For the decomposition of CaCO3 (s) into CaO (s) and CO2 (g) at 1 atm, estimate the minimum temperature at which you would conduct the reaction.
The concrntration of the alkane C20H42 (FM 282.55) in particular sample of rainwater is 0.2 ppb. Assume that the density of rainwater is close to 1.00 g/mL
Calculate the molar mass that would be obtained from the actual experimental data under the following conditions. The unknown is methyl propyl ether (CH3OC3H7)
Ascorbic acid (Vitamin C, H2C6H6O6) is a diprotic acid. In a laboratory exercise, a vitamin C tablet was analyzed by titration using 0.125 M NaOH(aq). On the average, it required 29.5 mL of the base to neutralize the acid in the one tablet. How ma..
What is the maximum number of electrons in an atom that can have the following set of quantum numbers?
Calculate all the preceeding concentrations and the weight of biomass, {CH2O}, produced. Assume no input of atmospheric CO2.
Earth's oceans have an average depth of 38000m, a total area of 3.63*10^8km^2, and an average concentration of dissolved gold of 5.8*10^-9g/L. a) how many grams of gold are in the oceans?
What is the wavelength, in nanometers, of the light emitted when the electron in a hydrogen atom drops from the energy level n_i = 12 to n_f = 5
Write an equation, clearly showing the stereochemistry of the starting material and the product, for the reaction of (S)-1-bromo-2-methylbutane with sodium iodide in acetone.
Gaseous indium dihydride is formed from the elements at elevated temperature: In(g)+H2(g) (reactions goes both ways=double arrow) to InH2(g) with Kp=1.48 at 973 K
A sample of 0.0020 mole of HCl is dissolved in water to make a 2000-mL solution. Calculate the molarity of the HCl solution, the [H3O+], and the pH. For a strong acid such as HCI, the [H3O+] is the same as the molarity of the HCl solution.
