Answer:
pH = -log(concentration of hydro.gen ion)
1. When con. of H ion is 1*10-4 mol/L
pH = -log(1*10-4) = -(-4) = 4
2. A solution with a pH of 1*10-12mol/L
pH = -log (1*10-12) = -(-12) = 12
The pH is 12 and the solution is basic or alkaline
3.A solution with a pH of 6 has the concentration of
pH = -log (H+)
(H+) = arc log -pH
(H+) = 1*10-6
Explanation:
Answer:
Appearing disoriented, such as swimming upside down.
Leaving food uneaten.
White spots on fins or body.
Discolored gills.
Explanation:
Gold Fish are unable to regulate their body temperature, so they are influenced by the temperature around them. If the water is warm, gold fish metabolism accelerates, feeding and respiration increases, and there is a general increase in movement. If the water is cooler, fish become lethargic and tend to be inactive.
C.) Ionic bond is formed between that...
<h2>Answer:</h2>
Moles of a gas = 0.500
Volume = 2.50 L
Pressure = 13. atm
Temperature = ?
Solution:
Formula:
PV = n RT
Putting the values in formula:
T = PV/nR = 13 * 2.5 / 0.5 * 0.082057
= 32.5/0.041 = 792.68 K
T = 792.68 K
