Lemon juice has a ph of about 2.0, compared to a ph of about 1.0 for stomach acid. therefore, the concentration of h+ in stomach acid is than that of lemon juice.

The concentration of h+ in stomach acid is  times more than that of lemon juice.

Explanation:

Basically, pH is a value that rates how acidic or alkaline a solution is on a scale from 0–14. A pH of 7 is considered neutral. Any pH value below 7 is considered acidic and any pH value over 7 is considered alkaline. Acidic solutions have a lower pH, while basic solutions have a higher pH.

On the pH scale, the difference between adjacent numbers represents a tenfold difference in acidity. For instance, a pH of 4 is 10 times more acidic than a pH of 5 and 100 times more acidic than a pH of 6.

Since the lemon juice has a pH of about 2.0 compared to stomach acid with a pH of about 1.0 It means that the the stomach acid is 10 times more acidic than the lemon juice.

pH = -log10[H+]

[H+] = 10^-pH

In Lemon juice;

[H+] = 10^-pH = 10^-2 = 0.01

In stomach acid;

[H+] = 10^-pH = 10^-1 = 0.1

0.1 is 10 times more than 0.01.

because u need two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei to form isotopes.

so since they all have the same shape? i mean maybe because m& m and reeses are both chocolates

you gotta add the following molecules so we can give u an answer
