Sodium chloride is made up of clear, colorless crystals. s solution of sodium chloride in water is s good conductor of electricity. which statement describes sodium chlorideit is made up of ions that are held together by ionic bonds. it is made up of atoms that are held together by metalic bonds. itis made up of atoms that are held together by covalent bonds woth equal sharing electrons. it is made up of atoms that are held together by covalent bonds with unequal sharing of electrons.

your answer is a hope this helps

Option (a) is the correct answer.

Explanation:

A compound formed by sharing of electrons is known as a covalent compound. Whereas a compound formed by donating electrons is known as ionic bond.

Also, it is known that an ionic or polar compound is soluble in polar solvent like water. And a non-polar compound is soluble in a non-polar solvent.

For example, sodium has 11 electrons and chlorine has 17 electrons. So sodium will donate one extra electron to chlorine in order to complete their octet. Hence, it will result in the formation of an ionic compound.

Thus, we can conclude that the statement it is made up of ions that are held together by ionic bonds, is true.

number of molecules / avogadro's number * molecule molecular = mass

explanation:

we define a gram-molecular weight as the mass of one mole of any element or compound. a mole contains avogadro's number of units (molecules) –  

6.022

x

10

23

. so, dividing the number of molecules by avogadro's number gives us the number of moles. multiplying that by the molecular weight gives us the mass. from the periodic table we find the gram-molecular weight of u to be238 and of f to be19. so,  

u

f

will have a gram-molecular weight of 352g.
