5.5 moles
2.0=x/2.75
2.0*2.75= x/2.75 (2.75)
5.5=x
Answer:
2
Explanation:
There are 3 carbons on the right side
there are only two on the left side....you need one more ...so add one more... change the '1' coefficient in front of C to '2'
Answer:
1. The balanced equation is given below:
C4H6O3 + H2O → 2C2H4O2
The coefficients are: 1, 1, 2
Explanation:
C4H6O3 + H2O → C2H4O2
The above equation can be balanced as follow:
There are 4 atoms of C on the left side and 2 atoms on the right side. It can be balance by putting 2 in front of C2H4 O2 as shown below:
C4H6O3 + H2O → 2C2H4O2
Now, the equation is balanced as the number of atoms of the different elements present on both sides of the equation are equal.
The coefficients are: 1, 1, 2
The volume of the 18M HCl needed to make the solution will be 2.5 mL.
<h3>Dilution</h3>
According to the dilution principle, the number of moles of solutes in a solution before and after dilution must remain the same.
Since, mole = molarity x volume
Thus, molarity x volume before dilution = molarity x volume after dilution.
Mathematically, the equation is written as: m1v1 = m2v2
In this case, m1 = 18 M, m2 = 1.5 M, and v2 = 30 mL.
What we are looking for is v1, the amount of the stock HCl needed for dilution.
v1 = m2v2/m1 = 1.5 x 30/18 = 2.5 mL.
Thus, 2.5 mL of the stock HCl would be needed.
