A student has two compounds in two seperate bottles but with no labels on either one. One is an unbranched alkane, C8H18; the other is 1-hexane, and unbranched alkene, C6H12. What should you see in the following tests:

Octane 1-Hexane

A. Water Solubility

B. Ligroin Solubility

C. Combustion

D. Density vs water

E. Bromine Test

F. Permanganate Test

Expert Solution

Qualitative tests for alkane (octane) and alkene (1-hexene)

For C8H18 (Octane)

1. water solubility : Insoluble

2. Ligroin solubility : Soluble

3. Combustion : burn with clean flame, complete combustion to CO2 and H2O

4. density vs water : Less denser than water

5. Bromine test : -ve test, no color change +ve test, decolorizes bromine

6. permanganate test : -ve test, no color change . +ve test

--

For C6H12 (1-Hexene)

1. water solubility : Insoluble

2. Ligroin solubility : Soluble

3. Combustion : burn with a sooty flame, incomplete combustion to CO and H2O

4. density vs water : Less denser than water

5. Bromine test : +ve test, decolorizes bromine

6. permanganate test : +ve test, purple to light pink

A student has two compounds in two separate bottles but with no labels on either one. One is an unbranched alkane, octane (C8H18); the other is 1-hexene (C6H12), an unbranched alkene. Based on your observations in this experiment, tell what you should observe via the following tests: Octane 1-Hexene A. Water solubility B. Ligroin solubility C. Density versus water D. Bromine test E. Permanganate test

You find two bottles of white solid on a shelf in the stock room without labels. You then find two labels CaCl2 (s) and KCl (s0 lyring right beside. You want to determine which is which. The solids can be differentiated by dissolving each solid in water and measuring the change in temperature. delta H(f) CaCl2 (s) = -796 kJ/mol delta H(f) KCl (s) = -437 kJ/mol You dissolve 0.100 moles of unknown A in enough water to make a...

In Village A, one farmer, i.e., one unit of labor, can produce either 10 bottles of wine (W) or 2 bottles of olive oil (O). In Village B, one farmer can produce either 5 bottles of wine (W) or 15 bottles of olive oil (O). For now, the two villages are in a state of “autarky” and do not trade with each other or with anyone else. People in Village A consume 100 bottles of (W) and 20 bottles of...

On a laboratory table there are 6 bottles containing 6 halides, but the labels were lost. Bottle A is a white solid, bottle B is a deep red solid, C is a colorless gas, D is a solid formed by violet flakes, E is a colorless liquid and F is broken (had a explosive product). A, B, C, D, E y F?

Write a program that displays a frame containing two labels that display your name, one for your first name and one for your last. Experiment with the size of the window to see the labels change their orientation to each other. USE FIRST NAME: Aya LAST NAME: KAYED. SEND THE CODE IN THE EXACT FORMAT FOR JAVA ECLIPSE. I WILL COPY AND PASTE THE CODE SO I CAN RUN IT.

A firm has a possibility to produce output using either one or two units of capital. Capital costs $10 per unit. Labor is always variable. If it uses 1 unit of capital, marginal cost is constant (no diminishing returns) at $3. If it uses 2 units of capital, marginal cost is constant at $1. For the output quantities of 1 to 10, create the firm’s short run average total cost curves. Also create the firm’s long-run average total cost curve....

A student can enter a course either as a beginner (73%) or as a transferring student (27%). It is found that 62% of beginners eventually graduate, and that 78% of transfers eventually graduate. Find: the probability that a randomly chosen student is a beginner who will eventually graduate, the probability that a randomly chosen student will eventually graduate, the probability that a randomly chosen student is either a beginner or will eventually graduate, or both. Are the events ‘eventually graduate’...

6. An evil king has n bottles of wines, and a spy has just poisoned one of them. Unfortunately, they do not know which one it is. The poison is very deadly; just one drop diluted even a billion to one will still kill. Even so, it takes a full month for the poison to take effect. Design a scheme for determining exactly which one of the wine bottles was poisoned in just one month’s time while expending O(log n)...

All of this is considered one question, but I tried to seperate them. Read President George W. Bush’s State of the Union Address. Then answer the questions that follow on a separate sheet of paper. 1. What sentence states the main idea? 2. What other clues do you find to help you identify the main idea? 3. In one sentence, state the writer’s main point in your own words. 4. What details does the writer use to support the main...
