Hydrocarbons | FPan, MVCC 3. Now you have built an isomer of butane: same formula but different structures of butane. Let's construct models of all 4 isomers of hexane (CHu), and draw only the carbon backbone. (Note: identical structure may be constructed without knowing How can you tell? One simple method is to name them and see if they share the same name.) Structural Diagram Name 4. Build a hydrocarbon molecule that has ethyl group as a substituent on the main carbon chain. The ethyl group must retain its identity and cannot be part of the longest chain if its name is to appear in the name of the compound. Name and draw the structure you have built. Name wp amanus

Determine the structures of the missing organic molecules in the following reaction: Y II OH X + H₂O H+ H* OH Note: Molecules that share the same letter have the exact same structure. In the drawing area below, draw the skeletal ("line") structures of the missing organic molecules X and Y. You may draw the structures in any arrangement that you like, so long as they aren't touching. Click and drag to start drawing a structure. C X :0 Ś m c+

The name carbohydrate comes from the fact that many simple sugars have chemical formulae that look like water has simply been added to carbon. (The suffix hydrate from the Greek word hydor ("water") means "compound formed by the addition of water.") The actual chemical structure of carbohydrates doesn't look anything like water molecules bonded to carbon atoms (see sketch at right). But it is nevertheless possible to chemically extract all the hydrogen and oxygen from many simple carbohydrates as water, leaving only carbon behind. If you search the Internet for "reaction of sulfuric acid and sugar" you will find some impressive videos of this. Suppose you had  300.g  of ordinary table sugar, which chemists call sucrose, and which has the chemical formula  C12H22O11 . Calculate the maximum mass of water you could theoretically extract. Be sure your answer has a unit symbol, and round it to the correct number of significant digits.

DNA, or deoxyribonucleic acid, is the hereditary material in humans and almost all other organisms. It contains the biological instructions that make each species unique. DNA, along with the instructions it contains, is passed from adult organisms to their offspring during reproduction. Nearly every cell in a person's body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA). The information in DNA is stored as a code made up of four chemical bases: adenine (A), guanine (G), cytosine (C), and thymine (T). Human DNA consists of about 3 billion bases, and more than 99 percent of those bases are the same in all people. The order, or sequence, of these bases determines the information available for building and maintaining an organism, similar to the way in which letters of the alphabet appear in a certain order to form words and sentences. DNA bases…

4 Why would the chemical equation 1 B2(CO3)3 →1 B2O3+3 CO2 be considered “wrong”?

Given the following data: 2 H₂(g) + O₂(g) → 2 H₂O(g) C₂H4(g) + 3 O₂(g) → 2 CO₂(g) + 2 H₂O(g) 2 CzHo(g) +7 Oz(9) → 4 CO,(g) + 6 H20(g) calculate AH for the reaction C₂H₂(g) + H₂(g) → C₂H₂(g). kJ ΔΗ = −484 kJ AH-1323 kJ ΔΗ = -2857 kJ

You are a forensic scientist. You are investigating a murder involving poison. The victim was poisoned with a compound called di-chlorobenzene, whose formula is C6H4Cl2. Autopsy results show that the victim’s body contained about 27.5 g of the poison, but the actual amount could have been slightly higher due to tissue absorption. The main suspect is his wife, Suzanne, who works as a chemistry professor. Records show that she purchased 15 g of benzene (C6H6) two days before the murder. Benzene is one of the compounds use to make the poison. She claims she was using it to make methyl benzene (C6H5CH3), an innocuous compound, for use in her lab. She shows you the bottle of methyl benzene she claims to have made. It contains 25 g of methyl benzene. To produce di-chlorobenzene, the reaction is:       Cl2(g)  +  C6H6(l) ⟶⟶ C6H4Cl2(l) + H2(g) To produce methyl benzene, the reaction is:          CH4(g) + C6H6(l) ⟶⟶ C6H5CH3(l) + H2(g)   Use stoichiometry to solve this case.
