Answer:
Energy is released or absorbed in a chemical change
Explanation:
In a chemical change a new substance is formed from it.
pH: 5.4E-3
pOH: 13.9946
[H+]: 0.987643022777
[OH-]: 1.01251158256E-14 acid
The answer is A.
Remember that diffusion is the spontaneous process of solutes moving from areas of higher concentration to areas of lower concentration (spontaneous just means the process doesn't require an input of energy to occur).
Answer:
7
Explanation:
pH electrodes will NOT give accurate pH values in distilled or deionized water because distilled and deionized water do not have enough ions present for the electrode to function properly. ... It is important to keep mind that water (distilled, deionized, or tap) is NOT “pure” (i.e., pH equal to 7).
Yes, it can happen.
If all the lower energy orbits are already filled with electrons, then it cannot happen since the lower orbitals will already be full, hence another electron will have to move.
However, if the lower energy orbits are not full (for instance if one excited electron goes back to its normal state), then it can happen.
