6. Why are ionic substances not known as molecules?

Chemistry

Answer:

So, an ionic compound actually has two (or even more) different species in a single crystal or solution, which exist independently. The only reason why they are together is because of the total net charge, which must be zero.

Answer: ionic compounds are not known as molecules because they contain aggregate of positive and negative charges which arise from the transfer of electron from the metallic atom to the non-metallic atom. But in covalent substance, there is a sharing of electron pair between the atoms involved and this makes them to form a molecules

Answer:

0.131 mol

Explanation:

To convert grams to moles, you need to use the molar mass.  The molar mass is the mass number.  You can find this on the periodic table.  The molar mass of sodium is 22.990 g/mol.

(3.02 g)/(22.990 g/mol) = 0.131 mol

Write the complete balanced equation for the reaction between CaCO3 and KCI
EleoNora [17]

CaCO3 + 2KCL ⇒ CaCl2 + K2CO3

It is balanced as so based on the charges given on the periodic table and polyatomic ions.

Calcium has the charge of 2 but CO3 also shares the same charge, thus cancelling that out.

Potassium has a charge of 1 while Chlorine also shares a charge of 1, also cancelling it out.

Thus, if it performs a double replacement reaction, they would take these charges to the new elements that do not cancel out their charges.

Therefore, we need the coefficient of 2 in front of Potassium Chloride in order to balance the equation as on the products side of the equation, Potassium and Chlorine both have a subscript of 2.

Hope this helps!
