Answer:
The concentration of the sample is 3.564x10⁻³M.
Explanation:
Using Lambert-Beer law, absorbance of a sample is directely proportional to its concentration.
The general graph of the absorbance of the standards with different concentrations is:
Y = 75.9X + 0.0045
R² = 0.9946
<em>Where Y is the absorbance of the sample and X its concentration in mole/L.</em>
If a solution has an absorbance of 0.275:
0.275 = 75.9X + 0.0045
0.2705 = 75.9X
3.564x10⁻³M = X → The concentration of the sample.
Answer:
The molecular geometry of SO3 is trigonal planar.
Explanation:
Look at the Lewis
Answer:
The process of combining the smaller nuclei to make larger one is called fusion.
Fusion occurs on the sun.
Explanation:
Fusion:
It is the process in which smaller nuclei combine to form the larger nuclei.
Fusion process also occur in the sun.
It is known as proton-proton fusion. In this proton-proton fusion, the atoms of hydrogen fused together and form helium-4. This is accomplished through several steps hydrogen atoms combine to form deuterium.
This deuterium atom fused with proton and form helium- 3.
Gamma rays are also produced in this reaction.
This helium-3 combine with another helium-3 and form helium-4 atom and two protons.
