1a) What is w when a gas is compressed from 38.3 L to 28.8 L using a constant external pressure of 745 mmHg?
1b) What is w when 2.47 kg of H2O(l), initially at 25.0oC, is converted into water vapour at 137oC against a constant external pressure of 1.00 atm? Assume that the vapour behaves ideally and that the density of liquid water is 1.00 g/mL.
Calculate the concentration of the acetate ion (mol/L) in a solution prepared by dissolving 1.00×10-2 mol of HCl(g) in 1.00 L of 9.00×10-1 M aqueous acetic acid. Equilibrium constants may be found in an appendix to your text.
Some 2-methyl-2-butene may be produced in the reaction as a by-product. Give a mechanism for its production. (The experiment was to react t-pentyl alcohol with HCl.)
Determine the temperature change is caused by heat energy and using a beaker that contains 100 mL of H 2 O thermally insulated from its surroundings, one mol of solid CaCl 2 is mixed and solution is stirred
How much energy must be supplied to break a single 6Li nucleus into separated protons and neutrons? (masses: 6Li, 6.01347; 1H, 1.00728; 1n, 1.00867 amu)
A solution is prepared by mixing 0.0300 mol CH2Cl2 and 0.0500 mol of CH2Br2 at 25°C. Assuming the solution is ideal, calculate the composition of the vapor
to scale-forming water to convert calcium carbonate to calcium bicarbonate. write the chemical equation for this reaction.
Explain the relationship between the electron configuration and the corresponding principal and angular momentum quantum numbers for each of your elements.
If 3.50ml of vinegar needs 42.0ml of 0.130M NaOH to reach the equivalence point in a titration, how many grams of acetic acid are in a 1.20qt sample of this vinegar?
Draw the best Lewis structure, and resonance contributors of equal energy (if any), for the molecule H2SO3 1- How many valence electrons are in your Lewis drawing
DNA double helix has the sequence GATCGATTAC, what is the sequence of the other DNA strand?
Choose the answer that shows a correctly balanced equation.
The recovered CuSO4•5H2O was then heated for 20 minutes at 120°C. The mass of the new hydrate was 2.17g. (The molar mass of H2O = 18.015 g/mol, and the molar mass of CuSO4= 159.61g/mol) Calculate the mass of CuSO4 in the new hydrate (CuSO4•XH2O).
