Decreases
Explanation:
The molecules lose potential energy during chemical reactions.
In a chemical reactions, bonds are broken for new ones to be formed. The process of breaking and forming bonds diminishes the potential energy of a bond.
Potential energy is the energy at rest in a body.
In chemicals, potential energy is constituted by the chemical energy stored within the bonds.
When chemical reactions occur, the energy is released often in the form of heat energy. There is always a decrease in potential energy when chemicals reacts together.

Answer the correct answer out of the four is option c spectroscopy
Explanation- The interaction between electromagnetic radiation and matter studied. This study is commonly known as spectroscopy. It can also be named as study of absorption spectra or emission spectra.
The former spectrum is formed when energy is absorbed from Photons or light energy by electrons while the latter spectrum is formed due to a wavelength of light that is released when electrons jump from higher to lower level.
Hey there!
Molar mass of O3 = 47.9982 g/mol
therefore:
1 mole O₃ --------------------- 47.9982 g
moles O₃ ---------------------- 24 g
moles O₃ = 24 x 1 / 47.9982
moles O₃ = 24 / 47.9982
moles O₃ = 0.500 moles
Hope this helps!
<span>The atomic weight of 13C should be pretty close to 13.0. (If you have the exact mass, use it in the problem.) So,
9.00 g / 13.0 g/mol = 0.692 moles
Therefore, the answer should be 0.692 moles are in 9.00 g of 13C.</span>
Answer: {1102.91}
Given: K= °C + 273.15
K = 1,376.06
Since you’re trying to find C (Celsius) you want to get C by itself in the problem. So you subtract 273.15 from that side. Anything you do to one side of the equal sign you have to do to the other side, so also subtract 273.15 from K (1,376.06).
1,376.06 - 273.15 = {1102.91°C}
