Answer 3

a) Cl2 + Fe = ?

The given equation is a combination reaction between chlorine gas (Cl2) and iron (Fe). In a combination reaction, two or more substances combine to form a single product. To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

The balanced equation for the reaction between chlorine gas and iron is:

Cl2 + 2Fe = 2FeCl2

In this balanced equation, there are 2 chlorine atoms and 2 iron atoms on both sides.

b) Cl2 + Zn = ?

The given equation is a combination reaction between chlorine gas (Cl2) and zinc (Zn). To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

The balanced equation for the reaction between chlorine gas and zinc is:

Cl2 + Zn = ZnCl2

In this balanced equation, there are 2 chlorine atoms and 1 zinc atom on both sides.

c) Cl2 + H2 = ?

The given equation is a combination reaction between chlorine gas (Cl2) and hydrogen gas (H2). To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

The balanced equation for the reaction between chlorine gas and hydrogen gas is:

Cl2 + H2 = 2HCl

In this balanced equation, there are 2 chlorine atoms and 2 hydrogen atoms on both sides.

d) Cl2 + Na = ?

The given equation is a combination reaction between chlorine gas (Cl2) and sodium (Na). To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

The balanced equation for the reaction between chlorine gas and sodium is:

Cl2 + 2Na = 2NaCl

In this balanced equation, there are 2 chlorine atoms and 2 sodium atoms on both sides.

e) Cl2 + Cu = ?

The given equation is a combination reaction between chlorine gas (Cl2) and copper (Cu). To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation.

The balanced equation for the reaction between chlorine gas and copper is:

Cl2 + 2Cu = 2CuCl2

In this balanced equation, there are 2 chlorine atoms and 2 copper atoms on both sides.

f) Cl2 + H2O = ?

The given equation is a redox reaction between chlorine gas (Cl2) and water (H2O). To balance the equation, we need to ensure that the number of atoms of each element and the charge is equal on both sides of the equation.

The balanced equation for the reaction between chlorine gas and water is:

Cl2 + H2O = HCl + HClO

In this balanced equation, there are 2 chlorine atoms, 2 hydrogen atoms, and 1 oxygen atom on both sides.
