La energía cinética está relacionada con la velocidad de las partículas.
Sabemos que la velocidad de las moléculas de gas depende de la temperatura del cuerpo. La temperatura de un cuerpo es una medida de la energía cinética promedio de las moléculas del cuerpo.
Debemos notar que cuanto mayor es la temperatura del cuerpo, mayor es la velocidad de sus moléculas. Por lo tanto, a una temperatura de 10,000,000 ° C, las moléculas en el núcleo del sol tienen una velocidad mayor que las moléculas en la superficie del sol.
Todas las moléculas, ya sea en el núcleo o en la superficie del sol, se mueven a mayor velocidad que las moléculas de la limonada a una temperatura mucho más baja. La energía cinética está relacionada con la velocidad de las partículas.

How many grams of barium chloride are produced when 1.25 x 1023 molecules of HCl reacts with barium?
Considering the reaction stoichiometry and Avogadro's Number, the mass of barium chloride produced is 21.6 grams.
Balanced reaction
The balanced reaction is
2 HCl + Ba → BaCl₂ + H₂
Moles of HCl that reactAvogadro's Number is called the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023×10²³ particles per mole. Avogadro's number applies to any substance.
Then you can apply the following rule of three: if 6.023×10²³ molecules are contained in 1 mole of HCl, then 1.25×10²³ molecules are contained in how many moles of HCl?
amount of moles of HCl= (1.25×10²³ molecules × 1 mole)÷ 6.023×10²³ atoms
amount of moles of HCl= 0.2075 moles
Then, 0.2075 moles of HCl react.
Reaction stoichiometryBy reaction stoichiometry (that is, the relationship between the amount of reagents and products in a chemical reaction), the following amounts of moles of each compound participate in the reaction:
HCl: 2 moles Ba: 1 mole BaCl₂: 1 mole H₂: 1 moleMass of barium chloride producedThen you can apply the following rule of three: if by stoichiometry 2 moles of HCl produce 1 mole of BaCl₂, 0.2075 moles of HCl will produce how many moles of BaCl₂?
[tex]amount of moles of BaCl_{2} =\frac{0.2075 moles of HCl x 1 mole of BaCl_{2} }{ 2moles of HCl}[/tex]
amount of moles of BaCl₂= 0.10375 moles
Being the molar mass of BaCl₂ 208.24 g/mole, then the mass of barium chloride produced is calculated as:
[tex]0.10375 molesx\frac{208.24 grams}{1 mole} =21.6 grams[/tex]
Finally, the mass of barium chloride produced is 21.6 grams.

NH4NO3 Right arrow. N2O 2H2O A chemist who is performing this reaction starts with 160. 1 g of NH4NO3. The molar mass of NH4NO3 is 80. 03 g/mol; the molar mass of water (H2O) is 18. 01 g/mol. What mass, in grams, of H2O is produced? 9. 01 18. 01 36. 03 72. 6.
The mass of water, H₂O produced from the reaction is 72.06 g
We'll begin by calculating the mass of NH₄NO₃ that reacted and the mass of H₂O produced from the balanced equation.
NH₄NO₃ —> N₂O + 2H₂O
Molar mass of NH₄NO₃ = 80.03 g/mol
Mass of NH₄NO₃ from the balanced equation = 1 × 80.03 = 80.03 g
Molar mass of H₂O = 18.01 g/mol
Mass of H₂O from the balanced equation = 2 × 18.01 = 36.02 g
From the balanced equation above,
80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O
Finally, we shall determine the mass of H₂O produced by the reaction of 160.1 g of NH₄NO₃.
From the balanced equation above,
80.03 g of NH₄NO₃ reacted to produce 36.02 g of H₂O.
Therefore,
160.1 g of NH₄NO₃ will react to produce = (160.1 × 36.02) / 80.03 = 72.06 g of H₂O.
Thus, the mass of water, H₂O produced from the reaction is 72.06 g

Which of the following compounds contains the largest number of atoms? *
O A. 1.00 mole of NH3
O B. 1.00 mole of H2SO4
о
C. 1.00 mole of HBr
A 1.00 mole of Sulfuric acid (H₂SO₄) contains the largest number of atoms (7 atoms/molecule). Option B is correct.
To determine which of the given compounds contains the largest number of atoms in 1.00 mole, we need to consider the number of atoms in each compound.
1.00 mole of NH₃ contains:
1 mole of N atoms (1 atom/molecule)
3 moles of H atoms (3 atoms/molecule)
Total atoms = 1 + 3 = 4 atoms/molecule
1.00 mole of H₂SO₄ contains:
2 moles of H atoms (2 atoms/molecule)
1 mole of S atoms (1 atom/molecule)
4 moles of O atoms (4 atoms/molecule)
Total atoms = 2 + 1 + 4 = 7 atoms/molecule
1.00 mole of HBr contains:
1 mole of H atoms (1 atom/molecule)
1 mole of Br atoms (1 atom/molecule)
Total atoms = 1 + 1 = 2 atoms/molecule
Therefore, 1.00 mole of H₂SO₄, contains the largest number of atoms.
Hence, B. is the correct option.

Advantages and disadvantages of titration?
Answer:
What are the advantages of titration?
Titrimetric analysis commonly referred to as volumetric analysis offers distinct advantages over cumbersome gravimetric methods:
Speed of analysis.
Instantaneous completion of reactions.
Greater accuracy due to minimization of material loss involved in decanting, filtration, precipitation or similar operations.
Explanation:
Disadvantages
It is a destructive method often using up relatively large quantities of the substance being analysed.
It requires reactions to occur in a liquid phase, often the chemistry of interest will make this inappropriate.
It can produce significant amounts of chemical waste which has to be disposed of.
It has limited accuracy.
