<u>Answer:</u> The volume of NaOH required to reach the endpoint is 100 mL
<u>Explanation:</u>
To calculate the volume of NaOH, we use the equation given by neutralization reaction:
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
are the n-factor, molarity and volume of acid which is ![CH_3COOH](https://tex.z-dn.net/?f=CH_3COOH)
are the n-factor, molarity and volume of base which is NaOH.
We are given:
![n_1=1\\M_1=0.250M\\V_1=50.0mL\\n_2=1\\M_2=0.125M\\V_2=?mL](https://tex.z-dn.net/?f=n_1%3D1%5C%5CM_1%3D0.250M%5C%5CV_1%3D50.0mL%5C%5Cn_2%3D1%5C%5CM_2%3D0.125M%5C%5CV_2%3D%3FmL)
Putting values in above equation, we get:
![1\times 0.250\times 50.00=1\times 0.125\times V_2\\\\V_2=\frac{1\times 0.250\times 50.0}{1\times 0.125}=100mL](https://tex.z-dn.net/?f=1%5Ctimes%200.250%5Ctimes%2050.00%3D1%5Ctimes%200.125%5Ctimes%20V_2%5C%5C%5C%5CV_2%3D%5Cfrac%7B1%5Ctimes%200.250%5Ctimes%2050.0%7D%7B1%5Ctimes%200.125%7D%3D100mL)
Hence, the volume of NaOH required to reach the endpoint is 100 mL
<u>Answer</u>:
"weathering breaks rocks into minerals and plants die and decay" must occur to form soil
<u>Explanation</u>:
For the formation of the soil two process are mandatory and they are erosion as well as weathering. The weathering takes place near the surface of the soil, which can occur due to various physical and chemical processes. Being an important part of soil development. It may occur rapidly or can be a slow process for decades. Water and air helps in weathering. The transport is generally by wind or with the help of flow of water, ice, etc
.,
If the patient has to take 2 tablets every 8 hours for 7 days.
24/8=3 3*2=6
this means that he patient will have to take 6 tablets every day.
6*7=42 And the patient must take 42 tablets in all 7 days
Hope this helps! :)
