Explanation:
4HCl + O₂ ⇌ 2Cl₂ + 2H₂O
E/mol·L⁻¹: 0.80 0.20 3.0 3.0
![K_{\text{eq}} = \dfrac{\text{[Cl$_{2}$]$^{2}$[H$_{2}$O]$^{2}$}}{\text{[HCl]$^{4}$[O$_{2}$]}} = \dfrac{3.0^{2}\times3.0^{2}}{0.80^{4}\times 0.20} = \mathbf{990}\\\\\text{The $K_{\text{eq}}$ value is $\large \boxed{\mathbf{990}}$}](https://tex.z-dn.net/?f=K_%7B%5Ctext%7Beq%7D%7D%20%3D%20%5Cdfrac%7B%5Ctext%7B%5BCl%24_%7B2%7D%24%5D%24%5E%7B2%7D%24%5BH%24_%7B2%7D%24O%5D%24%5E%7B2%7D%24%7D%7D%7B%5Ctext%7B%5BHCl%5D%24%5E%7B4%7D%24%5BO%24_%7B2%7D%24%5D%7D%7D%20%3D%20%5Cdfrac%7B3.0%5E%7B2%7D%5Ctimes3.0%5E%7B2%7D%7D%7B0.80%5E%7B4%7D%5Ctimes%200.20%7D%20%3D%20%5Cmathbf%7B990%7D%5C%5C%5C%5C%5Ctext%7BThe%20%24K_%7B%5Ctext%7Beq%7D%7D%24%20value%20is%20%24%5Clarge%20%5Cboxed%7B%5Cmathbf%7B990%7D%7D%24%7D)
This type of chemical bond is called an ionic bond because the bond formed between two ions of opposite charge.
The object that I think has potential energy within the images posted is the skateboard at the top of the ramp.
<h3>Why do i think this one has potential energy?</h3>
Potential energy is a type of mechanical energy in which there is a type of stored energy that can be transformed into another type of energy. This energy is given by the <u>location of the body</u> with respect to a force field.
I selected the image of the skateboard at the top of the ramp since going up there uses kinetic energy and when it is on top of the ramp, waiting to go down, this kinetic energy is stored in potential energy that is ready to be released. The higher the height at which it is launched, <u>the more its potential energy will be</u>.
Therefore, we can confirm that the object that I think has potential energy within the images posted is the skateboard at the top of the ramp.

Answer:
The light bulb converts electrical energy into light and <u>heat energy</u>
Answer:
3.6 times 10^4
Explanation:
Scientific notation is between 1-9. So, we move 36000 to 4 decimal places. SO it would be 3.6 times 10^4. Scientific Notation always has the base of 10 . Enjoy :)
