10.   If a car travels from Town A to Town B on one road at different speeds and stops at red lights, knowing the distance between the towns and the total time of the trip can allow you to calculate     A. instantaneous velocity.B. deceleration.C. average velocity.D. uniform velocity.

The strength of intermolecular forces of attraction varies depending on the type of molecules involved. In general, the order of increasing strength of intermolecular forces is as follows:

1. **London Dispersion Forces (Van der Waals Forces):** These are the weakest intermolecular forces and occur in all molecules. They are caused by temporary fluctuations in electron distribution, leading to temporary partial charges. London dispersion forces are stronger in larger and more polarizable molecules.

2. **Dipole-Dipole Forces:** These forces occur between polar molecules with permanent dipoles. They are stronger than London dispersion forces and result from the attraction between the positive end of one molecule and the negative end of another.

3. **Hydrogen Bonding:** This is the strongest type of intermolecular force. It occurs when hydrogen is bonded to a highly electronegative atom (such as nitrogen, oxygen, or fluorine) and is attracted to another electronegative atom in a different molecule. Hydrogen bonds are responsible for the unique properties of substances like water and ammonia.

So, hydrogen bonding generally represents the strongest intermolecular force of attraction among these three types. However, it's important to note that the actual strength of these forces can also depend on factors such as molecular size, shape, and temperature.

Answer: a)

b) 92.1 g

Explanation:

To calculate the moles, we use the equation:

a) moles of

b) moles of

According to stoichiometry :

1 mole of require 2 moles of

Thus 1.173 require=  of

Thus is the limiting reagent as it limits the formation of product. Thus will run out first.

is the excess reagent as (3.500-2.346)= 1.154 moles are left unreacted.

2 moles of require 1 mole of

3.500 moles of require= of

Moles of  required = (1.750-1.173) = 0.577

Mass of

Thus he should order 92.1 g of the limiting reactant.

Answer:

Explanation: Over pumping refers to pumping fresh water and reducing the level of an underground layer of water. In coastal areas, the lower underground layer of water is infiltrated with salt water, eventually increasing the salinity of the underground layer of water to the point that it is not drinkable. The scarcity of water in the coastal areas because the water in the coastal areas is not drinkable.
