One mole of Na2SO4 is 6.022 * 10^(23) molecules. We can divide this into the quantity in the question to find a value of 1.5/6.022 = 0.2491 moles. Rounded to two significant figures and put in scientific notation, we can rewrite this quantity as 2.5 * 10^(-1) moles
Omg I wish I knew this one sorry
Hope you can figure it out
<h2>
Answer:</h2>
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
<h2>
Explanation:</h2>
Chemical bonds are formed by gaining, yielding or sharing electrons to reach stable electronic configurations such as those of noble gases. Electropositive atoms give up electrons to complete the most stable configuration, leaving them with a negative charge defect.
