Answer:
x>4
Step-by-step explanation:
Do 5x>24-4 subtract... the u have 5x>20 so you divide both sides by 5 and u get 4
3x-2=3
3x=3+2
3x=5
x=5/3
Answer : According to the information provided in the question, the value of 'x' is 5/3
Answer:
Option A
..............................................................
<u>A substance is tested and has a </u><u>Ph of 7.0</u><u>. It would be </u><u> a weak acid. </u>
<u>The correct option is </u><u>(c) a weak acid .</u>
<u></u>
What is the nature of substance if the pH is less than 7?
- Acidity is defined as pH below 7. More than 7 pH is considered basic.
- Each whole pH number below 7 is ten times more acidic than the next higher value since the pH scale is logarithmic.
- For instance, pH 4 is 100 times (10 times 10) more acidic than pH 6, while pH 5 is ten times (10 times) more acidic than pH 4.
What is pH?
- The pH scale determines how acidic or basic water is.
- The range is 0 to 14, with 7 representing neutrality.
- Acidity is indicated by pH values below 7, whereas baseness is shown by pH values above 7.
- In reality, pH is a measurement of the proportion of free hydrogen and hydroxyl ions in water.
