A 1.5 L pocket of air with a temperature of 295 K rises in the atmosphere. What will be the volume of the air pocket of the t temperature decreased to 2 celsius and the pressure is not changed.
Answer:
1.4 L.
Explanation:
Applying Charles law,
V/T = V'/T'....................... Equation 1
Where V = Initial volume, V' = Final volume, T = Initial Temperature in Kelvin, T' = Final Temperature in Kelvin.
Make V' the subject of the equation
V' = (V/T)T'..................... Euqation 2
Given: V = 1.5 L, T = 295 K, T' = 2 °C = (2+273) K = 275 K
Substitute these values into equation 2
V' = (1.5/295)275
V' = 1.398
V' ≈ 1.4 L

Can rotation and revolution occur at the same time? Explain.
Answer:
yes
Explanation:
Revolution is the movement of an object around another object. So, Earth revolves around the Sun, and the Moon revolves around Earth. At the same time, Earth and the Moon are also rotating. Earth's rate of revolution is about 365 days (one year), and its rate of rotation is about 24 hours (one day).
___ SeCl6 + ___ O2 --> ___ SeO2 + ___ Cl2
What is the balanced equation for these reactions?
I give Brainliest! Please no links
Answer:
SeCl₆ + O₂ → SeO₂ + 3Cl₂
Explanation:
Unbalanced:
SeCl₆ + O₂ → SeO₂ + Cl₂
Count the atoms.
On the left side, we have 1 Se atom, 6 Cl atoms, and 2 O atoms.
On the right side, we have 1 Se atom, 2 O atoms, and 2 Cl atoms.
So everything is balanced except for Cl. To balance, we put a 3 coefficient in front of Cl₂.
SeCl₆ + O₂ → SeO₂ + 3Cl₂

Calculate the molarity of a solution prepared by dissolving 6.87 grams of AgNO3 in enough water to make 2.50 liters of solution.
Answer:
The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]
Explanation:
Molar concentration is a measure of the concentration of a solute in a solution.
Molarity (M) or Molar Concentration is the number of moles of solute that are dissolved in a certain volume.
Molarity is determined by dividing the moles of the solute by the volume of the solution:
[tex]Molarity=\frac{number of moles of solute}{volume}[/tex]
Molarity is expressed in units [tex]\frac{moles}{liter}[/tex].
Being 169.87 g / mole the molar mass of AgNO₃, then you can apply the following rule of three: if 169.87 grams are contained in 1 mole, 6.87 grams are contained in how many moles?
[tex]amount of moles=\frac{6.87 grams*1 mole}{169.87 grams}[/tex]
amount of moles= 0.04 moles
Then:
number of moles of solute: 0.04 molesvolume: 2.50 LReplacing:
[tex]Molarity=\frac{0.04 moles}{2.50 L}[/tex]
Solving:
Molarity= 0.016 [tex]\frac{moles}{L}[/tex]
The molarity of the solution is 0.016 [tex]\frac{moles}{L}[/tex]

Describe how temperature changes the average Molecular kinetic energy?
According to Kinetic Molecular Theory, an increase in temperature will increase the average kinetic energy of the molecules. As the particles move faster, they will likely hit the edge of the container more often. If the reaction is kept at constant pressure, they must stay farther apart, and an increase in volume will compensate for the increase in particle collision with the surface of the container.

what are the respective coefficients needed to balance the equation below _N2(g) + _H2(g) --> _NH3(g)
In the balanced equation, the mass of reactant is exactly equal to the mass of product. The respective coefficients needed to balance the equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .
What is balanced equation ?A chemical equation that is balanced has equal amounts of each element's atoms on both sides of the equation and conserves mass.
Because mass cannot be generated or destroyed, according to the rule of conservation of mass, a chemical equation must always be in balance.
The Law of Conservation of Mass is followed by a balanced equation. This is a crucial scientific guiding principle. Finally, a balanced equation enables us to forecast the quantity of reactants and products that will be produced. Sort of crucial if you're attempting to determine how much fuel to supply a spacecraft traveling to Mars
Thus, the balanced equation is N₂(g) + 3H₂(g) ⇒ NH₃(g) .

Answer:
27 g
Explanation:
From the question,
n = Mv...................... Equation 1
Where n = number of mole of Al₂SO₄, M = Molarity of Al₂SO₄, v = Volume of the solution.
Given: M = 0.12 mol/L, v = 1.5 L.
Substitute these values into equation 1
n = 0.12×1.5
n = 0.18 mol
Also,
n = Mass(m)/Molar mass (m')
n = m/m'.
m = n×m'......................... Equation 2
Given: The molar mass of Al₂SO₄ = (27×2)+32+(16×4) = 150 g/mol
Substitute into equation 2
m = 0.18×150
m = 27 g

In at least 4 complete sentences, describe the similarities and differences between Avogadro's Law and Charles' Law.
answer
Avogadro's law states that, at constant temperature and pressure, the volume of a gas is directly proportional to the number of moles present. In other words, equal volumes of gases at the same pressure and temperature contain the same number of molecules - this is true regardless of their physical properties or chemical nature.
