Their average speed during the trip is 53 km/ hr approximately
Explanation: The family traveled 80 km/hr for an hour and then trabeled 40 km/ hr for 2 hours. So they traveled 80 km in one hour then 80 km in the next 2 hours. Total they traveled 160 km in 3 hours.
Average speed = distance traveled/ taken time
= 160/3 = 53.33
Answer:
Erosion
Explanation:
Because that's what it looks like
Answer:
c. CH₃COO⁻
Explanation:
The task is not very clear but I think this is the original question.
<em>Identify the conjugate base of CH₃COOH in the reaction:
</em>
<em>CH₃COOH + HSO₄⁻ ⇄ H₂SO₄ + CH₃COO⁻
</em>
<em>a. HSO₄⁻
</em>
<em>b. SO₄²⁻
</em>
<em>c. CH₃COO⁻</em>
<em>d. H₂SO₄</em>
<em>e. OH⁻</em>
Let's consider the following reaction
CH₃COOH + HSO₄⁻ ⇄ H₂SO₄ + CH₃COO⁻
According to the Bronsted-Lowry acid-base theory, an acid is a species that donates H⁺ and a base is a species that accepts H⁺.
CH₃COOH is an acid because it donates H⁺ to HSO₄⁻, whereas CH₃COO⁻ is its conjugate base, because it accepts H⁺ from H₂SO₄ to form CH₃COOH.
Another acid-base pair is H₂SO₄/HSO₄⁻
