The answer is 5.5x10 to the power of 27.
6.02x10 to the power of 23 is how many particles are in one mole.
Therefore, if there are 922 moles then by cross-multiplying I multiplied 6.02x10 to the power of 23 with 922 and that's how I got the answer of 5.5x10 to the power of 27.
Answer: Geotropism allows the plants to correctly orient themselves for growth.
Explanation:
<u>Answer:</u> The pH of the solution is 2.74.
<u>Explanation:</u>
To calculate the pH of the acidic buffer, the equation for Henderson-Hasselbalch is used:
.......(1)
The power of the acid dissociation constant is the negative logarithm of the acid dissociation constant. The equation for it is:
......(2)
The chemical equation for the reaction of acetic acid and NaOH follows:
Given values:
Putting values in equation 2:
We are given:
= 0.1 M
= 0.001 M
Plugging values in equation 1:
Hence, the pH of the solution is 2.74.
I would say C. Since the material is getting warmer, the atoms and molecules will start to move fasten and then also create more "messiness" (which is entropy with a less-nice word)
Humus forms when plant and animal matter decay and particle size have different elements such as clay and sand with sand being the biggest
