The balanced net ionic equation for the neutralization reaction involving equal molar amounts of hno3 and koh is ________.
frosja888 [35]
 The  net ionic  equation for  the neutralization  reaction involving  equal molar amount amount of  HNo3  and KoH  is 

H^+   +  OH^-  =  H2O (l)

    explanation
write  the   chemical equation
HNO3 (aq) + KOH(aq) =  KNO3(aq) +H2O  (l)

ionic   eequation

H^+(aq)  +  NO3^- (aq) +  K^+9aq)   OH^-(aq) = K^+ (aq) + NO3^-(aq)  + H2O(l)


cancel the  spectator  ions( ions which  does  not  take  place in  equation ) for this case    is  NO3^-  and  No3^-

thus the  net ionic  is


H^+(aq)  + OH^- (aq)  =  H2O(l)

7. A solution contains a mixture of pentane and hexane at room temperature. The solution has a vapor pressure of 250 torr . Pure
Sliva [168]

Answer:

mole fraction hexane 0.64

Explanation:

We know from Raoult's law of partial pressures that for a binary mixture, the vapor pressure above solution is the sum of the partial pressures of each gas:

P total = P(A) + P(B)

Also the partial pressure of a component is the product of its mole fraction , X, times its pure vapor pressure:

Ptotal = X (A)Pº(A) + X (B)Pº(B)

Since for solution of two components the mole fractions add to one, we now have all the information required to compute the answer.

250 torr = X(hexane)151 torr + ( 1 - X(hexane) )425 torr

250 = 151X(hexane) + 425 - 425 X(hexane)

274 X(hexane) = 175

X(hexane) = 1 -0.6 = 0.64
