<u>Answer:</u> The given number is equal to -9.0606\times 10^{5}

<u>Explanation:</u>

Scientific notation is defined as the notation in which a number is expressed in the decimal form. This means that the number is always written in the power of 10 form. The numerical digit lies between 0.1.... to 9.9.....

If the decimal is shifting to right side, the power of 10 is negative and if the decimal is shifting to left side, the power of 10 is positive.

We are given:

A quantity having a value of -906,060

Converting this into scientific notation, we get:

\Rightarrow -906,060=-9.0606\times 10^{5}

As, the decimal point is shifting to left side, thus the power of 10 is positive.

Hence, the given number is equal to -9.0606\times 10^{5}

<u>Answer:</u> The equilibrium constant for the reaction is 54.47

<u>Explanation:</u>

The equilibrium constant is defined as the ratio of the concentration of products to the concentration of reactants raised to the power of the stoichiometric coefficient of each. It is represented by the term K_{eq}

The given chemical equation follows:

H_2+I_2\rightleftharpoons 2HI

The expression for equilibrium constant will be:

K_{eq}=\frac{[HI]^2}{[H_2][I_2]}

We are given:

[HI]_{eq}=1.3544\times 10^{-2}M

[H_2]_{eq}=4.5647\times 10^{-3}M

[I_2]_{eq}=7.378\times 10^{-4}M

Putting values in above expression, we get:

K_{eq}=\frac{(1.3544\times 10^{-2})^2}{(4.5647\times 10^{-3})(7.378\times 10^{-4})}\\\\K_{eq}=54.47

Hence, the equilibrium constant for the reaction is 54.47

Suppose you are titrating vinegar, which is an acetic acid solution of unknown strength, with a sodium hydroxide solution accord
OleMash [197]

Answer:

0.0626 M

Explanation:

Equation of the reaction

CH3COOH(aq) + NaOH(aq) ---------> CH3COONa(aq) + H2O

Concentration of acid CA= ???

Concentration of base CB= 0.1943 M

Volume of acid VA= 10.0ml

Volume of base VB= 32.22 ml

Number of moles of acid NA= 1

Number of moles of base NB= 1

From

CA= CB VB NA/VA NB

Hence ;

CA= 0.1943 M × 32.22 ml × 1/10.0ml ×1

CA= 0.0626 M
