Answer: B) The fireworks give off heat
Answer:
There will 3.95 grams of Na2 and H2O that should be added to form a concentric required solution.
Characteristic properties are used because the sample size and the shape of the substance does not matter.
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
