Answer:
The explanation to your question is below.
Explanation:
In thermochemistry, reactions are classify in two groups.
- Endothermic reactions: are reactions that need energy (heat) from the surroundings to happen. If they are not heated, the products will not form.
Example:
2 H₂O + energy ⇒ 2H₂ + O₂
-Exothermic reactions: are reactions that release energy to the surroundings. They happen spontaneously.
Example:
CH₄ + 2O₂ ⇒ CO₂ + 2H₂O + energy (heat)
Answer:
If any atom has more electrons than one energy level can hold, then automatically the electron is accommodated in the next energy level (shell). The remaining extra electrons starts to fill the next energy level. This produces the valency of that particular atom.
Explanation:
The answer is natural gasses
For this problem, we use the equation derived from Beer's Law as written below:
A = ∈LC,
where
A is the absorbance
∈ is the molar absorptivity
L is the path length of the cuvette
C is the concentration of the sample solution placed in the cuvette
To determine C, we have to know the rest of the parameters. Generally, the equation for C would be:
C = A/∈L = A/∈(1 cm)
C = A/∈
If you know the absorbance and the molar absorptivity in mol/L·cm, you can determine the value of C.
If you are asking for the formula, here it is. \
