Gas companies often store their fuel supplies in liquid form and in large storage tanks. Liquid nitrogen is used to keep the temperature low enough for the fuel to remain condensed in liquid form. Although continuous cooling is expensive, storing a condensed fuel is more economical than storing the fuel as gas. Suggest a reason that storing a liquid is more economical than storing a gas.
ACIDS AND BASES Acids: produces H+ (which is the same as protons and hydronium ion, H3O+) AND are mostly covalent compounds! H+ + OH- à H2O acid base neutralization The “protics” HCl à H+ Monoprotic ** Compounds that are monoprotic and H2SO 4à 2 H+ Diprotic diprotic are strong acids! H3PO 4à 3 H+ triprotic ** Triprotic are weak acids Ex: H2CO3 à Diprotic weak acid CH 3COOH à monoprotic weak acid Characteristics of acids: Sour Turns blue litmus paper into pink Strong Acids v. Weak acids : 2 converting pH concentration 3 Bases: substances producing OH- in an aqueous solutions AND are ALL ionic compounds Characteristics: Taste is unknown (no one has actuall
