The correct option is C.
The density of an object refers to its mass per volume. Water and ice have different densities. The differences in their densities is due to the empty spaces which exist in the structure of ice. Because of the empty spaces, the structure of ice occupy more volume than that of water, hence it is less dense than water.
Answer:
Add, reduce
Explanation:
Concentration is essentially a ratio of the amount of solute to the amount of solvent.
\text{Concentration} = \dfrac{\text{amount of solute}}{\text{amount of solvent}}
If you want to make a solution more dilute (less concentrated), you must do one of two things:
- Increase the denominator — add solvent
- Reduce the denominator — reduce the amount of solute
A is wrong. If you add both more solute and more solvent, the concentration will stay about the same.
B is wrong. If you add more solute and reduce the amount of solvent, the concentration will increase.
D is wrong. If you add more solute and do nothing to the amount of solvent, the concentration will increase.
Answer:
where is the question here
You would do 82.75 divided by 125 cm3 and get 0.6620 g/cm3 because to find density you mist divide mass and volume and grams is always mass and cm3 or mL is always volume. hope i helped!
In electroplating with silver, silver cyanide is used in the electrolyte rather than other compounds of silver such as silver nitrate, AgNO3, because the cyanide ion, CN-, reacts with silver ion, Ag+, to form the complex ion Ag(CN) -.
