Answer:
Moving from left to right across a period, the atomic radius decreases. The nucleus of the atom gains protons moving from left to right, increasing the positive charge of the nucleus and increasing the attractive force of the nucleus upon the electrons.
Pros it will sustain our daily needs and will never run out
I think it’s no, no, yes, yes. But I could very well be wrong
Answer:<span>0.40 atm
How did we get 0.40?
Use the formula of Dalton's Law of partial pressure. </span>
Work it out by substituting the given values.
Given:
Total gas exerted by nitrogen- 80%
Total pressure- 2.0 atm
pressure of oxygen-?
P denotes total pressure exerted by nitrogen and n denotes total pressure of the mixture.
Poxygen = P/n
= 0.8 /2.0
= 0.4
(80 % is changed into decimal number, 0.8)
