P=0.0902 g/l
v=22.4 l/mol (stp)
M=vp
M=22.4 l/mol * 0.0902 g/l=2.020 g/mol
M=2.020 g/mol
The answer is <span>ionic aluminum fluoride (</span>AlF3). Note that boiling points of pure solvents are raised in the presence of solutes. The type of solute also affects the boiling point elevation of the solution. Ionic substances tend to raise it more than covalent ones, so sucrose is out of the picture. Next, consider the number of ions the ionic substance produces. The more ions, the greater the BPE. AlF3 dissociates into 4 ions.
Answer:
It is (A.) Gases have the highest kinetic energy, followed by liquids, and then solids
Explanation:
<u>Gases have high kinetic energy</u> because their particles are far apart from each other and have a negligible force of attraction, whereas <u>Liquids have the high force of attraction as compared to gases so they have less kinetic energy than gases</u>, and <u>Solids have the high force of attraction between their particles</u> because of that its molecules are closely packed, therefore
<u>Gases have the highest kinetic energy,</u>
<u />
<u>Followed by Liquids,</u>
<u />
<u>Then finally, Solids with the lowest kinetic energy.</u>
A force is a push or a pull.
Explanation:
Force is what is moving an object. An example could be gravity. It is a force that pulls us towards the earth.
