There isn't any molecules in plasma, hope this helps
Answer:
The part of the experiment that is set to compare data
Explanation:
The controlled variable is what stays constant throughout an experiment. You use the controlled variable to compare the new data to see what happened during whatever reaction you could say.
Answer:
so i never did this befor so i am sorry hope you get the answer

![\large \boxed{\text{D. 23.34 min}}](https://tex.z-dn.net/?f=%5Clarge%20%5Cboxed%7B%5Ctext%7BD.%2023.34%20min%7D%7D)
Explanation:
1. Find the order of reaction
Use information from the graph to find the order.
If a plot of ln[A] vs time is linear, the reaction is first order and the slope = -k.
2. Find the half-life
![k = \dfrac{\ln2}{ t_{\frac{1}{2}}}\\\\k = \text{-slope} = -(-2.97 \times 10^{-2} \text{ min}^{-1}) =2.97 \times 10^{-2} \text{ min}^{-1} \\ t_{\frac{1}{2}} =\dfrac{\ln 2}{k} = \dfrac{\ln 2}{2.97 \times 10^{-2}\text{ min}^{-1}} =\textbf{23.34 min}\\\\\text{The half-life is $\large \boxed{\textbf{23.34 min}}$}](https://tex.z-dn.net/?f=k%20%3D%20%5Cdfrac%7B%5Cln2%7D%7B%20t_%7B%5Cfrac%7B1%7D%7B2%7D%7D%7D%5C%5C%5C%5Ck%20%3D%20%5Ctext%7B-slope%7D%20%3D%20-%28-2.97%20%5Ctimes%2010%5E%7B-2%7D%20%5Ctext%7B%20min%7D%5E%7B-1%7D%29%20%3D2.97%20%5Ctimes%2010%5E%7B-2%7D%20%5Ctext%7B%20min%7D%5E%7B-1%7D%20%5C%5C%20t_%7B%5Cfrac%7B1%7D%7B2%7D%7D%20%3D%5Cdfrac%7B%5Cln%202%7D%7Bk%7D%20%3D%20%5Cdfrac%7B%5Cln%202%7D%7B2.97%20%5Ctimes%2010%5E%7B-2%7D%5Ctext%7B%20min%7D%5E%7B-1%7D%7D%20%3D%5Ctextbf%7B23.34%20min%7D%5C%5C%5C%5C%5Ctext%7BThe%20half-life%20is%20%24%5Clarge%20%5Cboxed%7B%5Ctextbf%7B23.34%20min%7D%7D%24%7D)
When forming an ion, this sodium atom will lose 1 electron, as it is the easiest way to form a full shell, as opposed to gaining 7 electrons.
