Answer:
Option B. 4 moles of the gaseous product
Explanation:
Data obtained from the question include:
Initial volume (V1) = V
Initial number of mole (n1) = 2 moles
Final volume (V2) = 2V
Final number of mole (n2) =..?
Applying the Avogadro's law equation, we can obtain the number of mole of the gaseous product as follow:
V1/n1 = V2/n2
V/2 = 2V/n2
Cross multiply
V x n2 = 2 x 2V
Divide both side by V
n2 = (2 x 2V)/V
n2 = 2 x 2
n2 = 4 moles
Therefore, 4 moles of the gaseous product were produced.

Give 3 Examples of where potential energy was converted to knlinetic energy:
Curtain
A ball before moving
An apple from the tree then falling down
When the Curtains are still, we call the that potential energy. If you move the curtains around, that is kinetic energy
The ball is still, that is potential energy. Then the ball is moving, the is kinetic energy
There is a apple ganging from a tree, that is potential energy. That apple is fall, this is kinetic energy
Hope this helps
Don't type or write in the answer, I'm not sure what from the lab means. These are a few potential into kinetic energy I could have think of!
To find average atomic mass you multiply the mass of each isotope by its percentage, and then add the values up.
35 * 0.90 + 37 * 0.08 + 38 * 0.02 = 35.22
Average atomic mass closest to 35.22 amu.
