True, if you would like an example look at Indian arrow heads or early architecture all use rocks.
Answer:
[H⁺] = 3.16 × 10⁻⁵ mol/L
Explanation:
Given data:
pH of solution = 4.5
Hydrogen ion concentration = ?
Solution;
pH = -log [H⁺]
we will rearrange this formula:
[H⁺] = 10∧-pH
[H⁺] = 10⁻⁴°⁵
[H⁺] = 3.16 × 10⁻⁵ mol/L
B. Share Electrons.
Hope this helps.
Metal? Copper? I don’t know I just have to answer to get my question answered, have a good day!
