How to write a balanced chemical equation from empirical formula?

netineya [11]

Let's use the example: H2O ---> H2 + O2
We find how many elements of a product are on one side and how many elements on the other side.
Reactant: H=2 O=1
Product: H=2 O=2
We need to make the same amount of hydrogen and oxegyn atoms on each side, regardless of how high the numbers are, and we do this by adding coefficients to the compounds.

Reactant: H=4 O=2
Product : H=4 O=2
2 H2O---> 2 H2 + O2

Is ammonium ion a bronsted base

Leokris [45]

Unlikely. It's unlikely for ammonium ion ${\text{NH}_4}^{+}$ to accept a proton $\text{H}^{+}$ and act as a Bronsted-Lowry Acid.

<h3>Explanation</h3>

What's the definition of Bronsted-Lowry acids and bases?

Bronsted-Lowry Acid: a species that can donate one or more protons $\text{H}^{+}$ in a reaction.

Bronsted-Lowry Base: a species that can accept one or more protons $\text{H}^{+}$

Ammonium ions ${\text{NH}_4}^{+}$ are positive. Protons $\text{H}^{+}$ are also positive.

Positive charges repel each other, which means that it will be difficult for ${\text{NH}_4}^{+}$ to accept any additional protons. As a result, it's unlikely that ${\text{NH}_4}^{+}$ will accept <em>any</em> proton and act like a Bronsted-Lowry Base.
