that's the answer comparison with standard mass units
The temperature dropped because B. energy was absorbed during the chemical reaction.
If energy was released, the temperature would rise. If there was no energy input, the temperature would stay the same. Since temperature dropped, it means that energy was absorbed.
Answer:
alot
Explanation:
because salt contains stuff
Let A be the 15% canned juice and B be 5% juice
Va + Vb = 10
Vb = 10 - Va
Concentration of final solution = 12% juice
10 x 0.12 = Va x 0.15 + Vb x 0.05
Substituting Vb from the first equation:
1.2 = 0.15Va + 0.5 - 0.05Va
Va = 7 liters
Vb = 3 liters
7 liters of the 15% juice and 3 liters of the 5% juice.
