If an equilibrium mixture contains 0.54 m no2, what is the molar concentration of n2o4?

1 answer:

3 0

<span>From the chemical equ NO2 + 02 gives N2O4 . The above means that 1 mole of No2 produces1 mole of N204. Hence 0.54 mole of NO2 will also produce 0.54 mole of N2O4.</span>

A 50°C solution has a pH of 3.30. At this temperature, Kw = 5.48 x 10 9. What is the pOH of the solution?

sammy [17]

Answer:

9.93

Explanation:

Your value for Kw is incorrect. The correct value is 5.48 × 10^-14.

pH + pOH = pKw

3.30 + pOH = -log(5.84 × 10^-14) = 13.23

pOH = 13.23 - 3.30 = 9.93

The pOH of the solution is 9.93.

Some scientists believe that life on Earth may have originated near deep-ocean vents. Balance the following reactions, which are

goldenfox [79]

Answer :

(1) The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

Explanation :

Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.

If the amount of atoms of each type on the left and right sides of a reaction differs then to balance the equation by adding coefficient in the front of the elements or molecule or compound in the chemical equation.

The coefficient tell us about that how many molecules or atoms present in the chemical equation.

(1) The unbalanced chemical reaction is,

$CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '2' put before the $CH_3SH$ and we get the balanced chemical equation.

The balanced chemical reaction will be,

$2CH_3SH(l)+CO(g)\rightarrow CH_3CO(SCH_3)(l)+H_2S(g)$

(2) The unbalanced chemical reaction is,

$H_2S(g)+CO(g)\rightarrow CH_3CO_2H(g)+S_8(s)$

This reaction is an unbalanced chemical reaction because in this reaction number of hydrogen, sulfur and carbon atoms are not balanced.

In order to balance the chemical equation, the coefficient '8' put before the $H_2S\text{ and }CO$ and the coefficient '4' put before the $CH_3CO_2H$ we get the balanced chemical equation.

The balanced chemical reaction will be,

$8H_2S(g)+8CO(g)\rightarrow 4CH_3CO_2H(g)+S_8(s)$

The medicinal thermometer commonly used in homes can be read to Â±0.1Â°F, whereas those in the doctor's office may be accurate t

andrezito [222]

Answer:

the percent error expected from each of theses person's body:

in homes:

% E = 0.14267 %

in doctor's office:

% E = 0.257 %

Explanation:

° C = ( ° F - 32 ) * (5/9)
% E = ( | true - exp | / true ) * 100
body temp = 38.9 ° C = 102.02 ° F

thermometer used in homes:

⇒ T = 102.02 ° F +/- 0.1 ° F = 102.12 ° F ∧ 101,92 ° F

⇒ T = 102.12 ° F = 38.9555 ° C

⇒ % E = ( | 38.9 - 38.9555 | ) / 38.9 ) * 100 = 0.14267 %

in the doctor's oficce:

⇒ T = 38.9 ° C +/- 0.1 ° C = 39 ° C ∧ 38.8 ° C

⇒ % E = (( | 39 - 38.9 | ) / 38.9 ) * 100 = 0.257 %
