A Lewis acid-base reaction occurs when a base donates a pair of electrons to an acid. ... A Brønsted-Lowry acid such as HCl is an acid-base adduct according to the Lewis concept, and proton transfer occurs because a more stable acid-base adduct is formed.

Example: Water (H2O) has two nonbonding pairs of electrons, so it donates one pair to the carbocation. As a result, one bond is formed and shared between carbon and oxygen. Water acts as a Lewis base because it is the electron pair donor in this reaction.

Lakshmi has a sample of ammonium nitrate (NH4NO3) that has a mass of 40.10 g. She knows that the molar mass of NH4NO3 is 80.0432
avanturin [10]
The answer is 0.5010

Number of moles (n) is equal to the quotient of mass (m) and molar mass of a sample (Mr):
n = m/Mr

We have:
n = ?
m = 40.10 g
Mr = 80.0432 g/mol

n = 40.10 g : 80.0432 g/mol = 0.5010

<span>40.10 has 4 significant digits,
</span><span>80.0432 has 6 significant digits.
Since 4 is less than 6, we choose 4 </span>significant digits
