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.

199.5 grams unrefined dark crystalline sugar to cups
Dmitry [639]

Answer:

0.9975 cup  

Step-by-step explanation:

"Unrefined dark crystalline sugar" is what non-chemists call "brown sugar."

200.0 g brown sugar = 1 cup

 199.5 g brown sugar = 199.5× 1/200 .0

 199.5 g brown sugar = 0.9975 cup

A standard measuring cup is not capable of this precision and, furthermore, the mass of brown sugar you can get into a cup depends on how tightly you pack it.

Your Mole Day cake will be fine if you use 1 cup of brown sugar as usual.
