Answer:
There is one mole in 6.02*10^23 particles of anything ( also CO2)
Thomas discovered cathode rays when he was working with electrons. He was performing experiments with electrons when one of them became electrically charged and a beam of light came from it, this creating a cathode ray.
Answer:
B) exothermic.
Explanation:
Hello!
In this case, we need to keep in mind that exothermic reactions release heat, so they increase the temperature as the final energy is less than the initial energy; in contrast, endothermic reactions absorb heat, so they decrease the temperature as the final energy is greater than the initial energy.
In such a way, when a dissolution process shows off a negative enthalpy of dissolution, we infer it is an exothermic process due to the aforementioned; therefore, the answer is:
B) exothermic

Photosynthesis has a huge role in the carbon cycle and in the Calvin cycle because photosynthesis is a way of transforming carbon dioxide into glucose, sugars, and oxygen.
Hope this helped :)
Answer is: solution B is saturated and solution A is unsaturated.
Saturated solution contains the maximum concentration of a solute dissolved in the solvent (usually water) and if extra solute is added to saturated solution, that solute will not dissolve.
Unsaturated solution means that more of a substance can be dissolved (in this example salt).
