Answer:
As potassium is larger than sodium, potassium's valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium's valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive.

An orbital is the most probable location of an electron. This is because you can't pinpoint the exact location of an electron because as soon as you do it will have moved again, so orbitals are used to find the probability of where a certain electron is.
PbCl2--->Pb2+ + 2Cl-
The mass of PbCl2 is =mass of the beaker+Pbcl2 minus mass of the beaker
that is 62.19-57.77g= 4.42grams
moles of PbCl2= 4.42g/278g/m0l = 0.0159moles
concentration of (Pb2+)
since mole ratio of PbCl2 to Pb2+ is 1:1 therefore the moles of Pb2+ is also 0.0159moles
concentration =0.0159/100 x1000=0.159M
concentration of CI- is two time that of Pb2+ from the equation above therefore concentration of Cl- = 0.159 x2 =0.318M
Answer:
Define the Problem
Background Research
Write a Hypothesis
Carry Out the Experiment
Analyze Data
Draw a Conclusion
Explanation:
First of all, identify the first and last steps before figuring out the middle.
In order, the first and last steps should be
Define the Problem
...
Draw a Conclusion.
Next, you can add your answers in the middle, from beginning to end. That would be,
Define the Problem
Background Research
Write a Hypothesis
Carry Out the Experiment
Analyze Data
Draw a Conclusion
Let me know if this is inaccurate as I am learning everyday. Hope this helped!
