An old 0.500 L lecture bottle of triethylamine (N(CH₂CH₃)₃) was found in a lab and needed for a synthesis reaction. A pressure r
Tatiana [17]

Mass of vaporized triethylamine : 2.606 g

<h3>Further explanation</h3>

Given

0.5 L triethylamine

P = 18.5 psi

T = 25 °C

Required

mass of vaporized triethylamine

Solution

Conversion :

P 18.5 psi = 1,26 atm

T = 25 +273 = 298 K

Ideal gas law :

PV=nRT

n = PV/RT

Input the value :

n = (1.26 atm x 0.5 L) /(0.08205 x 298)

n = 0.0258

MW triethylamine = 101 g/mol

Mass  triethylamine :

= n x MW

= 0.0258 x 101 g/mol

= 2.606 g

Answer:

<u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.

Correct answer - C

Explanation:

A solid sodium metal reacts with gaseous form of chlorine gas to form  a solid sodium chloride.

This formation of sodium chloride arises due to transfer of one valence electron from sodium to chlorine atom and the both atoms get stable octet electronic configuration.

As a result, an ionic compound solid sodium chloride is formed.

The chemical reaction of formation sodium chloride is as follows.

2Na(s)+Cl_{2}(g) \rightarrow 2NaCl(s)

Therefore, <u>only sodium chloride compounds</u> MOST LIKELY products of the reaction between sodium metal and chlorine gas.
