Yes; this is done in chemistry labs all the time!You can prepare a dilute solution (which has a low molarity; a lower concentration of H3O+, hydronium ions) of a strong acid (a low molarity) by placing a small amount of the concentrated acid in a larger amount of water.
Absorbance rises with concentration because there is more material for a given frequency of light to be absorbed in. Your statement is false.
True. In an aqueous solution of ionic compounds, the positive and negative ions will attract each other due to their opposite charges, forming electrostatic bonds known as dipole attractions.
True. Vinegar contains acetic acid which can dissolve the calcium carbonate in limestone, making it possible to separate the fossils from the limestone.
True. A concentrated solution can be made more dilute by adding more solvent, which increases the volume of the solution and decreases the concentration of the solute. This process effectively reduces the ratio of solute to solvent, resulting in a less concentrated solution.
The statement is true. Solvent is what you dissolve a solute in. In chemistry, your solvent is usually going to be water. So, if you have a concentrated solution and you pour some more water into it, you're diluting the solution.
