The pH of the substance is 3.3 which is acidic.
<h3>What is pH?</h3>
The pH of a substance or solution is referred to the degree of acidity or alkalinity of that substance. It is measured on a scale of 0 -14.
Given the concentration of hydrogen ions as 5. 0 × 10–4 moles per liter,we use the formulae
ph = –log[h+]
plugging in thge value of h+ as 5. 0 × 10–4 moles per liter we have:
pH = –log{5. 0 × 10–4 ]
pH=3.3

Explanation: Hope this helped! :)
Answer: (x+3)/2
Explanation:
Tiffany's age is x, and Damon is 3 years older, so we can represent his age as x+3. Mitchel's age is half of Damon's age, so we can represent his age as (x+3)/2.
Yes you can just add then subtract then get your decimal put it in the hole and you get your answer hope this helps!!
