Answer:
They allow particles to stay close together.
The attractive forces (bonds) in a liquid are strong enough to keep the particles close together, but weak enough to let them move around each other. For example, Liquids are useful in car brake systems because they flow and cannot be compressed.

Answer: Odor of ammonia would we detect first on the other side of the room.
Explanation:
To calculate the rate of diffusion of gas, we use Graham's Law.
This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows:
Thus the odor of ammonia would we detect first on the other side of the room as the rate of effusion of ammonia would be faster as it has low molecular weight as compared to hydrogen sulphide.
Answer:
A. 2.9*10^24
B. 3.4*10^21
C. 1.2*10^25
D. 1.7*10^23
Explanation:
1 mol of any particle has 6.02*10^23.
A. 4.8 mol Cu* 6.02*10^23 (1/mol) ≈2.9*10^24
B. 5.6x10^-3 mol C *6.02*10^23 (1/mol) ≈3.4*10^21
C. 20.0 mol Hg*6.02*10^23 (1/mol)≈1.2*10^25
D. 0.285 mol Na*6.02*10^23 (1/mol)≈1.7*10^23
C pretty sure if not sorry
