What pH is needed to produce this value of Q if the concentration and pressure values are [Br2]=2.50×10?4M, [Br?]=11.85M, [SO42?

Bingel [31]

Explanation:

The given reaction will be as follows.

$2H_{2}O + Br_{2} + SO_{2} \rightarrow 2Br^{-} + SO^{2-}_{4} + 4H^{+}$

Hence, expression that represents relation between given reaction and Q will be as follows.

Q = $\frac{[Br^{-}]^{2}[SO^{2-}_{4}][H^{+}]^{4}}{[Br_{2}]P_{SO_{4}}}$

$1.4 \times 10^{-26}$ = $\frac{(11.85)^{2} \times (8.35) \times [H^{+}]^{4}}{(2.5 \times 10^{4}) \times 2.50 \times 10^{5}}$

$[H^{+}]^{4} = 7.46 \times 10^{-34}$

$[H^{+}]= 5.22 \times 10^{-10}$

As relation between pH and $[H^{+}]$ is as follows.

pH = -log $[H^{+}]$

= -log $5.22 \times 10^{-10}$

= -(0.717 - 10)

= 9.28

Thus, we can conclude that the pH needed to produce the given value of Q is 9.28.

2. How much energy must be removed from a 50.0 g sample of steam in order to get it to condense

Strike441 [17]

Answer:

113 kJ or 113,000J

Explanation:

Since we are condensing it, a physical change in the state of matter is occurring. 113 kJ or 113,000J because of the following equation: Q = 2260 times 50. 2260 is the Heat of Vaporization constant.

The normal boiling point of cyclohexane is 81.0. What is the vapor pressure of cyclohexane at 81.1

snow_lady [41]

Answer:

1 atm

Explanation:

The normal boiling point of a liquid is temperature at which the vapour pressure of the liquid equals 1 atm.

If the normal boiling point of cyclohexane is 81.0 °C, the vapour pressure of the liquid is 1 atm.

The graph below shows that the vapour pressure of cyclohexane reaches 1 atm at about 81 °C.

If the coefficient 2 is placed in front of the product tetraiodine nonaoxide (I4O9), then, how many atoms of each element must b

gogolik [260]

Answer:

Number of iodine atoms = 2 × 4 = 8

Number of oxygen atoms = 2 × 9 = 18

Explanation:

Coefficient 2 is placed in front of the product tetraiodine nonaoxide:

= $2I_4O_9$

Number of iodine atom in a single molecule tetraiodine nonaoxide = 4

Number of oxygen atoms in a single molecule tetraiodine nonaoxide = 9

Coefficient 2 is placed in front of the product tetraiodine nonaoxide:

= $2I_4O_9$

Number of iodine atoms = 2 × 4 = 8

Number of oxygen atoms = 2 × 9 = 18
