Calcium chloride (CaCl2), an ionic compound
Answer:
The Ph is 3
Explanation:
First of all, calculate the concentration of the acid.
The balanced equation of reaction is:
HCl + NaOH ===> NaCl + H2O
Using titration equation of formula
CAVA/CBVB = NA/NB
Where NA is the number of mole of acid = 1 (from the balanced equation of reaction)
NB is the number of mole of base = 1 (from the balanced equation of reaction)
CA is the concentration of acid = ?
CB is the concentration of base = 0.1M
VA is the volume of acid = 100 mL
VB is the volume of base = 1mL
Substituting
CA×100/0.1×1 = 1/1
Therefore CA =0.1×1×1/100×1
CA = 0.001 M (this is the hydrogen ion concentration)
Ph of the acid is calculated using
Ph = -log [H+]
= -log 0.001
= 3
Hey there!
Fe + O₂ → Fe₂O
Let's start by balancing the oxygen.
There are two on the left and one on the right, so let's add a coefficient of 2 in front of Fe₂O.
Fe + O₂ → 2Fe₂O
Now let's balance the iron.
There is one on the left and four on the right, so let's add a coefficient of 4 in front of Fe.
4Fe + O₂ → 2Fe₂O
This is our final balanced equation.
Hope this helps!
