Answer:
Chloroform= limiting reactant
0.209mol of CCl4 is formed
And 32.186g of CCl4 is formed
Explanation:
The equation of reaction
CHCl3 + Cl2= CCl4 + HCl
From the equation 1 mol of
CHCl3 reacts with 1mol Cl2 to yield 1mol of CCl4
From the question
25g of CHCl3 really with Cl2
Molar mass of CHCl3= 119.5
Molar mass of Cl2 = 71
Hence moles of CHCl3= 25/119.5 = 0.209mol
Moles of Cl2 = 25/71 = 0.352mol
Hence CHCl3 is the limiting reactant
Since 1 mole of CHCl3 gave 1mol of CCl4
It implies that 0.209moles of CHCl3 will also give 0.209mol of CCl4
Mass of CCl4 formed = moles× molar mass= 0.209×154= 32.186g
D is the correct answer......
hope it help, please thank me if it did.....
Answer:
Explanation:
Chemical equation:
FeCl₃ + NaOH → Fe(OH)₃ + NaCl
Balanced chemical equation:
FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
Step 1:
FeCl₃ + NaOH → Fe(OH)₃ + NaCl
Fe = 1 Fe = 1
Cl = 3 Cl = 1
Na = 1 Na = 1
OH = 1 OH = 3
Step 2:
FeCl₃ + 3NaOH → Fe(OH)₃ + NaCl
Fe = 1 Fe = 1
Cl = 3 Cl = 1
Na = 3 Na = 1
OH = 3 OH = 3
Step 3:
FeCl₃ + 3NaOH → Fe(OH)₃ + 3NaCl
Fe = 1 Fe = 1
Cl = 3 Cl = 3
Na = 3 Na = 3
OH = 3 OH = 3
Now we the equation is completely balanced and follow the law of conservation of mass because there are equal number of atoms of each elements are present on both side.
According to the law of conservation mass, mass can neither be created nor destroyed in a chemical equation.
This law was given by french chemist Antoine Lavoisier in 1789. According to this law mass of reactant and mass of product must be equal, because masses are not created or destroyed in a chemical reaction
.
Type of reaction:
It is double displacement reaction.
Double replacement:
It is the reaction in which two compound exchange their ions and form new compounds.
AB + CD → AC +BD
