Answer: a common ion of xenon is fluoride-ion. xenon oxide difluoride is also a fluoride-ion acceptor, forming the only other anion containing xenon in the +4 oxidation state, the XeOF3− anion in Cs+XeOF3−. Xenon hexafluoride is both a strong fluoride-ion donor and a strong fluoride-ion acceptor.
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.
Explanation:
The reaction is at dynamic equilibrium.

(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.

C. matter658 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

What mass of KBr (in grams) do you need to make 250. 0 mL of a 1. 50 MKBr solution?.
Answer:
KBr final solution:
V = 250mL --> 0.25L
Concentration/Molarity = 1.5 mol/L
To find the amount of moles of KBr here, just multiply the volume by the concentration (0.25 x 1.5 = 0.375 mol)
So the amount of moles for KBr is 0.375 mol. Now we know that the mass divided by the molar mass (the atomic mass values of K and Br in the periodic table added together) would give us the amount of moles aswell.
n = moles
m = mass
M = molar mass
n = m/M
so if we rearrange this equation to find mass, we would get:
m = n x M
Molar mass for KBr: (39.09) of K + (79.90) of Br = 118.99
m = 0.375 mol x 118.99
m = 44.62g
Therefore 44.62g of KBr is needed to make 250mL of a 1.5 M KBr solution.

The equation for a base solution is B + H2O = BH+ + OH- The strength of the base in a solution is increased. How
will the number of particles change? (1 point)
O The number of B molecules will increase, and the number of OH ions will decrease.
The number of BH molecules will increase, and the number of water molecules will decrease.
The number of OH-ions will increase, and the number of BH molecules will decrease.
O The number of B molecules will increase, and the number of water molecules will decrease.
Answer:The number of BH+ Molecules will increase , and the number of water molecules will decrease
Explanation:
The number of OH- ions will increase, and the number of BH molecules will decrease.
Option (3) is correct.
In the given base solution equation, B + H₂O = BH⁺ + OH⁻, when the strength of the base is increased, more B molecules will react with water to form BH⁺ and OH⁻ ions. This happens because a stronger base donates more OH⁻ ions into the solution, increasing its concentration.
As the base becomes stronger, more B molecules will participate in the reaction, forming fewer BH⁺ molecules since they are being converted to BH⁺ ions. Simultaneously, the increased concentration of OH⁻ ions means that the number of OH⁻ ions in the solution will increase.
Overall, the change in the number of particles can be summarized as follows:
The number of BH molecules will decrease.
The number of OH⁻ ions will increase.
This change reflects the increase in the concentration of OH⁻ ions, which is a characteristic of a stronger base solution.
