Answer:
Explanation:
Here, we want to get the equation of the reaction between Hydrochloric acid and Zinc metal
Zinc metal displaces the hydrogen from hydrochloric acid to form zinc chloride
We have the equation of reaction as:
both of the answers are bone
Explanation:

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
