When the 1-bromobutane is first formed it often has a yellow or brown color, but pure 1-bromobutane is colorless. explain why in your own word please
How much corn syrup and how much water would you need to combine to create 500 ml of 10% corn syrup solution? Explain
chlorobutenedioic acids dehydrochlorinate to give acetylene dicarboxylic acid. The Z reacts about 50 times faster
during one of the processes at the plant. The two liquids are blended until a specific gravity of 1.445. Determine the mole percentage of the two components in the blend.
Calculate the energy and the wavelength, in nanometers, of light emitted when an electron in an excited hydrogen atom falls from the n=3 level to the n = 1 level.
Calculate the change of entropy for the water, ΔSwater , and for the surroundings, ΔSsur , when 1.00 mole of water freezes at 0°C and the surroundings are at (a) 0°C, (b) -2°C. Explain the physical origin of the difference.
a mixture with 75% R and 25% S has an optical rotation of -30. what is the optical rotation of pure R?
Consider the two gases, NO and CO2. Ten grams of each are placed in balloons at STP. Which of the following is an accurate comparison?:
At high temperature, ammonia reduces copper(II) oxide to the free metal: Step 1: 2NH3(g) + 6CuO(s) => N2(g) + 3Cu2O(s) + 3H2O(g) Step 2: 2NH3(g) + 3Cu2O(s) => N2(g) + 6Cu(s) + 3H2O(g)
how many g of A will be transferred to the new ether layer? (K remains the same, even though the number of g of A being partitioned is smaller. How many total g of A have been extracted into the two ether fractions?
Calculate the expected change in temperature for 1.7 g of NH NO dissolved in 50.0 2 cal mL of H O. Assume that the calorimeter absorbs no heat. (ie. C =0)(Remember to use dimensional analysis
Integrate the expression b = 1/V (derivative of V / derivative of T) at constant pressure, assuming that b is independent of temperature. By doing so, obtain an expression for V as a function of T and b at constant P. b means beta
