The Nitric oxide molecule, NO, readily loses one electron to form the NO^+ ion. Why is this consistent with the electronic structure of NO?
a)The Nitric oxide molecule, NO, readily loses one electron to form the NO^+ ion. Why is this consistent with the electronic structure of NO? B) predict the order of the N-O bond strengths in NO, NO^+ and NO^- and describe the magnetic properties of each. c) with what neutral homonuclear diatomic molecules are the NO+ and NO^- ions isoelectronic (same number of electrons)
a)compare the bond enthalpies of the carbon-carbon single, double and triple bonds to deduce an average pi bond contribution to the enthalpy. What fraction of single bond does the quantity represent? b) Make a similar comparison of nitrogen-nitrogen bonds. What do you observe? c) Write Lewis structures of N2H4, N2H2, and N2 and determine the hybridization around nitrogen in each case. d) Propose a reason for the large difference in your observations of parts a) and b)

Consider the arrangement of bulbs in the drawing. Each of the bulbs contains a gas at the pressure shown. What is the pressure of the system when all the stopcocks are opened, assuming that the temperature remains constants? WE can neglect the volume of the capillary tubing connecting the bulbs
Chlorine dioxide gas (Cl02) is sued as a commercial bleaching agent. It bleaches materials by oxidizing them. In the course of these reactions, the ClO2 is itself reduced. a)What is the Lewis structure for ClO2? b)Why do you think that CLo2 is reduced so steadily c) When a ClO2 molecule gains an electron, the chlorite ion, CLo2-fpr,s. Draw the Lewis structure for CLO2-. d) Predict the O-Cl-O bond angle in the ClO2- ion. e) One method of preparing ClO2 is by the reaction of chlorine and sodium chlorite:
Cl2(g)+2NaClO2(s)-->2Clo2(g) + 2NaCl(s)
If you allow 10.0g of NaClO2 to react with 2.00L of chlorine gas at a pressure of 1.50 atm at 21 degrees celcius, how many grams of ClO2 can be prepared?

Hydrogen bonding between polyamide chains plays an important role in determining the properties of a nylon such as nylon 6,6 . Draw the structural formulas for two adjacent chains of nylon 6,6 and show where hydrogen-bonding interactions could occur between them.
Silicon has a face-centered cubic crystal structure with unit cell edge length of 5.43 and four atoms per unit cell a)How many silicon atoms are there in 1 cm^3 of material? b) Suppose you dope that 1-cm^3 sample of silicon with 1ppm of phosphorus that will increase the conductivity by a factor of a million. How many milligrams of phosporus are required?
Canned heat product is used to warm and consists of homogenous mixture of ethanol C2H5OH and paraffin that has an average formula of C24H50. What mass of C2H5OH should be added to 620kg of the paraffin in formulating the mixture if the vapour pressure of ethanol at 35 degrees celcius over the mixture is to be 8 torr? The vapour pressure of pure ethanol at 35 degrees celcius is 100 torr.
