0.69moles
Explanation:
Given parameters:
Number of atoms = 4.14 x 10²³atoms
Atom = Na
Unknown:
Number of moles of Na atom in it = ?
Solution:
A mole of a substance is the quantity of substance that contains the avogadro's number of particles.
1 mole = 6.02 x 10²³particles
To solve this problem, simply use the expression below;
Number of moles = 
Input the parameters;
Number of moles = 
= 0.69moles

Answer:
NH3 and HCl
Explanation:
NH3 and HCl are acids because of their hydrogen ions. NHO3 and NaOH are bases (you can tell because they have an OH). I don't believe SCl2 is an acid or a base
<span>The bonds in calcium hydroxide, Ca(OH)2, </span> calcium hydroxide, is formed by ionic bonds between Ca2 and OHA. Thank you for posting your question here at brainly. I hope the answer will help you. Feel free to ask more questions here.
Answer:
Water
Explanation:
This is because it only contains one type of molecule.
Answer:
synthesis
Explanation:
The reaction given is a synthesis reaction or combination reaction.
Given equation:
NH₃ + HCl → NH₄Cl
In a synthesis reaction, a single product is formed from two or more reactants
A + B → C
The formation of compounds from the union of constituent elements also falls into this category.
So the given reaction is a synthesis reaction.
In a decomposition reaction two or more products are formed from a single reactant
In a single replacement reaction, one substance replaces another.
In double replacement reactions partners in a chemical specie are exchanged.
Therefore the given reaction is a synthesis reaction
