If the object has an irregular shape, the volume can be measured using a measuring cylinder or a displacement can
Answer:
Explanation:
1st) one are homogenous because the have the same kind of force 9 London force ) all the hydrocarbons are nonpolar and have a London force between their molecules
so pentane dissolve in hexane (like dissolves like )
2nd ) CBr4 has a tetrahedral shape its a nonpolar compound (London bond )
but the water is polar molecules has a ( hydrogen bond ) its molecular shape (bent shape) . Both do not dissolve in each other because they have a different kinds of bond so they are <u>not a homogenous solution </u>.
3rd) its a homogenous because the water can dissolve the ionic bonds between the Li ( cation ) and (NO3 -1 anion ).
4th ) here we can say alcohol can dissolve in a little amount why ?
- pentane has a London force bond
- Alcohol has two different parts first part has OH making hydrogen bond which cant dissolve in the pentane different kinds of bonds ,and the other part -CH3 has a London force bond that can dissolves easily in the pentane
- so one part dissolves but the other part can't dissolve so the two compound are slightly dissolves in each other that which mean its <u>not a homogenous solution </u>

Answer:
Each colour has a purpose. Black is generally used for insulating wires. Other colours are known as 'phasing tapes'. These colours indicate the voltage level and phase of the wire.
Explanation:
<span>The best answer among
the choices is the first option. The chemical property of soda is that it is a
highly basic substance. It's chemical name is sodium carbonate. It is more
basic than sodium bicarbonate. Adding soda ash in a solution would increase the
pH of the solution.</span>
