Fire transfers heat by CONVECTION, meaning some heat rises, and FALL, meaning some heat goes out in every directions.
Hope that helps!!!
Answer:
This question is incomplete
Explanation:
This question is incomplete but what you should know is that isopropanol (also referred to rubbing alcohol) has just one functional group. This functional group is called the hydroxyl group (-OH) and it's the reason the compound name ends with "ol". The hydroxyl group can be seen in the structure of the compound (Isopropanol) below
H OH H
| | |
H- C - C - C - H
| | |
H H H
If there is any functional group in isopropanol required for any form of interaction, that functional group will be the hydroxyl group because that's the only functional group isopropanol has.
NOTE: Functional group is an atom or group of atoms that determines the chemical properties of a compound.
Answer:
0.146 M
Explanation:
Equation for the reaction :
2A(aq) ↔ B(aq) + C(aq)
= 65
Molar concentration of A = 
= 2.5 M
2A(aq) ↔ B(aq) + C(aq)
Initial 2.50 0 0
Change - 2x + x + x
Equilibrium 2.50 - 2x +x +x
![K_c =\frac {[B][C]}{[A]^2}](https://tex.z-dn.net/?f=K_c%20%3D%5Cfrac%20%7B%5BB%5D%5BC%5D%7D%7B%5BA%5D%5E2%7D)
![65 = \frac{[x][x]}{[2.5-2x]^2}](https://tex.z-dn.net/?f=65%20%3D%20%5Cfrac%7B%5Bx%5D%5Bx%5D%7D%7B%5B2.5-2x%5D%5E2%7D)
![65 = \frac{[x]^2}{[2.5-2x]^2}](https://tex.z-dn.net/?f=65%20%3D%20%5Cfrac%7B%5Bx%5D%5E2%7D%7B%5B2.5-2x%5D%5E2%7D)
![65 = (\frac{[x]}{[2.5-2x]})^2](https://tex.z-dn.net/?f=65%20%3D%20%28%5Cfrac%7B%5Bx%5D%7D%7B%5B2.5-2x%5D%7D%29%5E2)
![\sqrt 65 = \sqrt {(\frac{[x]}{[2.5-2x]})^2}](https://tex.z-dn.net/?f=%5Csqrt%2065%20%3D%20%20%5Csqrt%20%7B%28%5Cfrac%7B%5Bx%5D%7D%7B%5B2.5-2x%5D%7D%29%5E2%7D)
8.062(2.5 - 2x) = x
20.155 - 16.124x = x
20.155 = 16.124x+x
20.155 = 17.124x
x = 
x = 1.177
[A] = 2.5 - 2x
= 2.5 - 2(1.177)
= 0.146 M
Therefore, the equilibrium concentration of A = 0.146 M
