 Ions are electrically charged particles that are formed when certain compounds are dissolved in water. These solutions will conduct electricity. The Swedish scientist Svante Arrhenius coined the term ion (which means wanderer) to explain why solutions of electrolytes will conduct an electric current. When an electrolyte forms into a solution, it dissolves or dissociates into ions, a process called ionization. If a substance does not ionize, it will not conduct an electric current. Electrolytes include most acids, bases, and salts. Some conductors include hydrogen and sodium chloride, copper sulfate, and potassium nitrate. Substances that are not electrolytes include distilled water, sugar water, and most organic compounds. Which of the following is a non-electrolyte? 
 A) H 2 SO 4 (sulfuric acid)B) HCL (hydrochloric acid)C) C 3 H 8 (propane gas)D) NaCl (table salt)

Answers

answer: C
because propane gas is organic compound
This is the answer C because propane gas is the only which is a \n non-electrolyte. It's because propane gas is organic compound.

How many moles are in 22 grams of argon

Answers

Explanation:

It is known that number of moles equal mass divided by molar mass.

Mathematically,  Number of moles = (mass given)/(molar mass)

Since, it is given that mass is 22 grams and molar mass of argon is 40 g/mol.

Therefore,  Number of moles = (mass given)/(molar mass)

                                                 = (22 g)/(40 g/mol)

                                                 = 0.55 mol

Thus, we can conclude that there are 0.55 moles in 22 grams of argon.
number of moles are the amount of substance of an element .
number of moles can be calculated as follows;
number of moles = mass present / molar mass of element
molar mass of Ar - 40 g/mol
number of moles of Ar = 22 g / 40 g/mol = 0.55 mol .
there are 0.55 mol of Ar

a teacher describes a mathematical system that can be used to convert the weight of water to the mass of water

Answers

To describe a mathematical system that converts weight of water to mass equivalent, the teacher must use the idea of acceleration of gravity. Mass is the amount of matter composed in a substance. Weight is affected by the pull of gravity. Weight is mass multiplied by acceleration of gravity. Gravity acceleration is equal to 9.81 m/s2. So to convert weight to mass, divide the weight by 9.81 m/s2 simply.
