Formic acid (hco2h) has a dissociation constant of 1.8 x 10^-4 m. the acid dissociates 1: 1. what is the [h+] if 0.35 mole of formic acid is dissolved in 1.0 liter of water?

Fill in the coefficients that will balance the following reaction: a0cr2(so4)3 + a1agno3

Identify the correct mole ratio for each substance. sodium chloride (nacl) na: cl = 1: ammonium nitrate (nhno) h: o = 4:

You are attempting to recrystallize a crude product mixture. you add the appropriate amount of hot solvent and are allowing the solution to slowly cool to room temperature. however, at room temperature no crystals have appeared, which of the following methods should be used to induce crystallization? choose all correct answers. a) place the flask in an ice bath. b) swirl the contents of the flask. c) add a small seed crystal of the desired product. d) scratch the inside of the glassware using a stir rod. it can be multiple choices
