Suppose you mix one mole of sulfuric acid (h2so4) with 1 mole of sodium hydroxide(naoh). why does the ph of the solution remain below 7? ( explain so i can get better understanding! )

Technician a says that you should never jump-start a frozen battery. technician b says that a frozen battery can explode, causing injury, when jump-started. who is correct?
