Thermal energy is the energy that is associated with the random motion of atoms and molecules in a sample of air. The correct option among all the options that are given in the question is option "4".<span>In
reality it is the Kinetic energy that is making the atoms are moved by the
kinetic or thermal energy. The kinetic energy generated by the individual atoms
within the air is moving in their equilibrium position and it can also be
considered as a great example of disordered energy.</span>
There are many examples of chemical equilibrium all around you. One example is a bottle of fizzy cooldrink. In the bottle there is carbon dioxide (CO2) dissolved in the liquid. There is also CO2 gas in the space between the liquid and the cap
Answer:
Compound
Explanation:
We want to know if it's a compound or a mixture.
An example of a mixture is salt water: you can heat it hot enough to boil off the water, leaving only the salt. This is a physical change, which is how you know it's a mixture.
Something like gold is a compound: if you heat it, or hit it, you'll still only have gold. You can only break it down by chemical means, which is how you know it's a compound.
Answer:
i also had this question:P
Explanation:
The simple formula is C = n/V
n = mols
C = Concentration or Molarity
V = Volume in Liters.
n = 2
V = 4
C = 2 / 4
C = 0.5 mol/Litre
