Identify the base in the reaction (CH3)3N(aq) + HCl(aq) → (CH3)3NH+(aq) + Cl−(aq) 1. (CH3)3NH+(aq) 2. Cl−(aq) 3. (CH3)3N(aq) 4.

Answer:

(CH3)3N(aq)

Explanation:

We have to think of the definition of acid and base in the sense of Brownstead-Lowry. The Brønsted–Lowry theory is an acid–base reaction theory which was proposed independently by Johannes Nicolaus Brønsted and Thomas Martin Lowry in 1923.

A Bronsted-Lowry acid is a chemical species that donates one or more hydrogen ions in a reaction. In contrast, a Bronsted-Lowry base accepts hydrogen ions. When it donates its proton, the acid becomes its conjugate base. A more general approach to the theory is viewing an acid as a proton donor and a base as a proton acceptor.

If we look at the reaction closely, we can see that (CH3)3N(aq) accepted a proton. According to the definition above, we will have to classify (CH3)3N(aq) as a base. Hence the answer.

zzz [600]

Answer:

The energy of atomic orbitals increases as the principal quantum number, n, increases. In any atom with two or more electrons, the repulsion between the electrons makes energies of subshells with different values of l differ so that the energy of the orbitals increases within a shell in the order s < p < d < f.

Calculate the volume in (L) of 1.13x10^5 grams of liquid sodium which has a density of 0.929g/cm3
Yuki888 [10]

The volume of the liquid sodium is 121.64 L

<h3>What is density? </h3>

The density of a substance is simply defined as the mass of the subtance per unit volume of the substance. Mathematically, it can be expressed as

Density = mass / volume

With the above formula, we can obtain the volume of the liquid. Details below

<h3>How to determine the volume of the sodium liquid</h3>
  • Mass of liquid = 1.13×10⁵ g
  • Density of liquid = 0.929 g/cm³
  • Volume of liquid =?

Density = mass / volume

Thus,

Volume = mass / density

Volume of liquid = 1.13×10⁵ / 0.929

Volume of liquid = 121636.17 cm³

Divide by 1000 to express in liter

Volume of liquid = 121636.17 / 1000

Volume of liquid = 121.64 L
