What is the formula for table salt?
-
Na1Cl1
-
Na2Cl2
-
Na2Cl1
-
Na1Cl2
Correct Answer
A. Na1Cl1Explanation
The correct answer is NaCl, which represents table salt. Sodium chloride (NaCl) is composed of one sodium ion (Na+) and one chloride ion (Cl-). The subscript numbers indicate the ratio of the ions in the compound, with one sodium ion and one chloride ion combining to form the stable salt compound.Rate this question:

-
(NH)(NO)
-
(NH3)(NO3)
-
(NH4)(NO3)
-
(NH4)(NO2)
Correct Answer
A. (NH4)(NO3)Explanation
Ammonium nitrate is a compound made up of ammonium ions (NH4+) and nitrate ions (NO3-). The formula (NH4)(NO3) represents the correct combination of these ions in the compound.Rate this question:

What is the charge on the ion of any halogen?
-
+1
-
+2
-
-1
-
-2
Correct Answer
A. -1Explanation
The charge on the ion of any halogen is -1. This is because halogens have seven valence electrons and need to gain one more electron to achieve a stable octet. By gaining one electron, they acquire a negative charge of -1, forming halide ions.Rate this question:

What is the stock name given to the following ionic compound... CuCl2?
-
Copper (I) chloride
-
Copper (II) chloride
-
Copper (III) chloride
-
Cupric chloride
Correct Answer
A. Copper (II) chlorideExplanation
The stock name given to the ionic compound CuCl2 is copper (II) chloride. This is because the Roman numeral II in parentheses indicates that the copper ion in the compound has a +2 charge. Since chloride ions have a -1 charge, two chloride ions are needed to balance the charge of the copper ion. Therefore, the correct stock name for CuCl2 is copper (II) chloride.Rate this question:

What is the charge on the lead ion (Pb) in the following formula... PbO?
-
+1
-
+2
-
+3
-
+4
Correct Answer
A. +2Explanation
In the compound PbO, the oxygen atom has a charge of -2. Since the overall compound is neutral, the charge on the lead ion (Pb) must be +2 to balance out the -2 charge from the oxygen atom. Therefore, the correct answer is +2.Rate this question:

What is the stock name for the ionic compound with the formula of... Cu(NO3)
-
Copper (II) nitrate
-
Copper (II) nitrite
-
Copper (I) nitrate
-
Copper nitride
Correct Answer
A. Copper (I) nitrateExplanation
The correct answer is copper (I) nitrate. This is because the formula Cu(NO3) indicates that there is one copper ion with a +1 charge, and one nitrate ion with a -1 charge. Therefore, the compound is named copper (I) nitrate. Copper (II) nitrate would indicate a copper ion with a +2 charge, which is not present in the formula. Copper (II) nitrite and copper nitride are not correct because they do not match the formula given.Rate this question:

Which of the following is a property of binary ionic compounds?
-
They conduct electricity in their solid state.
-
They are usually soluble in non-polar solvents.
-
They are brittle and can shatter when struck.
-
They have low melting and boiling points.
Correct Answer
A. They are brittle and can shatter when struck.Explanation
Binary ionic compounds are typically brittle because their crystal lattice structure is rigid. When a force is applied, it can cause like-charged ions to be forced close together, resulting in repulsion and shattering the crystal along specific planes.Rate this question:
