Hi!
The correct answer would be chemical energy.
Energy is classified into two basic categories:
Kinetic Energy
Potential Energy
Kinetic energy is possessed by objects or particles in motion, like waves or molecules as a system. Kinetic energy further includes sound energy (along with others not in listed in the question)
Potential energy is the energy that is reserved/stored or possessed by an object in a particular position. Potential energy further includes gravitational and chemical energy (along with others not in the question)
The energy between bonds is a form of potential energy, as energy is stored in the bonds. The energy stored in the bond is associated with the position of the atoms in relation to one another and the structure of the molecule.
Hope this helps!
Hello!
It's actually easy to add a half drop of NaOH from the buret, you'll only need to be careful.
For doing that, you'll need to first open the flow of the buret until a little drop appears, and close it before it falls to the titrating flask. Then, you'll need to rinse the tip of the buret with deionized water to make the half drop fall into the titrating flask.
Don't worry about diluting your sample with the deionized water, since you are titrating the total moles of your analyte in the solution, and those won't change with concentration.
Have a nice day!
Answer: Option (4) is the correct answer.
Explanation:
It is known that equilibrium constant is represented as follows for any general reaction.
K =
As equilibrium constant is directly proportional to the concentration of products so more is the value of equilibrium constant more will be the number of products formed.
As a result, more is the time taken by the reaction to reach towards equilibrium. Whereas smaller is the value of equilibrium constant more rapidly it will reach towards the equilibrium.
Thus, we can conclude that cases where K is a very small number will require the LEAST time to arrive at equilibrium.
Mass is weight valume is liquid
The common substance among the product(s) of the first equation and among the reactant(s) in the second equation is H2O(g). We can eliminate that as an intermediate. The overall chemical equation will thus be:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(l),
which is the first answer choice.
In essence, all you’re doing here is swapping water vapor for liquid water.
