Desribing molecular forces of C5H6O
CH2=CH-CH=CH-CH=O
THREE double bonds.
Describe the bond and angle terms of this structure.
not confident about what it is - it looks like a ring structure and I have been unable to find it using familiar web searches.
assuming that the bond terms are C-C, C-H, C=O and C=C
yet to figure out the angle terms (described in the text as a spring like force to preserve bond angles).
115 mL of H_2O is initially at room temperature 22 0C. A chilled steel rod at 2 0C is placed in the water. If the final temperature of the system is 21.1 0C, what is the mass of the steel bar.
What is the molecular formula of a compound with the empirical formula NO¿ and a molar mass of 138.02 grams per mole?
Determine the average atomic mass of boron is the natural abundance of 10B weighing exactly 10.0129 amu is 80.1% and the natural abundance of 11B weighing exactly 11.0093 amu is 19.9%.
At 250C, the equilibrium constant Kp for the reaction PCl5(g) PCl3(g) + Cl2(g) is 1.80. Sufficient PCl5 is put into a reaction vessel to give an initial pressure of 2.74 atm at 250C. Calculate the pressure of PCl5 after the system has reached equi..
A weather balloon at Earth's surface has a volume of 4 L at 294 K and 746 mm Hg. If the balloon is released and the volume reaches 4.19 L at 715 mm Hg.
Describe how this observation is consistent with the law of conservation of charge.
Calculate the amount of heat [kcal] released when 50.0 g of steam at 100 °C hits the skin, condenses, and cools to a body temperature of 37 °C.
If one mole of ATP yields 7 kcal of energy, how much energy would be available from the anaerobic catabolism of 270 g of glucose (C6H12O6)? Show your work.
Stellar nuclear fusion begins with 1H and ends with 56Fe. Younger stars fuse hydrogen to form 4He, while older, more massive stars fuse helium to form heavier elements.
Questions on H-NMR spectrum of isopentyl acetate - What would the effect on yield be of allowing the crushed Dry Ice to be exposed to the atmosphere for long periods of time before being used?
In the combustion reaction of 149 g of propane with excess oxygen, what volume of carbon dioxide if produced at STP?
Calculate the concentrations of all species at equilibrium for each of the given original mixtures. 1.2 mol of NOCl and 1.2 mol of NO in a 1.0-L flask? K = 1.6*10^-5 mol/L
