Answer : The hydroxide ion concentration of a solution is, 
Explanation :
As we know that 
dissociates in water to give hydrogen ion 
and carbonate ion 
.
As, 1 mole of dissociates to give 1 mole of hydrogen ion
Or, 1 M of dissociates to give 1 M of hydrogen ion
So, 0.200 M of dissociates to give 0.200 M of hydrogen ion
Now we have to calculate the hydroxide ion concentration.
As we know that:
![[H^+][OH^-]=1\times 10^{-14}](https://tex.z-dn.net/?f=%5BH%5E%2B%5D%5BOH%5E-%5D%3D1%5Ctimes%2010%5E%7B-14%7D)
![0.200\times [OH^-]=1\times 10^{-14}](https://tex.z-dn.net/?f=0.200%5Ctimes%20%5BOH%5E-%5D%3D1%5Ctimes%2010%5E%7B-14%7D)
![[OH^-]=5\times 10^{-14}](https://tex.z-dn.net/?f=%5BOH%5E-%5D%3D5%5Ctimes%2010%5E%7B-14%7D)
Therefore, the hydroxide ion concentration of a solution is,
Carbon dioxide is the other product created.
B.Prism because it’s triangular and a cylinder is circular
Answer:
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
Explanation:
Chemical formula = C₇H₈N₄O₂
Elements present:
carbon
hydrogen
nitrogen
oxygen
Number of atoms of each element.
carbon = 7 atoms
hydrogen = 8 atoms
nitrogen = 4 atoms
oxygen = 2 atoms
To determine the absolute pressure of this gas, all you need to do is to add the value of atmospheric pressure and the value of gage pressure.
Atmospheric pressure is equivalent to 100 kPa.
Gage pressure is 276 kPa.
Then, we add both values.
N = 100 kPa + 276 kPa
N = 376 kPa
The absolute pressure of this gas is 376 kPa.
Hope this helps :)
