An insoluble solid that forms from a chemical reaction is called a(n) _____.
serious [3.7K]
I believe that an insoluble solid that forms a chemical reaction is called a precipitate. 
Precipitate is an insoluble solid that forms when two ionic compounds in solution are combined. Which means precipitation reaction is the creation of a solid from a solution, and when the reaction occurs in a liquid solution, the solid formed is called the precipitate. In fact the only method of forming insoluble salts is called precipitation or double decomposition of salts.

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

How can forgery be used in crime
Tems11 [23]

Some bad people will tend to forge dollar bills and make fake bills, giving them to cashiers and asking for it to be split into a different amount of bills so they are given real cash and wont be caught or they will buy things, return them and be given back real money and get away with it. This is obviously a crime because it's fake.
