What is the majority of 0.50 g of na dissolved in a 1.5 L solution

Answers

The correct answer is 0.014467 M.  

Molarity is defined as the number of moles present in a liter solution, that is, number of moles / liter solution.  

The molar mass of sodium (Na) is 23.0 g/mol

Thus, 1 mole of Na contains 23.0 g

Now, x moles of Na contains 0.50 g

Moles = 0.50 × 1 / 23.0

Moles = 0.50 / 23.0  

= 0.0217 moles of Na

Molarity = Number of moles / liters of solution

= 0.0217 / 1.5

= 0.014467 M

What factor distinguishes a metallic bond from an ionic bond or a covalent bond

Answers

Answer:

The ionic bond occurs between two different atoms (metal and nonmetal), while the covalent bond occurs between two equal atoms (nonmetals),

Another difference between these is that the covalent bond is an electron compartment, while in the ionic bond there is an electron transfer.

Metal bonding occurs when metals are combined with each other. Metal atoms need to give up electrons to reach the configuration of a noble gas. In this case, the metals lose the valence electrons and an electron cloud forms between the positive nuclei.

The answer to this question is:

The mobility of electrons.
