1. Which solution represents a dynamic equilibrium? 2. In a saturated solution, the rate of crystallizing is • the rate of dissolving. 3. In a saturated solution, the forward reaction rate is + the reverse reaction rate. 4. In a saturated solution, there is in the amount of product and starting material. 5. When a chemical system is at dynamic equilibrium, there visible changes in the system.

Shown here is a tripeptide, which consists of three amino acids linked together in a chain. Circle and name each amino acid. HO H,N HO

at a pH value of 2, the amino and carboxyl groups in an amino acid will exist as

Please help me with the following 1) sketch a phosphodiester bond 2) Make the two amino from the image below. And contrast the polarity of the side chains

Amino acids are synthesized by plants to store nitrogen. True or false.

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.
