Answer:
a) After helping our partner, we should immediately report the incident to the lab manager or any person in charge of the emergencies occurring in the lab.
b) We should have a copy of the Material Safety Data Sheet to give to the responders. This is because the responder can identify what materials were being used by the person ans what other security measures need to be taken.
I think it’s true... hope this helps
Answer : The symbol of the element is Selenium (Se).
Explanation :
Electronic configuration is distribution of electrons in an atom in atomic orbitals.
The electronic configuration of [Kr] =
Total number of electrons in [Kr] = 36
Due to -2 charge, 2 electrons are withdrawn from the electronic configuration of [Kr].
Now the total number of electrons left = 36 - 2 = 34
And the Selenium[Se] is the element which has 34 number of electrons.
Electronic configuration of [Se] =
The concept of Standard electrode potential can be used to accomplish this.
<h3><u>
Standard Reduction Potential</u></h3>
The standard reduction potential belongs to the group of potentials known as standard electrodes or standard cells. The difference in voltage between the cathode and anode is known as the standard cell potential. . All of the standard potentials are determined using 1 M solutions, 1 atm, and 298 K.
The probability of reducing a species is known as its standard reduction potential. It is expressed as a reduction half reaction in writing. Below is an illustration where "A" stands for a generic element and "C" represents the charge.
<u>Standard Reduction Potential:</u>
A⁽⁺+Ce⁻→A
For example, copper's Standard Reduction Potential of Eo=+0.340V) is for this reaction:
Cu²⁺+2e⁻→ Cu
The standard reduction potential and the standard oxidation potential are quite similar. It is the propensity of a species to undergo oxidation under normal circumstances. Additionally, it is written as a half reaction.
