How much more [H+] does lemon juice (pH 2) have compared with pure water (pH 7)? Remember that each pH unit represents a 10 fold
Tresset [2298]

Answer:

10^5 \\or\\100,000

Explanation:

The pH formula is given by

pH = -[log H+]\\

It's also stated that each pH unit indicates a tenfold change in hydrogen ion concentration.

For lemon juice with a pH of 2, the hydrogen ion concentration is

10^-2\\= \frac{1}{100}

While for pure water, which has a pH of 7, the concentration is

10^ -7\\= \frac{1}{10000000}

Thus, the concentration of H+ ions in lemon juice is 10^5 times greater than in pure water.

What differences, if any, are there between the function of the normal brainstem and that of the split-brain brainstem?
garik1379 [2080]
The term split brain refers to the condition when the corpus callosum, which connects the two hemispheres of the brain, is partially or completely severed. Studies indicate that dividing the brain in this way impacts the individual's behavior. Several differences have been found between those with an intact brain and those with a split brain. For example, people who have experienced partial brain removal often show impaired coordination between their left and right body sides. Additionally, they display restricted visual awareness and difficulties with language.
