Answer:
Explanation:
They play a very important part. The geometry is not a straight line. It is an angle over 90 which means that the molecule has the same general shape as a boomerang. The two hydrogens and the 2 lone electron pairs try to get away as far as possible from each other. The actual shape results in a tetrahedron shape. But the two hydrogens and 1 oxygen actually look like the aforementioned boomerang.
Answer:
Picking up marbles and placing them in a sack
Explanation:
The entropy of a chemical system is defined as the measure of disorder. Therefore a negative change in entropy is the movement to a more ordered state. The only option here which achieves a more ordered state, would be the first option.
Picking up marbles and placing them in a stack achieves more order, rather than the other options - that achieve more disorder.
