Answer:
No
Explanation:
It is not correct to say that an object with the largest volume has the largest mass.
Mass and volume are not directly related. In fact, the relationship between them can be direct or inverse.
Mass is the amount of matter in a substance. Volume is the space a body occupies.
- A balloon and a stone for example is a typical one.
- A balloon has more volume but far lesser mass compared to a stone.
- A stone, gravel sized has low volume but more massive than a balloon.
Therefore, it is wrong to say a balloon has more mass because it has more volume.
Answer:
D
Explanation: Decreasing the temperature of the system would lower the reaction rate.
Answer:
pH = 8.34
Explanation:
The equilbriums of the amphoteric HCO₃⁻ (Ion of NaHCO₃) are:
H₂CO₃ ⇄ <em>HCO₃⁻</em> + H⁺ Ka1 <em>-Here, HCO₃⁻ is acting as a base-</em>
<em>HCO₃⁻</em>⇄ CO₃²⁻ + H⁺ Ka2 <em>-Here, is acting as an acid-</em>
Where Ka1 = 4.3x10⁻⁷ and Ka2 = 4.8x10⁻¹¹. As pKa = -log Ka:
pKa1 = 6.37; pKa2 = 10.32
As the pH of amphoteric salts is:
pH = (pKa1 + pKa2) / 2
<h2>pH = 8.34</h2>
Answer:
1 and 2
Explanation:
when we r adding chlorine to water
the water is clean
The natural environment or natural world encompasses all living and non-living things occurring naturally, meaning in this case not artificial.
