What would likely happen if a hot saturated solution were filtered by vacuum filtration using a büchner funnel? (hint: the mixtu

re will cool as it comes in contact with the büchner funnel.)?

<span>The saturated HOT solution is filtered it then rapidly cools due to evaporation under vacuum. When it cools, the solution becomes supersaturated and usually precipitates since it cools too rapidly to crystallize nicely. As it precipitates, it clogs usually the funnel. Worse yet as when clogs the filter, our solution sits in the top of the funnel stuck</span>

What has the lowest ionization erergy?
Svetach [21]

Answer:

Francium (Fr)

Explanation:

From the given choices, francium will have the lowest ionization energy.

Ionization energy is the energy required to remove the most loosely held electron within an atom.

The magnitude of the ionization energy depends on the characteristics of the atom in relation to its nuclear charge, atomic radius, stability etc.

  • Generally on the periodic table, ionization energy increases from left to right on the table
  • As you go from metals to non-metals and to gases, the value of the ionization energy increases steadily.
  • Down the group, the value reduces.
  • Since Francium is the most metallic of all the given choices, it has the highest ionization energy.

Explanation:

they tell you how many atoms there are of its type.

ex. 4 C²H³. there are 4 of the c² and h³ (couldn't find a way to use subscript so used the power signs to show.)

Ions that are made of more than one atom are examples of
anastassius [24]
These ions are polyatomic ions. The prefix "poly-" means "many," and the rest of the word "atomic" clearly refers to the atoms themselves. So, if there are two or more atoms in an ion, this ion is polyatomic.
