Answer:
So, electrolysis of water produces 2 volumes of hydrogen gas and 1 volume of oxygen gas because the ratio of hydrogen and oxygen elements in water is 2:1 by volume. Therefore, the amount of gases collected in two test tubes is not equal.
i hope this helped, have a great day
I see that you already have an answer so I’m just typing for points
Answer:
B
Explanation:
Coal is a non-renewable resource, so the supply can't produce faster than we can mine it.
<span>0.72 mL of solution will have 180 mg of amoxicillin.
For this problem, you need to calculate the equivalent ratio of volume as to the ratio of amoxicillin. So
180/500 = X/2.0
Multiply both sides by 2
2 * 180/500 = X
360/500 = X
18/25 = X
0.72 = X
So you need 0.72 mL of solution to get 180 mg of the drug.</span>
