The correct answer is B. He doesn’t wear goggles because he is using household chemicals.

Explanation:

Carrying out experiments especially those that imply substances such as chemicals implies following practices to guarantee safety. Because of this, in the lab you should use special clothes this includes goggles and gloves; you should clean and decontaminate your station; avoid eating, drinking or smoking and always ask your teacher for any step or procedure. This implies, the inappropriate action is "He doesn’t wear goggles because he is using household chemicals", because protection should be used all the time as even substance we use every day can be dangerous if you are closely exposed to them or if they are mixed with others.

If the solubility of a gas in water at 25°C is 22.25 mg/L at 2.5 atm of pressure, what is its solubility (in mg/L) at 25°C
tamaranim1 [39]

Answer:

8.9 mg/l

Explanation: Temp doesnt matter so throw that out automatically then your equation is;

S1/P1=S2/P2

We are looking for S2 and that equation is;

S2=S1*P2/P1 and that is S2=22.25*1/2.5

A little bit of simple math and you get your answer: 8.9 mg/l
