Question

26. A dehydration synthesis reaction between glycerol and a single fatty a) micelle e) monoglyceride e) triglyceride b) omega-3 faty acid d) diglyceride 27. If an element is composed of atoms with an atomic number of 6 and a mass nuamber of i4, then a neutral atom of this element contains a) 6 protons c) 8 electrons e) 14 electrons b) 6 neutrons d) 14 protons 28. One mole of any element )has the same mass b) has the same weight has the same number of atoms ) has the same number of electrons e) all of the above 29. When clectrons are transferred from one atom to another, and the two atoms unite as a resalt of the electrostatic attraction, a) an ion is formed c) a hydrogen bond is formed e) a covalent bond is formed b) a molecule is formed d) an ionic bond is formed 30, Calcium atoms have two electrons in the outermost shell. As a result, you would expect calcium to form ions with a charge of a) +1 b) +2 d)-2 e) none of the above

Explanation / Answer

26.C) A dehydration reaction between gycerol and single fatty acid would yield a monoglycerid.

27.c) 8 ( Mass number - atomic number i.e. 14 -6 =8 )

28.c) One mole of any element has same number of atoms of that element.

29. d) An ionic bond is formed when electrons are transferred from one atom to another and the two unite as a result of opposite or electrostatic attraction.

30. b) (+2) Calcium atom will lose 2 electrns and will form Ca2+ ion.
