Ionic bonds are made up of a metal and a nonmetal elements while covalent bonds are are made up of two metal. So, you can just look at the periodic table and identify which compounds have two metals and which have one metal and one nonmetal. Also, those compounds with high electronegativity difference are very likely to be ionic while the opposite is covalent. HOWEVER, some compounds can be both covalent and ionic. For instance, if HCI gas is at higher temperatures, then it is ionic while it would be covalent at room temp.
Hope I've helped.

D. all of these
Explanation:
All of given choices are the physical properties of the gold as given by the table.
Color is also a physical property.
Ionization potential and electronegativity are chemical properties of the metal.
The physical property of a substance tells us everything about a substance when no change is occurring to it.
Such properties are observed with our sense or instruments or pieces of apparatus.
- Examples are color of matter, state of matter, odor, taste, density, boiling point, melting point, solubility, hardness, texture etc

Answer:
12.044 ×10²³ molecules of HCl
Explanation:
Given data:
Number of moles of MgO = 1 mol
Number of molecules of HCl react = ?
Solution:
Chemical equation:
MgO + 2HCl → MgCl₂ + H₂O
with 1 mole of MgO 2 moles of HCl are react.
Number of molecules of HCl react:
1 mole contain 6.022×10²³ molecules
2 mol × 6.022×10²³ molecules / 1 mol
12.044 ×10²³ molecules
