Draw a complete lewis structure for the conjugate acid of Nitromethane (condensed formula CH3NOOH). Draw a complete lewis structure that shows all bonds, unshared electron pairs, and minimized formal charges where appropriate.
MgNH4PO4.6H2O loses H2O stepwise as it is heated. Between 40c and 60 the monohydrate is formed, and above 100 celcius the anhydrous material is formed.What are the phosphorus percentage of the monohydrate and of the anhydrate material?
Suppose you have 0.001 M solution of a dye with pka of 7.2. from the color, concentration of protonated form is found to be 0.0002 M. Assume remainder of the dye is in the deprotonated form. What is the pH of the solution?
the meta and para forms of phenylene diamine are used in the production of Kevlar and Nomex, respectively. Why is a corresponding material with similar properties not made from ortho-phynelene diamine
When considering the Ideal Gas equation of state, the molecules in the gas are assumed to have no interaction with each other at all. In real gases, however, attractive intermolecular forces exist between the molecules in the gas
Draw N-ethyl-3-methylpentanamide. Draw your structural formula with all necessary hydrogen atoms.
Calculate the total concentration of lead dissolved ([Pb]total) in a solution saturated with PbI2(s) and containing dissolved I- with a concentration of [I-] = 0.294 M. The solubility of lead is governed by the reactions shown below.
The experiment all you observed rate law is rate =k [NO]^2 [Br2]. Show this mechanism is valid by deriving the rate law expression and showing that it is equal to the experimentally observed rate law
Determine how many grams of Oxygen(O2) would be used when 10.82 Litres Nitric oxide (NO(g) is formed at the temperature of 19.82 degree Celsius and pressure of 1.092 atm?
Estimate how much heat is required to melt a single snowflake using heat capacity relationships. Assume there are 500 water molecules in a snowflake.
What is the enthalpy of this reaction? Assume that no heat is lost to the surroundings or to the coffee cup itself and that the specific heat of the solution is the same as that of pure water.
Phosphoric acid, H3PO4(aq), is a triprotic acid, meaning that one molecule of the acid has three acidic protons. Estimate the pH, and the concentrations of all species
The atomic weight of Sm is 150.36 and that of Nd is 144.24. The isotopic percentage abundance of 147Sm is 15.0 and that of 144Nd is 23.954.
