A small crystal of I2 is often used to clean the surface of themagnesium metal in the syntheses of Grignard reagents. Write abalanced chemical equation for the reaction of magnesium and molecular iodine.
The reversible chemical reaction A+B C+D with an equilibrium constant of K 7.1.Initially, only A and B are present, each at 2.00 . What is the final concentration of once equilibrium is reached?
Considering which elements are being oxidized and reduced, determine how many moles of electrons are transferred between the elements being oxidized and reduced
Carbon-14 dating can be used to estimate the age of formerly living materials because the uptake of carbon-14 from carbon dioxide in the atmosphere stops once the organism dies
A solution of Chloroform (CHCl3) and Acetone ((CH3)2CO) exhibits a negative deviation from Roult's law. The result implies that
what is the constant k for this reaction. what is the rate of the reaction if the initial concentrations of [A] = .400M, [B]= .0500M and [C]= .075M
Draw a six-carbon-chain portion from syndiotactic polypropylene, in which the CH3 groups lie on alternating sides of the plane of the computer screen
Using curved arrows to show the flow of electrons and being careful to balance mass and charge for each step, provide a mechanism for the reaction below that show how both products are formed
system and show how the pH will change upon addition of 10.0 mL each of ) 0.10 M of HCl or NaOH. Use any combination of weak acid and its salt OR weak base or its salt.
In 1774, Joseph Priestley discovered that mercury(II) oxide decomposes on heating to elemental mercury and a gas, later called oxygen. If 56.0 g of mercury(II) oxide is heated and 26.0 % of it decomposes,
a 6.0-g sample of nih2o6cl2 is dissolved in aqueous solution. if an excess of ethylenediamine en is added to the
How much heat (in kj) is needed to convert 776g of ice at -10 degrees celsius to steam at 126 degrees celsius. (the specific heat of ice water and steam are 2.03 J/g . C, 4.184 J/g . C, 1.99 J/g . C, respectivley. The Heat of Fusion of water is 6...
For each of the following give the sublevel designation (name of orbital), the allowable ml values, and the number of orbitals- a. n = 5, l = 3 c. n = 2, l = 0 b. n = 3, l = 1 d. n = 6, l = 2
