Answer:
pH = 2.7
Explanation:
pH = -log[H^+] for HNO3 pH = - log{HNO3]= -log[1.9*10^-3] = 2.7
Answer:
Electronegativity is the strength an atom has to attract a bonding pair of electrons to itself. When a chlorine atom covalently bonds to another chlorine atom, the shared electron pair is shared equally. The electron density that comprises the covalent bond is located halfway between the two atoms.
