Answer: 0.862 L
Explanation:
First off, I'd like to say that I have not done many problems like this, so this could very well be wrong.
So lets do dimensional analysis:
This gives us 10 L / (0.2 * 58) when we cross out units.
Divide and we get 0.862 L
In the reactants Sb has oxidatin number 0 (because it is in its elemental form)
In the products Sb has oxidaton number +3.
Then Sb lost electrons which means it oxidized.
Here's how you would solve it. The process should be the same for the others.
Most of the light passes through glass but none of the light passes through metal.
Answer:
V₂ = 28 mL
Explanation:
Given data:
Initial temperature = 303 K
Initial volume = 30.0 mL
Final temperature = 283 K
Final volume = ?
Solution:
The given problem will be solve through the Charles Law.
According to this law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
V₂ = V₁T₂/T₁
V₂ = 30.0 mL × 283 K /303 K
V₂ = 8490 mL.K / 303 K
V₂ = 28 mL
