Can you help me every step by step with number 3 part A,  part B, part C, part D? Can you explain it to me?

The following reversible enzymatic reaction occurs in many areas of the body, but especially in red blood cells. The conversion of water and carbon dioxide into bicarbonate and hydrogen ions occurs through the action of an enzyme called carbonic anhydrase. Use the Law of Mass Action to predict which direction this equation will go under different circumstances. CO2 + H2O ↔  H+ + HCO3- Hyperventilating would increase the loss of carbon dioxide (CO2) from the blood. In what direction would the reaction above go in order to restore equilibrium? Left or right?

3. For the following reaction, write how the each of the changes will affect the indicated quantity, assuming a container of fixed size. Write "increase", "decrease", or "no change". (Or use an "up" arrow to indicate "increase", and a "down" arrow to indicate "decrease".) (For a chemical added, write how it would respond AFTER the addition.)

The temperature is decreased 7. Pressure is increased and the container volume decreased

4 o When burning ethanol in a closed system, which of the following is the best claim and reasoning? The ethanol reaction stops because a bromthymol blue solution that's present turns the same color as when ethanol vapor is blown into the solution. O Water is produced because a bromthymol blue solution that's present turns the same color as when water vapor is blown into the solution. O Evaporated ethanol is produced because it burns. Carbon dioxide is produced because a bromthymol blue solution that's present turns the same color as when carbon dioxide is blown into the solution. 1 2 4. 6 7 8 Next acer

18) In one of your experiments, you used a Grignard reaction to make a carboxylic acid. „Br 1) Mg 2) CO2 As part of this experiment, the following procedures were given: 1. When the Grignard reaction begins to slow down, place 10 g of crushed dry ice in a 150 mL beaker. Do not take time to weigh the dry ice. Use approximately the amount in the beaker indicated by your instructor. The CO2 is in large excess and will not affect your calculation of percent yield of benzoic acid product. Cover the beaker with a watch glass. 2. When most of the magnesium has reacted and the ether boiling subsides, quickly pour the contents of the tube into the beaker containing dry ice. 3. Add a few milliliters of ether to the test tube and swirl to rinse. Add the rinse liquid to the beaker. 4. Cover the beaker with the watch glass and allow it to stand until the next lab period. During the interim, the excess dry ice will have sublimed. 5. Hydrolyze the Grignard addition product by slowing adding 30 mL of…

Hi!  I just wanted to make sure I'm thinking about this one correctly. A reaction at equilibrium means reactants and products are consumed and formed at the same rate? Or am I thinking about it wrong?

Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is exothermic. Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other. For example, if one energy is less than another, that fact should be clear in your sketch.

Sketch a qualitative reaction energy diagram for a chemical reaction with and without a catalyst. Assume the uncatalyzed reaction is endothermic. Note: Because the sketches are only qualitative, the energies in them don't have to be exact. They only have to have the right relationship to each other.

Convert each "b" value from the three Graphs ln(Conc) to the Initial Concentration. Graph Two:  y= -0.0048x -11.125 Graph Four: y= 161824x - 13.326  Graph Five: y= -0.0189x -10.903  **Note these are the y= mx-b equation from the linear graph,  In(concentration) vs time. I don't know how to convert natural log value such as -11.125 to the initial concentration.

A student wants to know how many grams of water are made from 5.00 grams of oxygen gas during the synthesis of water from basidelements. Which step should be substituted for the question marks? 2 Hz+ O2→2 H;0 5.0 g 02 1.0 moles 0, 1 31.998 g 02 18 g H,0 A. 1.0 mole 0, 2.0 mole H,0 B. 1.0 mole 0, 18 g H,0 C. 2.0 mole H,O 2.0 mole 0 D. 2.0 mole H, O

Diagrams like the one below are used to represent exothermic reactions. For instance, consider burning charcoal (which almost entirely pure element carbon). A=carbon and B=oxygen, when they react they form C=carbon dioxide. A little chemistry vocab: do substances (A + B) in the diagram represent the reactants or the products? A+B Activation Energy Reaction Progression Energy

Analyze, whether the given situation increase or decrease, then explain why?

Consider the reaction where the reactants are converted to the products. HC=CH + NH3 "reactants" "products" The dotted arrow is a placeholder. Select the descriptor that best describes the relationship between the "reactants" and "products". The arrow should be: NH₂+ + HC

Any chemical or physical change that absorbs energy is an endothermic process. is an exothermic process. has high activation energy. is a catalyzed process.
