Answer:
Cohesive forces are greater than adhesive forces
Step-by-step explanation:
The attractive forces between water molecules and the wax on a freshly-waxed car (adhesive forces) are quite weak.
However, there are strong attractive forces (cohesive forces) between water molecules.
The water molecules are only weakly attracted to the wax, so the cohesive forces pull the water molecules together to form beads

Answer:
Lots of things here
Explanation:
Ammonia structure is written as NH3
carbon monoxide is CO
make bonds between O2, so there is 2 oxygen atoms per group,
anything with multiple elements bonded is a compound, thus your answer for carnon monoxide isnt correct, it should be CO for written and it is a compound. Fix your formula for ammonia and also max a bond between those two oxygens because it is O2 not O,
Your structure for SO2 is improper aswell, there are only 3 elements in this molecule, and usually the one out in front of the molecule is the central atom (except hydrogen). So it would go O-S-O for the structure, with only two bonding groups.
Answer:
from the way I understand the question I think the answer is (B)
Explanation:
Because the distribution into shells of oxygen is 2,6 and in sulfur is 2,8,6 and oxygen has a 8th number of electrons and sulfur has the 16th number of electrons
