Answer: Thus molarity of
is 1.35 M
Explanation:
To calculate the volume of acid, 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 ![HNO_3](https://tex.z-dn.net/?f=HNO_3)
are the n-factor, molarity and volume of base which is KOH.
We are given:
![n_1=1\\M_1=?M\\V_1=10.0mL\\n_2=1\\M_2=1.0M\\V_2=13.5mL](https://tex.z-dn.net/?f=n_1%3D1%5C%5CM_1%3D%3FM%5C%5CV_1%3D10.0mL%5C%5Cn_2%3D1%5C%5CM_2%3D1.0M%5C%5CV_2%3D13.5mL)
Putting values in above equation, we get:
![1\times M_1\times 10.0=1\times 1.0\times 13.5\\\\M_1=1.35M](https://tex.z-dn.net/?f=1%5Ctimes%20M_1%5Ctimes%2010.0%3D1%5Ctimes%201.0%5Ctimes%2013.5%5C%5C%5C%5CM_1%3D1.35M)
Thus molarity of
is 1.35 M
Answer:
14.68 oz
Explanation:
The mean volume is the average volume of all the regular soda cans put together; 14.5 oz. The standard deviation 0.18 oz is the maximum deviation from the mean. It can be 14.5-0.18= 14.32 oz which is the usual minimum or 14.5 + 0.18=14.68 oz which is the usual maximum
Answer:
D
Explanation:
Option D is the correct Lewis structure of ozone.
Ozone is known to be an allotrope of oxygen which has three atoms of oxygen.
In the Lewis structure of ozone, one pair of oxygen is actually double-bonded while the other is single-bonded. In this structure, two oxygen atoms carry charges. In the drawing the Lewis structure of ozone, we discover that one oxygen atom of the ozone has a -1 charge and while another oxygen atom of the ozone has a +1 charge.
