Answer:
1.) [H⁺] = 2.69 x 10⁻⁹
2.) [H⁺] = 6.61 x 10⁻⁶
3.) [H⁺] = 5.01 x 10⁻²
Explanation:
The [H⁺] in a solution can be found using the following equation:
[H⁺] = 10^(-pH)
Therefore, you can plug the given pH into the equation and solve for the hydrogen ion concentration ([H⁺]).
1.) pH 8.57
[H⁺] = 10^(-pH)
[H⁺] = 10^(-8.57)
[H⁺] = 2.69 x 10⁻⁹
2.) pH 5.18
[H⁺] = 10^(-pH)
[H⁺] = 10^(-5.18)
[H⁺] = 6.61 x 10⁻⁶
3.) pH 1.30
[H⁺] = 10^(-pH)
[H⁺] = 10^(-1.30)
[H⁺] = 5.01 x 10⁻²
Energy can make matter do all of the above, so D
The brain is protected by the bones of the skull and by a covering of three thin membranes called meninges. The brain is also cushioned and protected by cerebrospinal fluid. This watery fluid is produced by special cells in the four hollow spaces in the brain, called ventricles.
For Single Element Ions (e.g. K+ , Mg2+, P3-) To name positive (+) ions write the name as from the Periodic Table and add the word 'ion' afterwards. To name negative (-) ions write the name from the Periodic Table but replace the ending with 'ide'. Put the word 'ion' after the name.
