True:
They are Nobel gassed! They are un-reactive because there outer shell (valence) is completely full. This means they do not want to lose or gain on electron so they do not react.
It would be fatal for all.The ones on the side of sun would get everything but the ones farer than the sun wouldn't survive.There would be day forever on one side and night forever on other.
The true statement should be B
the electron configuration for Phosphorous is 1s2 2s2 2p6 3s2 3p3
the diagram for 3p3 should be ^_ ^_ ^_ because you want to fill to put an electron in each slot before you double up
Answer:
You see the concentration decreased ten fold, from 1 M to 0.1 M.
You can simply increase the volume by ten times.
For example
If you have 250 mL of 1 molar HCl, you can add distilled water upto 2500 mL. Now the concentration is 0.1 molar.
If you want to use the serial dilution method, you can use the C1V1=C2V2 equation.
C1 = starting concentration.
C2 = final concentration.
V is for volume.
So let's say you have 500 mL of 1 M HCl and you only want 50 mL of 0.1 M HCl.
1 M x V1 = 0.1 M x 50 mL
V1 = 5 mL
So you take 5 mL of the original (stock) solution and dilute it up to 50 mL. Then you have 50 mL of 0.1 M HCl.

Answer:
the activation energy would be 200 kJ since we are looking an endothermic reaction.
