considering the given chemical equation 2H2s(g)=2H2(g)+S2(g) for the equilibrium where given Kc=9.0x10^-8 at the temperature of 700 degree Celsius the initial concentration of the three gases are.3M H2S,.3H2 and .150 S2 you just need to determine the equilibrium concentrations of all these given 3 gases?
A solution, made by dissolving 62.07 g of a nonelectrolyte in 500 g of H2O, exhibits a freezing point of -1.86 °C. Determine the molecular weight of this nonelectrolyte compound? For water Kf = 1.86 °C m-1Kb = 0.51 °C m-1
Determine how much dolomitic lime(is an anhydrous carbonate mineral composed of calcium magnesium carbonate CaMg(CO 3 ) 2 ) is required to apply to raise the pH to 7.0?
Compute the molecular formula of CH 3 COOH the percent composition of acetic acid is 39.99% C and 6.73% H. The remainder of the compound is oxygen.(The molar mass of acetic acid is 60.06 g/mol.)
volumetric flask and this solution becomes quite warm, but after it is permitted to return to room temperature, H 2 O is combined to total 500 mili litres of solution. Compute the pH of the final solution. ?
Understanding the basics of thermal chemistry and The Second Law of Thermodynamics indicates that a system
The resulting solution freezes at 26.5 oC. If Kf for the solvent is 1.74 o C/m then determine the molar mass of the nonelectrolyte compound?
How do you calculate the force of water hitting a concrete cylindrical pole. The velocity of the water is 2 ft/s, the depth of the water is 10 ft, and diameter of the pole is 3 ft. So what would be the total force exerted on the pole by the water?
