Answer:
The Californian red wine (pH 3.5) has a hydrogen concentration of 0.00032M
The italian white wine (pH 2.9) has a hydrogen concentration of 0.00126 M
Explanation:
<u>Step 1:</u> Data given
Wine 1 has a pH of 3.5
Wine 2 has a pH of 2.9
Wine 2 is more acid so should have more hydrogen ions
<u>Step 2:</u> Calculate hydrogen concentration
pH = -log [H+]
Wine 1: pH = 3.5 = -log[H+]
[H] = 10 ^-3.5 M = 0.00032 M
Wine 2: pH =2.9 = -log[H+]
[H+] = 10^-2.9 = 0.00126 M
The Californian red wine (pH 3.5) has a hydrogen concentration of 0.00032M
The italian white wine (pH 2.9) has a hydrogen concentration of 0.00126 M
The italian white wine has a higher concentration of hydrogen ions, what means it's more acid than the californian red wine.
Answer:
B
Explanation:
When work is done, energy is transferred between systems, or transformed from one type of energy into another type. Energy shares the same units of measure as work.
