Explain the following: a. Ethylene, C 2 H 4 , is a planar molecule, but hydrazine, N 2 H 4 , is not. b. ICI 2 is linear, but NH 2 is bent. c. Of the compounds mercury(II) cyanate, Hg(OCN) 2 , and mercury(II) fulminate, Hg(CNO) 2 , one is highly explosive, and the other is not.

Determine the moles of H+ reacting with the metal based on the following experimental data. 10.00 mL of 1.00 M HCl solution is added to a sample of Mg metal. The reaction goes to completion and all of the Mg metal is gone. 24.57 mL of 0.30 M NaOH solution is required to reach the end point when titrating the remaining HCl.

(chromated copper arsenate) for residential use. CCAtreated lumber has a light greenish color and was widely used to build decks, sand boxes, and playground structures. Draw the Lewis structure of the arsenate ion (AsO43) that yields the most favorable formal charges. Double click on an atom to type a different element symbol. Click on the button

Which of the following double displacement reactions will occur complete the equations that do Mg2, SO42 2 Na, 2 OH Ni2, CI 2 Na, 2 Br Ag, NO3Na1, 11 Ca2, Cl AI3,3 NO3 Pb 2, 2 NO3 2 Na, 2 Br

The relative length of the "tail" behind each molecule in both diagrams indicates its velocity. Use that in your answers as well as discuss what it means that they are at same V, P&T. Also, be sure to give an explanation for all parts of every question (e-g., part b needs an explanation) Questions All four balloons above are at the same volume,

Stoichiometry Prolonged exposure of some functionalities to the eluent (methanol) in this experiment may lead to undesirable reactions. In one case, Acetylsalicylic acid (Aspirin) can react with methanol to form salicylic acid and methyl acetate. If 500 mg of Acetylsalicylic acid undergoes such a side reaction (Methanolysis) to completion, draw

The reaction of ethane gas (C 2 H 6 ) with chlorine gas produces C 2 H 5 Cl as its main product (along with HCl). In addition, the reaction invariably produces a variety of other minor products, including C 2 H 4 Cl, C 2 H 3 Cl, and others. Naturally, the production of these minor products reduces the yield of the main product. Calculate the
