To develop the chemical formula of a substance or compound in this regard, one only needs to write the chemical symbol for each of the element present and write as subscript to each symbol the number of atoms of that element. For nitrobenzene, as described above, the chemical formula should be,
C₆H₅O₂N
Answer:
1.17 grams of HCl can neutralize 2.7 grams sodium bicarbonate
Explanation:
Step 1: Data given
Mass of sodium bicarbonate = 2.7 grams
Step 2: The balanced equation
HCl + NaHCO3 ⇔ NaCl + H2O + CO2
Step 3: Calculate moles NaHCO3
moles NaHCO3 =2.7 g / 84 g/mol= 0.032 moles
Step 4: Calculate moles HCl
For 1 mol NaHCO3 we need 1 mol HCl
For 0.032 moles NaHCO3 = 0.032 moles HCl
Step 5: Calculate mass HCl
Mass HCl = moles HCl * molar mass HCl
mass HCl = 0.032 * 36.46 g/mol= 1.17 grams
1.17 grams of HCl can neutralize 2.7 grams sodium bicarbonate
Answer:
The new pH of the solution 
Explanation:
Given
pH of bottle of Soda is 
As we know that
pH 
log [H+]
We will derive the hydrogen ion concentration when pH is
log [H+]
Taking anti-log on both the sides, we get -
H+ ion is equal to 
When the hydronuim ion concentration reduces by 
of the original concentration, the new hydrogen ion concentration becomes
The new pH is
![= - log [ 10^{-6}]\\= 6](https://tex.z-dn.net/?f=%3D%20-%20log%20%5B%2010%5E%7B-6%7D%5D%5C%5C%3D%206)
