Cammie wonders whether hydrogen bonds would form if water molecules had a linear shape, with the oxygen atom in between the two hydrogen atoms.
Which statement best answers Cammie’s question?
a) A straight molecule would not be able to form hydrogen bonds because the oxygen atom would pull electrons equally from both hydrogen atoms, and the molecule would have no polarity overall.
b) A straight molecule would still be able to form hydrogen bonds because the hydrogen atom at one end would be slightly negative and the hydrogen atom on the other end would be slightly positive.
c) A straight molecule would not be able to form hydrogen bonds because the electrons would be shared equally between the oxygen atom and the hydrogen atoms.
d) A straight molecule would still be able to form hydrogen bonds because the oxygen atom would still pull harder on the shared electrons than the hydrogen atoms.

Aperson gives a shopping cart an initial push along a horizontal floor to get it moving, and then lets go. the cart travels forward along the floor, gradually slowing as it moves. consider the horizontal force(s) on the cart while it is moving forward and slowing. which of the following statements is correct? (a) both a forward and a backward force are acting on the cart, but the forward force is larger. (b) only a forward force is acting which diminishes with time. (c) both a forward and a backward force are acting on the cart, but the backward force is larger. (d) only a backward force is acting, no forward force.
