Answer:
1.4% NaCl solution is Hypertonic
Explanation:
A hypertonic solution is type of solution that has a greater concentration of solutes (substance given in a solution) on the outside of a cell when compared with the inside of a cell.
Any solution of sodium chloride (NaCl) in water with a concentration of NaCl higher than that found in physiological saline (0.9%) is considered to be hypertonic
Protons and neutrons give the ATOMIC MASS
Answer:
It dissolves into the water
Na₂SO₄ + H₂O → 2Na₊_{aq} + SO₄²-_{aq}
Hope this helps :)

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
