Why was acetyl chloride /ethanol used as source of hydrocholic acid instead of aqueous hydrocholic acid
In the following conditions calculate the moles of hydrogen and the pressure in each flask where the volume is negligible. Each flask is originally 275K with .455 mols of hydrogen gas and .7atm of pressure. Then one flask is heated to 500K while t..
The valence shell electron pair repulsion (VSEPR) theory states that molecules assume a shape that minimizes the repulsion between electron pairs and bonded atoms in the valence shell of the central atom.
The excess HCl in the solution required 94.9 mL of 0.128 M NaOH for complete neutralization in a titration. What was the molecular formula of the white substance
Given the values of ΔH ° rxn , ΔS ° rxn , and T below, determine ΔS univ. ΔH ° rxn = 80kJ , ΔS rxn = 143J/K , T= 299K Express your answer using two significant figures.
Calculate the frequency of the light emitted when an electron in a hydrogen atom makes each of the following transitions.
If a solution is made of naphthalene in heptane and has a vapor pressure of 82 torr, what is the mole fraction of naphthalene? Assume ideal solution behavior.
Hydrogen gas (H2) and oxygen gas (O2) are the products when an aqueous acidic solution is electrolyzed; each mol of water gives one mol of H2 and half a mol of O2.
I am trying to understand the effects of leachate from landfills and its effects on groundwater, and since I am in environmental health- its effects on the human health.
Hydrogen peroxide decomposes to water and oxygen, and the activation energy for this process is 42 kJ/mol. The hydrogen peroxide formed in the biological process is harmful to tissue
If the gas is an ideal gas, what pressure would develop in the can if it were heated to 475oC?
Calculating effective charges on I and Br, The iodine monobromide molecule, IBr, has a bond length of 2.49 Angstroms and a dipole moment of 1.21 D.
A solution was made by taking 1.250g of KMnO4 and dissolving it in enough water to make 1.000 liter of solution. This solution was used to titrate H2C2O4·2H2O, a very pure substance. In acidic media, the reaction is.
