We know that
pH = -log[H+]
the pH value falls in between 0- 7 for acids
As the pH value increases the concentration of [H+] increases.
similarly as the value of pH approaches 0, the concentration of H+ increases
The solution said to become more acidic
Also
[H+] X [OH-] = 10^-14
Thus pH + pOH = 14
hence the concentration of OH- decreases as the pH approaches zero
Answer:
To balance a reaction, the amount of reactants must be equal to the amount of products, as stated by the Law of Conservation of Matter. It may help you to keep track of the number of each element in a list as you try to balance. It's not able to be balanced.
Answer:
B and D
Explanation:
it is B and D because in no gravity if you change the size of the ball it does not change anything. and if you swing fast it does not change anything but the speed. if you change the angle it is just the same modle but different angle
Answer: 323.61 g of
will be produced
Explanation:
The given balanced chemical reaction is :

According to stoichiometry :
2 moles of
require 1 mole of 
Thus 3.00 moles of
will require=
of 
Thus
is the limiting reagent as it limits the formation of product.
As 2 moles of
give = 2 moles of 
Thus 3.00 moles of
give =
of 
Mass of 
Thus 323.61 g of
will be produced from the given moles of both reactants.
The given solution is a mixture of
and
. It acts as a buffer as it is a combination of the weak acid
and it's conjugate base
.
![[Acid] = [HCO_{3}^{-}]=1.0 M](https://tex.z-dn.net/?f=%5BAcid%5D%20%3D%20%5BHCO_%7B3%7D%5E%7B-%7D%5D%3D1.0%20M)
![[Base] =[CO_{3}^{2-}]=0.1 M](https://tex.z-dn.net/?f=%5BBase%5D%20%3D%5BCO_%7B3%7D%5E%7B2-%7D%5D%3D0.1%20M)
pH of the buffer solution can be calculated from Hendersen-Hasselbalch equation as below:
![pH=pK_{a}+log\frac{[CO_{3}^{2-}]}{[HCO_{3}^{-}]}](https://tex.z-dn.net/?f=pH%3DpK_%7Ba%7D%2Blog%5Cfrac%7B%5BCO_%7B3%7D%5E%7B2-%7D%5D%7D%7B%5BHCO_%7B3%7D%5E%7B-%7D%5D%7D)

pH = 10.33+(-1)
= 9.33
