The answer should be B, ionic bond.
Ionic bond is the bonding between a metal and a non-metal. While covalent bond is the bond between non-metals, and metallic bond is the bond between metals.
Since Na, sodium, is a metal, and Cl, chlorine, is a non-metal, the bond formed between them is an ionic bond. Sodium gives up an electron to chlorine inside this bonding.
I think it's 11.56 minutes
See if it is telling you to add them lol
Answer:
The amount of molecules → 6.02×10²³
Explanation:
Avogadro Number (NA) is the amount of particles that are contained in 1 mol of anything.
It does not matter the mass of compounds, or molecules, 1 mol has 6.02×10²³ particles, the same number for every compound.
1 mol of H₂O that weighs 18 grams has 6.02×10²³ molecules
1 mol of sucrose, that weighs 342 g has 6.02×10²³ molecules
Generally, the NA is the number of atoms in 12 grams of the carbon-12 isotope.
Moles 
neutralized = moles 
neutralized at the equivalence point of a titration. Hence, option A is correct.
<h3>
What is titration?</h3>
A method or process of determining the concentration of a dissolved substance in terms of the smallest amount of reagent of known concentration required to bring about a given effect in reaction with a known volume of the test solution.
Equivalence point: point in titration at which the amount of titrant added is just enough to completely neutralize the analyte solution.
At the equivalence point in an acid-base titration, moles of base = moles of acid and the solution only contains salt and water.
Hence, option A is correct.
