Point A\mathrm{A}A on the string is shown at time t=0t=0t=0. Write abalanced chemical equation showing how, A:(a) Question = Is C2H6Opolar or nonpolar ? H2S Be sure to include the proper phases for all species within the reaction. Identify the following salts as neutral acidic or basic: LiNO3, SrBr2, LiF, KCN, NH4ClO4, NH4Br, NH4CN, LiNO3,- neutral (salt of a strong acid and a strong base) If neutral, simply write only NR. In this section of chemistry, we discuss the pH values of salts based on several conditions. A solution contains 0.675 g of ethylamine, C2H5NH2, per 100.0 mL of solution. NaOH is strong base, HCl a strong acid, solution is neutral First of all, we know a few things: Take for example dissociation of \(\ce{H2CO3}\), carbonic acid.
