Answer: I think this is it. I really havnt done science/Chemistry in a while.
2KNO3
Explanation:
Answer: The answer is D.
Explanation:
As the air rushes toward the center, it winds up moving in a curved path thanks to the Coriolis effect. This creates a circular spinning pattern as air travels from areas of high pressure to low pressure. That's why hurricanes originating in the northern hemisphere rotate counterclockwise.
Hope this helps!
The answer is D. The teacher describes the plant by saying it has leaves, stems, roots, and fruit. stems are vascular tissue so it can't be C, B, or A.
The question above can be answered by using the volume balance concept. Two equations can be established by total volume balance and the component (acid) volume balance.
If we let x be the volume of the 12% acid solution, the volume of the 20% acid solution will have to be 100 - x.
x + (100 - x) = 100
Then, the acid mass balance will give us the equation,
(x)(0.12) + (100 - x)(0.20) = (100)(0.18)
Simplifying,
0.12x + 20 - 0.20x = 18
-0.08x = 20 - 18
-0.08x = 2
The value of x from the equation is 25.
<em>Hence, the volume of the 12% acid solution is 20 galloons and that of the 20% acid solution is 75 galloons. </em>
