta G for the following reaction is 77.772kj/mole. 1/2N2(g) + 1/2 O2(g)----NO (g)
we determined that the sample contained 5.34mol of oxygen. If all of this oxygen were converted to a gas at 24 degrees celcius and 770mmHg of pressure, what volume would it occupy?
The purpose of this experiment is to find out which fabric out of polyester, polypropylene, cotton and wool is the most suitable to make a sling back chair.
Find the partial pressure of each produce and the total pressure in the flask at the end of the reaction.
Is a first order rate constant of 3.14x10^-4 1/s at room temperature, if you currently have a 2.5 M N2O5 how long will it take for 65% of N2O react?
The gas is heated to 520.0 K at a constant volume corresponding to the initial volume c) The gas undergoes a reversible isothermal expansion at 290.0 K until the pressure is half of its initial value
A sample containing both enantiomers is found to have an observed rotation of +0.87 degrees in a one dm tube at a concentration of 0.025 g/mL. What is the optical purity of the sample? What is the % of the dominant enantiomer in this sample?
The % ionization of a weak acid always declines in a solution that contains the salt of the anion relative to a solution of the acid alone. For example the % dissociation of the acetic acid is less in a solution that contains sodium acetate than i..
determine the binding energy of an F-19 nucleus. the F-19 nucleus has a mass of 18.99849325 amu. a proton has a mass of 1.00728 amu and neutron has a mass of
Use the molar bond enthalpy data in the table to estimate the value of change in H rxn for the equation: CCl4(g) + 2F2(g) yields CF4(g)+ 2Cl2(g). Average Molar bond enthalpies
