Answer:
It will not dissolve. More crystals will separate from the solution.
Step-by-step explanation:
If you add a crystal of ammonium nitrate to a supersaturated solution of the solute, it will not dissolve.
Instead, it will act as a "seed" on which more ammonium nitrate crystals will form.
They will separate from the solution as long, colourless, needle-like crystals until the solution is no longer supersaturated.
Using the equation, pH = − log [H+] , we can solve for [H+] as,
− pH = log [H+] ,
[H+] = 10−pH.
Exponentiate both sides with base 10 to "undo" the common logarithm. The hydrogen ion concentration of blood with pH 7.4 is,
[H+] = 10−7.4 ≈ 0.0000040 = 4.0 × 10−8 M.
Answer:
yes
Explanation:
Although plants use photosynthesis to produce glucose, they use cellular respiration to release energy from the glucose.
