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.
bixtya [17]

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.

Involves combining of nuclei:
bogdanovich [222]

Explanation:

Involves combining of nuclei:  Nuclear fusion

Nuclear fusion is a radioactive reaction  in which small atomic nuclei combines into larger ones with the release of a large amount of energy. The energy released is used to furnish a series of chain reactions.

Produces dangerous radioactive waste:  Nuclear fission

Nuclear fission is used in powering most nuclear power plants. The products of these reactions are radioactive in nature. They are very dangerous to human health and the environment at large.

Have high activation energies:  Nuclear fusion

The activation energy is the energy barrier that must be overcome before a reaction starts. Nuclear fusion reactions require very high amount of energy input to overcome the activation needed to start the reaction.

Releases large amounts of energy:  Nuclear reactions

Both nuclear fusion and fission releases large amount of energy.

Occurs in the stars:  Nuclear fusion

Nuclear fusion occurs in stars and they involve the combination of atomic nuclei to form larger ones.

Drives chemical plants: Nuclear fission

Chemical plants uses electricity and nuclear power plants can produce electricity through nuclear fission.

Muriatic acid, an industrial grade of concentrated HCl, is used to clean masonry and cement. Its concentration is 11.7 M. For ro
Nata [24]

Answer:

\boxed{\text{199 mL}}

Explanation:

1. Calculate the moles of HCl  

n = \text{25.4 g} \times \dfrac{\text{1 mol}}{\text{36.46 g}} = \text{0.6967 mol}

2. Calculate the volume of dilute HCl

\begin{array}{rcl}\text{Molar concentration}& =& \dfrac{\text{moles}}{\text{litres}}\\\\3.50 & = & \dfrac{0.6967}{V}\\\\3.50V & = & 0.6967\\\\V & = & \dfrac{0.6967}{3.50}\\\\V & = & \text{0.199 L} =\textbf{199 mL}\end{array}\\\text{The volume of muriatic acid needed is }\boxed{\textbf{199 mL}}
