Answer:
A the pressure is changed to 0.8
Explanation:
Boyles gas law
Answer:
She added the ingredients in the wrong order, this will make the ingredients to mix in a different way and that can lead to different errors, formation of clumps is one of them.
Answer:
The ratio, ![\frac{[HCO_{3}^{-}]}{[H_{2}CO_{3}]}](https://tex.z-dn.net/?f=%5Cfrac%7B%5BHCO_%7B3%7D%5E%7B-%7D%5D%7D%7B%5BH_%7B2%7DCO_%7B3%7D%5D%7D)
, is 10.7
Explanation:
is an weak acid and 
is it's conjugate base.
So, according to Henderson-Hasselbalch equation, pH of this buffer system can be represented as-
![pH=pK_{a}(H_{2}CO_{3})+log(\frac{[HCO_{3}^{-}]}{[H_{2}CO_{3}]})](https://tex.z-dn.net/?f=pH%3DpK_%7Ba%7D%28H_%7B2%7DCO_%7B3%7D%29%2Blog%28%5Cfrac%7B%5BHCO_%7B3%7D%5E%7B-%7D%5D%7D%7B%5BH_%7B2%7DCO_%7B3%7D%5D%7D%29)
Here pH=7.40, 
=6.37
So, ![7.40=6.37+log(\frac{[HCO_{3}^{-}]}{[H_{2}CO_{3}]})](https://tex.z-dn.net/?f=7.40%3D6.37%2Blog%28%5Cfrac%7B%5BHCO_%7B3%7D%5E%7B-%7D%5D%7D%7B%5BH_%7B2%7DCO_%7B3%7D%5D%7D%29)
or, ![\frac{[HCO_{3}^{-}]}{[H_{2}CO_{3}]}=10.7](https://tex.z-dn.net/?f=%5Cfrac%7B%5BHCO_%7B3%7D%5E%7B-%7D%5D%7D%7B%5BH_%7B2%7DCO_%7B3%7D%5D%7D%3D10.7)
So the ratio, , is 10.7
