Title: A 940mL NaCl solution is diluted to a volume of 1.50L and a concentration of 8.00M . What was the in Post by: kwoods30 on Nov 24, 2013 A 940mL NaCl solution is diluted to a volume of 1.50L and a concentration of 8.00M . What was the initial concentration? Express the molar concentration numerically.
Write an equilibrium expression for each of the following chemical equations. 2NO2(g)⇌N2O4(g) Use A for [NO2], B for [N2O4]. 2BrNO(g)⇌2NO(g)+Br2(g) Use A for [BrNO], B for [NO], C for [Br2]. H2O(g)+CO(g)⇌H2(g)+CO2(g) Use A for [H2O], B for [CO], C for [H2], D for [CO2]. CH4(g)+2H2S(g)⇌CS2(g)+4H2(g) Use A for [CH4], B for [H2S], C for [CS2], D for [H2].

Quote IA 940mL NaCl solution is diluted to a volume of 1.50L and a concentration of 8.00M . What was the initial concentration? Express the molar concentration numerically. M1V1 = M2V2.94X = 1.5*8 .94X = 12 X = 12.77M Quote 2NO2(g)⇌N2O4(g) .Use A for [NO2], B for [N2O4] Keq = [B ]/[A]^2 Quote 2BrNO(g)⇌2NO(g)+Br2(g) Keq = [C]*[B ]^2/[A]^2Use A for [BrNO], B for [NO], C for [Br2]. Quote H2O(g)+CO(g)⇌H2(g)+CO2(g) Keq = [C]*[D]/([A]*[B ])Use A for [H2O], B for [CO], C for [H2], D for [CO2]. Quote CH4(g)+2H2S(g)⇌CS2(g)+4H2(g) Keq = [D]^4*[C]/([A]*[B ]^2)Use A for [CH4], B for [H2S], C for [CS2], D for [H2]. Hope this helps, Laser |
