liquid bromine easily evaporates. explain what happens to the particles when a liquid evaporates
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,

658 mL of 0.250 M HCl solution is mixed with 325 mL of 0.600 M HCl solution. What is the molarity of the resulting solution
The molarity of the resulting solution obtained by mixing 658 mL of 0.250 M HCl solution with 325 mL of 0.600 M HCl solution is 0.366 M
We'll begin by calculating the number of mole of HCl in each solution. This can be obtained as follow:
For solution 1:Volume = 658 mL = 658 / 1000 = 0.658 L
Molarity = 0.250 M
Mole of HCl =?Mole = Molarity x Volume
Mole of HCl = 0.250 × 0.658
Mole of HCl = 0.1645 moleFor solution 2:Volume = 325 mL = 325 / 1000 = 0.325 L
Molarity = 0.6 M
Mole of HCl =?Mole = Molarity x Volume
Mole of HCl = 0.6 × 0.325
Mole of HCl = 0.195 moleNext, we shall determine the total mole of HCl in the final solution. This can be obtained as follow:Mole of HCl in solution 1 = 0.1645 mole
Mole of HCl in solution 2 = 0.195 mole
Total mole = 0.1645 + 0.195
Total mole = 0.3595 moleNext, we shall determine the total volume of the final solution.Volume of solution 1 = 0.658 L
Volume of solution 2 = 0.325 L
Total Volume = 0.658 + 0.325
Total Volume = 0.983 LFinally, we shall determine the molarity of the resulting solution.Total mole = 0.3595 mole
Total Volume = 0.983 L
Molarity =?Molarity = mole / Volume
Molarity = 0.3595 / 0.983
Molarity = 0.366 MTherefore, the molarity of the resulting solution is 0.366 M

The reaction is at dynamic equilibrium.
N2 + 3H2 ⇌ 2NH3
Which statement is correct?
(1 point)
The solution has the same concentrations of nitrogen gas and ammonia.
The solution has the same concentrations of nitrogen gas and ammonia.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
The solution has the same concentrations of nitrogen and hydrogen gases.
The solution has the same concentrations of nitrogen and hydrogen gases.
Both directions of the reaction have stopped.
Both directions of the reaction have stopped.
Considering the definition of dynamic equilibrium, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.
Chemical equilibrium is a state of a reaction in which no changes are observed as time passes, even though the reaction continues. That is, the chemical equilibrium is established when there are two opposite reactions that take place simultaneously at the same speed.
So, dynamic equilibrium is a chemical equilibrium, which occurs when two reversible processes happen at the same speed in both directions. In this way, the concentrations of the reactants and products remain constant over time.
In summary, the correct answer is second option: Nitrogen and hydrogen combine at the same rate that ammonia breaks down.

Write the balanced chemical equation for the following reaction. Also, classify the
reaction as sythesis, decomposition, single replacement, double replacement, or combustion.
aluminum sulfate + barium chloride —> aluminum chloride + barium sulfate
Answer:
Reaction: Al2(SO4)3 + 3BaCl2 --> 2AlCl3 + 3BaSO4
Type: Double Replacement
Explanation:
1.) First you need to understand what the different reactions are
a.) Synthesis: is a reaction where two or more substances will combine with each other to make one product.
Ex: A + B → AB
b.) Decomposition: when one compound breaks down into two or more substances. (Opposite of synthesis)
Ex: AB → A + B
c.) Single Replacement: when one element replaces another one in a reaction
Ex: A + BC → AC + B
d.) Double Replacement: when the positively charged cations and negatively charged anions of the reactants trade places. Normally this will be the two outer elements combining and the two inner ones combining.
Ex: AB + CD → AD + CB
e.) Combustion: when a substance reacts with oxygen gas and releases energy as light and heat.
Ex: CH4(g) + 2 O2(g) → CO2(g) + 2 H2O(g)
2.) From there you can write out the formula of the different reactants and products and balance the equation.

what happens to the particles of a solid as it becomes a liquid
Answer:
melting
Explanation:
Answer:
When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Further heating provides more energy until the particles start to break free of the structure. Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid.
