Chemistry

6 0

Answer:

2AgNO3 + Cu = Cu(NO3)2 + 2Ag

Explanation:

First you see which side has the most elements. Which is Cu(NO3)2 + Ag. But, both sides have the same elements? But, on the reactants side, there is 2 of NO3. On the products side there is only one.

Reactants:            Products:

Cu = 1                    Cu = 1

NO3 = 1                 NO3 = 2

Ag = 1                    Ag = 1

They are all equal, except for NO3. So on the reactants side, you add a two to make it even.

2AgNO3 + Cu = Cu(NO3)2 + Ag

Reactants:            Products:

Cu = 1                    Cu = 1

NO3 = 2                NO3 = 2

Ag = 2                   Ag = 1

Now, the NO3 is equal, But the Ag isn't. But, you can add a 2 on the <u>products</u> side so the whole equation becomes equal.

2AgNO3 + Cu = Cu(NO3)2 + 2Ag

Reactants:            Products:

Cu = 1                    Cu = 1

NO3 = 2                NO3 = 2

Ag = 2                   Ag = 2

_____Mg + ____Fe2O3 → _____Fe + ____MgO
german

Answer:

3Mg + Fe₂O₃  → 2 Fe + 3MgO

Explanation:

Chemical equation;

Mg + Fe₂O₃  →  Fe + MgO

Balanced Chemical equation;

3Mg + Fe₂O₃  → 2Fe + 3MgO

This is the balanced equation. There are three magnesium, two iron and three oxygen atoms are on both side of equation thus it follow the law of conservation of mass.

Law of conservation of mass:

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.
