The answer is (in
order from strongest to weakest);
<span>covalent </span>
<span>ionic </span>
ion-dipole
H-bonding
dipole-dipole
<span>van der Waals</span>
A covalent<span> bond is
hardest to break because it involves sharing of electrons by atoms while Van der
Waals is weakest because they involve electrostatic
attraction due to differentially induced
dipoles between atoms and its strength is dependent
on their distance apart. </span>
The correct answer is a Forward reaction to slow.
According to Le Chatelier's principle as the reactant decrease so the reaction should go leftward and this is called backward or reverse reaction so the reverse reaction will be fast to achieve equilibrium and the forward reaction will be slow.
Answer:
D. <span>10 mol of solute/ 1L of solution
Explanation:
Molarity is used to express the concentration of the solution. It is expressed as the number of moles of solute per liter of solution
Molarity = moles of solute / liters of solution
This means that molarity has the units moles/liter
The only option satisfying this is the last one.
Hope this helps :)</span>

Answer: Groundwater that forms caves because it is slightly acidic.
Explanation:
The water under the ground present inside the cracks and spaces in sand, soil and rocks is called ground water.
When ground water moves through the soil it results in the formation of acid. Further, this acid helps minerals to get dissolve. These minerals get deposited on other places as well.
This process of deposition and erosion helps in the formation of caves.
Thus, it can be concluded that groundwater that forms caves because it is slightly acidic.
