Answer:
D. Sr < Ca < Be
Step-by-step explanation:
<em>Ionization energ</em>y decreases from top to bottom within a Group, because the valence electrons are further from the nucleus and therefore easier to remove.
Thus, <em>Sr has the lowest</em> ionization energy and <em>Be the highes</em>t.
The correct order is Sr < Ca < Be.
I am not 100% this is right but
Hope this helps :))
Answer:
Condensation is the process of water vapor condensing into liquid water.
Explanation:
"Water condenses on a can of cold soda. Water vapor in the air reaches its dew point as it cools in the air around the can, forming liquid drops of water. Condensation is the process where water vapor becomes liquid. It is the reverse of evaporation, where liquid water becomes a vapor." -National Geographic"
Answer:
616,0 ng is the right answer.
Explanation:
You should know that 1 mole = 1 .10^9 nanomoles
Get the rule of three.
1 .10^9 nanomoles ...................... 56.0 gr
11 nanomoles .....................
(11 x 56) / 1 .10^9 nanomoles = 6.16 x 10^-7 gr
Let's convert
6.16 x 10^-7 gr x 1 .10^9 = 616 ngr
