Answer:
NaCl
Explanation:
HCI is a poiar covalent compound while ℂI4 is a non-polar covalent compound because both are iormed by sharing of electrons. KCl and NaCl are formed by the transfer of electrons and are ionic compounds.
go to periodic table
look for the element you want
find the atomic number on the top right hand side of the element
atomic number = equal to number of proton.
find atomic mass bottom right hand side of the element
atomic mass - atomic number = neutron
i hope this will help
Na atomic number 11 and mass number 23
protons 11
neutron =23-11=12
Answer:
moles = no. of molecules / Avogadro's number
= 2.26 x 10^33 / 6.022 x 10^23
= 3752906011
Round to significant figures which is 3 = 3.75 x 10^9 mol
Explanation: The formula for finding how many moles of a substance when given the amount of molecules is: moles = number of molecules / Avogadro's number
