1. Draw the structural formula of 3-hexene (C6H12). What class of organic molecule is 3-hexene?
Describe an isomer. Draw an isomer of 3-hexene.
2. Draw the structural formulas of the four-carbon hydrocarbons butane, 1-butene, and 1-butyne. Classify each molecule, and explain the differences between them.
PH of solution during titration process, Q1: What is the pH of a 0.35 M solution of a weak acid HA with Ka = 1.41×10^-8?
Titrated with 0.10 M HBr. Determine the pH of the solution after the addition of 400.0 mL HBr.
Decide if the compound/ion listed can satisfy the octet rule (duet rule for H), if so choose Satisfies Octet Rule from the drop down menu. If the compound/ion cannot satisfy the octet rule for one of the atoms in the formula, choose one of the fol..
a equimolar mixture of h2 and d2 effuses through an orifice at a certain temperature. calculate the composition in mole
The resulting mixture exerts a pressure of 731 mmHg at 83°C. (a) What is the partial pressure of each gas in the container (in mmHg)? (b) What is the mass of the original sample (in g)
The flask shown here contains 0.450 g of acid as well as a few drops of phenolphthalein indicator dissolved in water. The buret contains 0.200 M NaOH. Explain what volume of base is needed to reach the end point of the titration. Presuming the aci..
A mixture of cyclopropane gas and oxygen in a 1:4 mole ratio is used as an anaesthetic. What masses of each of these gases is present in a 2.00 L bulb at 23.5 degrees C if the total pressure is 1.00 bar?
Acetylenic fatty acids are found in many tropical plants. Compound H, C18H26O2, is one such compound; it absorbs 5 equivalents of H2 when treated with H2 over a Pd/C catalyst. Ozonolysis of compound H produces the following products
A mixture of 0.162 moles of C is reacted with 0.117 moles of O2 in a seated, 10.0 L vessel at 500 K, producing a mixture of CO and CO2. The total pressure is 0.640 atm. What is the partial pressure of CO
