Ammonia is NH3, meaning there are three bonds. All three bonds are between nitrogen and hydrogen, one each per hydrogen atom. If dissolved in water, they can also be called ammonium hydroxide. (NH4OH)

Based on observation of polar and non-polar molecules, polar molecules would attract each other more strongly.
<h3>What are polar and non-polar molecules?</h3>
Polar molecules are those molecules that can ionize or dissociate into their respective positive and negative ions when in an aqueous solution.
Nonpolar molecules, on the other hand, are not ionic i.e. not dissociating into ions when dissolved in water.
Polar molecules like water (H2O) contains an uneven distribution of cations (+) and anions (-), hence, would be more attracted to one another than nonpolar molecules that have an even distribution of ions.

I think it can change the paperclip's color.
Answer:
Explanation:
1. Calculate the rate constant
The integrated rate law for first order decay is
where
A₀ and A_t are the amounts at t = 0 and t
k is the rate constant
2. Calculate the half-life
