Answer:
they gain enough energy to break away from the bonds that keeps them a liquid
also the particles diffuse away
Explanation:
When liquid bromine evaporate,
Then space or distance between its particle increases.The bromine particles start moving freely when it evoporates .The inter-molecular force of attraction between particles is increases when liquid bromine evaporates.Why liquid bromine easily evaporates?The liquid bromine easily evaporates because of following reasons:
The liquid bromine is more denser then water.Its melting and boiling point is -7°C and 58.9°C.The liquid bromine present in the form liquid at room temperature that is why it is easy evaporates.To learn more about liquid bromine,

an inexperienced student adds a solution of catalytic h2so4 and water to the alkene shown below, expecting to produce 1-cyclobutylethan-1-ol.
The rearrangement produces a more stable tertiary carbocation and the unexpected product.
In the image shown, the substrate is 1-cyclobutylethene. The attack of H2SO4 and water will lead to the conversion of the alkene to an alkanol. Two possible products may be obtained with one being greater than the other.
The unexpected product (Shown in the image attached) is obtained due to rearrangement of the carbocation intermediate. The rearrangement produces a more stable tertiary carbocation and the unexpected product.

What volume of 0.205 MK2S solution is required to completely react with 185 mL of 0.120 MCo(NO3)2?
Answer:
the balanced equation for the above reaction is as follows;
3NiCl₂ + 2K₃PO₄ ---> Ni₃(PO₄)₂ + 6KCl
stoichiometry of NiCl₂ to K₃PO₄ is 3:2
the number of NiCl₂ moles reacted - 0.0102 mol/L x 0.134 L = 0.00137 mol
according to molar ratio
if 3 mol of NiCl₂ reacts with 2 mol of K₃PO₄
then 0.00137 mol of NiCl₂ reacts with - 2/3 x 0.00137 = 0.000911 mol of K₃PO₄
molarity of given K₃PO₄ solution - 0.205 M
there are 0.205 mol in 1000 mL
therefore volume of 0.000911 mol - 0.000911 mol / 0.205 mol/L = 4.44 mL
volume of K₃PO₄ needed is 4.44 mL

Find the percent by mass concentration if the solution was prepared by dissolving 25.0 g of sugar into 100 g of water.
Answer:
25%
Explanation:
Percent by mass is looking at the percentage of mass within a a solution. So since there's 100g of water and 25 grams of sugar, you divide 25 by 100 to get the ratio. Then multiply by 100 to get the percentage.

why are there no elementary substances that have the ionic bond?
This problem is asking for the reason behind the nonexistence of elementary substances with ionic bonds. First of all, it is necessary to bear to mind that the definition of the type of bond in a compound depends on the difference electronegativity that is present between two of the atoms composing it.
For instance, in binary salts, such as KCl, NaCl, KBr and so on, we are able to know these are all ionic because they are composed by a metal and a nonmetal, which have the smallest and largest electronegativities, so that the difference electronegativity is large enough to produce an ionic bond.
In contrast, elementary susbtances, such as liquid bromine (Br2) and gases such as H2, N2, Cl2, F2 and O2, since they are all nonmetals and the same type, the electronegativity difference will be 0 and therefore, they will not be ionic but covalent.

Answer:
The nucleus has an overall positive charge as it contains the protons.
Explanation:
Every atom has no overall charge (neutral). This is because they contain equal numbers of positive protons and negative electrons. These opposite charges cancel each other out making the atom neutral.

How much aluminum can be extracted from 3.5 metric tons of bauxite ore which is 70% aluminum oxide?
Answer:
A) 17.5%
B) 1) 2135 kg
2) 375 kg
C) 91.8
Explanation:
Part (A):
1 tonne= 1000 kg= 100%
Aluminium oxide= 825 kg= 82.5%
Iron (lll) oxide= 100 kg= 10%
Sand= 85 kg= 7.5%
That makes total of 100%
So, the percentage of impurities= Iron (lll) oxide + Sand
=> 10 + 7.5= 17.5%
Part (B):
(1) 1 tonne= 427 kg
Multiplying both sides by 5
=> 5 tonne= 427 * 5
=> 5 tonne = 2135 kg
(2) 1 tonne contains 75 kg sand as impurity
=> 1 tonne= 75 kg
Multiplying both sides by 5
=> 5 tonnes = 75 * 5
=> 5 tonnes = 375 kg
Part (C):
If all of the iron oxide was removed, then only aluminium and sand are left.
Aluminium = 825 kg
Sand= 74 kg
Total of them makes it:
=> 825 + 74 = 899
So,
% age of Aluminium= 825/899 * 100
% age of Aluminium= 0.918 * 100%
% age of Aluminium= 91.8%

Would results of solubility of sugar dissolving in water change if a person used a different solute?
Answer:
If a solute is a solid or liquid, increasing the temperature increases its solubility. For example, more sugar can dissolve in hot water than in cold water. If a solute is a gas, increasing the temperature decreases its solubility. For example, less carbon dioxide can dissolve in warm water than in cold water.
