Answer:
pH = 4
Explanation:
Step 1: Given data
Concentration of H⁺ ions in the solution ([H⁺]): 10⁻⁴ M
Step 2: Calculate the pH of the solution
We will use the definition of pH.
pH = -log [H⁺]
pH = -log 10⁻⁴ M
pH = 4
The pH of the solution is 4. Considering the pH scale, given the pH is lower than 7, the solution is acidic.
Answer:
(2) never to be so irresponsible again
Explanation: hope this help!
Climax (the most exciting or plot changing event)
As atomic number increases atomic radii also increase down group 1. ionisation energy down group 1 will also decrease because as atomic radii gets bigger there is less electrostatic force between nuclei and electrons so less energy needed to remove valence electron.
