The answer is B,This is an example of convection, where fluid will circulate.This is because when part of air is warmed up, they expand and become less dense then rise,Therefore, the colder air contracts and become denser and sinks, in order to take in the place of the warm air. This phrase circulates and therefore the it can transfer heat a lot more faster.
Answer:
607 ppm
Explanation:
In this case we can start with the <u>ppm formula</u>:
If we have a solution of <u>0.0320 M</u>, we can say that in 1 L we have 0.032 mol of 
, because the molarity formula is:
In other words:
If we use the <u>atomic mass</u> of 
(19 g/mol) we can convert from mol to g:
Now we can <u>convert from g to mg</u> (1 g= 1000 mg), so:
Finally we can <u>divide by 1 L</u> to find the ppm:
<u>We will have a concentration of 607 ppm.</u>
I hope it helps!
<span> Chemical properties depend on electron configuration. By either gaining or losing electrons, an atom changes its electron configuration and therefore its chemical properties also change. 9.</span>
