Enter your answer as a number. 3 Zn(s) + 2 Al3+(aq) ⟶⟶ 2 Al(s) + 3 Zn2+(aq) 6 find LCM Identify the oxidizing agent in the redox reaction: 3 Zn(s) + 2 Al3+(aq) ⟶⟶ 2 Al(s) + 3 Zn2+(aq) Al3+(aq) Zn(s) Al(s) Zn2+(aq) Al3+(aq)

Of the following substances, _____ has the HIGHEST normal boiling point. a) HCl b) CH2Cl2 c) CH3Cl d) NaClNaCl What is the expression for the equilibrium constant? N2(g)+3H2(g)⇔2NH3(g)Keq=[NH3]2/[N2][H2]3 Solubilities of several ionic compounds in water as a function of temperature. Which of the following has the highest solubility (expressed as g of salt in 100 g of water) at 20°C? a) Potassium chloride b) Cerium sulfate c) Sodium nitrate d) Potassium nitrateSodium nitrate

buffer A solution with a significant amount of weak acid mixed with its conjugate base a buffer solution resists... pH change is the solution still considered a buffer if the acid or base is strong generally no a buffer normally consists of a weak acid and its conjugate base what does a weak acid in a buffer do neutralize added base what does the conjugate base of a weak acid do in a buffer neutralize added acid how do buffers minimize pH change when a strong acid is added -the prot...

Bronsted acid a proton donor Bronsted base proton accepter When can a substance act as an acid? only when a base is present deprotonated when am acid loses its H+ (proton) rxn with strong acid / base almost all the acids / bases are deprotonated / protonated so the reaction is said to go to completion acid-base equilibrium all acids and bases are at dynamic equilibrium; even the strong ones that are so in favor of the products that they are said to go to completion arrhenius acid forms...
