The complete balanced equation for the reaction between barium hydroxide and acetic<br> acid is

TiliK225 [7]

Answer:

2 CH3COOH + Ba(OH)2 --> Ba(C2H3O2)2 + 2H2O

To make it less clustered, you can use Ac for C2H3O2.

2 HAc + Ba(OH)2 --> Ba(Ac)2 + 2H2O

The acetic acid reacts with the base barium hydroxide to form the salt barium acetate and water.

Be sure to answer all parts. an aqueous solution of a strong base has a ph of 10. 220 at 25°c. calculate the concentration of th

tia_tia [17]

An aqueous solution of a strong base has a pH of 10. 220 at 25°C then concentration of the base if the base is

(a) LiOH = 1.66× $10^{-4}$ M

(b) $Ba(OH)_{2$ = 3.32× $10^{-4}$ M

Calculation ,

For calculation of concentration of the LiOH and $Ba(OH)_{2$ first we have to calculate pOH of the solution.

pH + pOH = 14

pOH = 14 - pOH = 14 - 10.22 = 3.78

pOH = -㏒ [ $OH^{-}$ ]

[ $OH^{-}$ ] = $10^{-pH}$ = $10^{-3.78}$ = 1.66× $10^{-4}$

So , concentration of the base LiOH = 1.66× $10^{-4}$

So , concentration of the base $Ba(OH)_{2$ = 1.66× $10^{-4}$ ×2 = 3.32× $10^{-4}$

Calculate the approximate enthalpy of the reaction in joules. Estimate that 1.0 mL of vinegar has the same thermal mass as 1.0 m

Nesterboy [21]

Explanation:

The given data is as follows.

Density of vinegar = 1.0 g/ml

Specific heat capacity = 4.25 $J/g ^{o}C$

$T_{1}$ = $17 ^{o}C$ , and $T_{2}$ = $14 ^{o}C$

Relation between enthalpy and specific heat is as follows.

$\Delta H = mC \Delta T$

Hence, putting the values into the above formula as follows.

$\Delta H = mC \Delta T$

= $25 \times 1.0 \times 4.25 J/g ^{o}C \times -3^{o}C$ (as density = $\frac{mass}{volume}$ )

= - 315 J

Thus, we can conclude that the enthalpy of reaction is -315 J.

As the value is negative so, it means that heat is releasing. Hence, the reaction is exothermic in nature.
