write balanced equations of hydrogen with the following:
a. potassium b. fluorine c. sulfur
To write the balanced equations of hydrogen with potassium, fluorine, and sulfur, we need to consider the combining capacity or valency of each element.
a. Hydrogen with Potassium:
Potassium is an alkali metal with a valency or combining capacity of 1. Hydrogen also has a valency of 1. This means that one atom of hydrogen will react with one atom of potassium.
The balanced equation is:
2K + 2H₂ -> 2KH₂
b. Hydrogen with Fluorine:
Fluorine is a halogen with a valency of 1. Hydrogen, as mentioned earlier, also has a valency of 1. Hence, one atom of hydrogen will react with one atom of fluorine.
The balanced equation is:
H₂ + F₂ -> 2HF
c. Hydrogen with Sulfur:
Sulfur is a non-metal with a valency of 2. Hydrogen still has a valency of 1. Therefore, two atoms of hydrogen will react with one atom of sulfur to balance the charges.
The balanced equation is:
2H₂ + S₈ -> 8H₂S
In summary:
a. 2K + 2H₂ -> 2KH₂
b. H₂ + F₂ -> 2HF
c. 2H₂ + S₈ -> 8H₂S
