Answer:
Lewis Structure:
Explanation:
CO2 Lewis Structure
So CO2 = 4 + 6(2) = 16. So, total valence electrons are 16. Carbon is the least electronegative that means it stays at the center. So, put the Carbon in the middle and then set the oxygen either side of that.

Answer:
I believe its A. Mass
Explanation:
An intensive property is a property of matter that depends only on the type of matter in a sample and not on the amount. For example, the electrical conductivity of a pure substance is a property that depends only on the type of substance. Silver, gold, and copper are excellent conductors of electricity, while glass and plastic are poor conductors.. Other intensive properties include color, temperature, density, and solubility.
Answer : The concentration of the
is, 0.115 M
Explanation :
Using dilution law,
![n_1M_1V_1=n_2M_2V_2](https://tex.z-dn.net/?f=n_1M_1V_1%3Dn_2M_2V_2)
where,
= basicity of an acid = 1
= acidity of a base = 1
= concentration of
= 0.125 M
= concentration of KOH = ?
= volume of
= 25 ml
= volume of NaOH = 27.07 ml
Now put all the given values in the above law, we get the concentration of the
.
![1\times 0.125M\times 25ml=1\times M_2\times 27.07ml](https://tex.z-dn.net/?f=1%5Ctimes%200.125M%5Ctimes%2025ml%3D1%5Ctimes%20M_2%5Ctimes%2027.07ml)
![M_2=0.115M](https://tex.z-dn.net/?f=M_2%3D0.115M)
Therefore, the concentration of the
is, 0.115 M
