2NaHCO3 -> Na2CO3 + H2O + CO2
What is the theoretical atom economy of this reaction? Sodiumcarbonate is the desired product and water and card dioxide are theundesirable wastes.
Zinc metal is produced by the reaction of its oxide with carbon monoxide at high temperature. The equlibrium constant for the equation
The specific heat of the product is 4.06J/g deg. C and the density is 1.01g/mL. a. Calculate the heat of the reaction, q, and the enthalpy per mole.
In the determination of the density of a cylinder of aluminum, it was necessary to measure the volume of the sample. The diameter of the cylinder was 38.2 mm and the length of the cylinder was 15.5 mm. What was the volume of the aluminum cylinder ..
Arrange these ions in order of increasing ionic radius, starting from the smallest first? N^3- , O^2-, Mg ^2+ , Na+ , F- I have been told the answer is the following: 1. N^3- (Nitrogen) 2. Mg^2 (Magnesium) 3. Na+ (Sodium) 4. F- (Fluorine) 5. 0^2- ..
The entropy of a gas is larger than that of the liquid because the specific volume of gas is greater thus implying more mutual configurations are allowed for molecules in a gas than in the corresponding liquid.
Calculate the concentration of the acetate ion (mol/L) in a solution prepared by dissolving 1.00×10-2 mol of HCl(g) in 1.00 L of 9.00×10-1 M aqueous acetic acid. Equilibrium constants may be found in an appendix to your text.
Binding energy is sometimes used to hold the substrate in an optimum orientation for the chemistry to occur. E. Binding energy contributes to the decrease in deltaG°'folding for solvent molecules surrounding the enzyme.
Calculate Q,W and delta U for the conversion of 1 mole of liquid water to steam at T = 100C and P = 1 atm. The heat of vaporization of water is 9720 cal/mol.
Calculate the expected pH of a 0.100 M of ammonium chloride given that Kb for ammonia is 1.76 x 10^-5.
Explain the Coordination Chemistry and Chemical Speciation Utilized in the Analysis of Fluoride in Water Samples by Fluoride Ion-Selective Electrode.
a buffer solution is prepared by adding 15.00 g of sodium acetate nac2h3o2 and 12.50 g of acetic acid to enough water
solution were added to 12.00 mL of an aqueous 0.025 M Fe3+ solution. The total volume of the solution is 20.75 mL. What is the initial diluted Fe3+ concentration?
