Answer:polar covalent bond
Explanation:
Compounds are formed ether by donating, receiving or sharing of electrons making the bonds between them to be ionic, or covalent .
Now according to the rule of type of bond assignment due to electronegativity difference of atoms
---When the electronegativity difference is less than 0.5, the bond formed is nonpolar covalent.
---When the electronegativity difference is between 0.5 and 1.6, the bond is considered polar covalent
---When the electronegativity difference greater than 2.0, then the bond is ionic.
Therefore, When the absolute value of the difference in electronegativity of two adjacent atom in a compound is 1, they are most likely bonded by polar covalent bond eg HCl bond , CCL4 bond
Answer:
Explanation:
Hello!
In this case, since the sulfuric acid and sodium hydroxide react in a 1:2 mole ratio, given the reaction, we realize they have the following mole ratio at the equivalence point:
Which in terms of concentrations and volumes is:
Thus, we can plug in the volume and concentration of acid to find the moles of base:
Best regards!
