Question

28. Type of chemical bond in which electrons are shared by two atoms: a.hydrogen b. ionic c. isotopic d. electronic valent 29. Water is said to be a polar compound because the shared electrons spend more time around the oxygen than the hydrogen atoms false 30. What is the concentration of 306 grams of glucose (molecular weight 180 g/mol) placed in 200 ml of water? a. 1.0 molliter b. 10 mol/liter c. 0.1 mol/liter d. 0.04 mo/liter 30 31. The breakdown of fats (triglycerides) into free fatty acids is an example of a. an anabolic reaction exergonic reaction a reaction that requires energy d. (a) and (b) are correct e. (a) and (c) are correct 32. The rate of chemical reaction may be affected by: a. presence of enzymes b. concentration of reactants c. concentration of products temperature e) all of these 33. When the following reactions are at equilibrium: a. more water is formed than H and O

Explanation / Answer

30. 306/180 * 1000/200

= 8.5 mol/ l

May be weight is printed wrong, if it is 360 instead of 306, value will be 10 mol/ l.
