Convert 1.50μm2 to square meters

IrinaVladis [17]

1 micro meter = $10^{-6} meters$
1 μm ^2 = 1 μm*1μm = $10^{-6} *10^{-6} = 10^{-12}$ meters

1.5 μm^2 = 1.5 * $10^{-12}$ meters

μm^2 is a unit for surface. First you want to convert μm to meters which is unit for length and if you multiply units for length you get unit for surface.

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.
