Be sure to answer all parts. Enter your answers in scientific notation. The following reactions have the indicated equilibrium c

onstants at a particular temperature:
N2(g) + O2(g) ⇌ 2NO(g) Kc = 4.3 × 10−25 2
NO(g) + O2(g) ⇌ 2NO2(g) Kc = 6.4 × 109

Determine the values of the equilibrium constants for the following equations at the same temperature:
(a) 4NO(g) ⇌ N2(g) + 2NO2(g) × 10
(b) 4NO2(g) ⇌ 2N2(g) + 4O2(g) × 10
(c) 2NO(g) + 2NO2(g) ⇌ 3O2(g) + 2N2(g) × 10

The speed of light in a vacuum is 2.998 × 10 8 8 m/s. How long does it take for light to circumnavigate the Earth, which has a c
castortr0y [3046]

Answer:- 0.134 seconds

Solution:- The speed is given as 2.988*10^8\frac{m}{s} and the circumference is 24900 miles which is same as the distance light have to covered. It asks to calculate the time required to cover this distance by the light.

Unit conversion is needed from miles to meters since the speed is given in meters per second.

1 mile = 1609.34 meters

Thus, 24900mile(\frac{1609.34meter}{mile})

= 40072566 meters

Now, speed=\frac{distance}{time}

Rearranged for time, that gives: time=\frac{distance}{speed}

Inserting the values:

time=\frac{40072566meter}{2.988*10^8\frac{meter}{second}}

= 0.134 seconds

Hence, light would take 0.134 seconds to traverse the indicated distance. The answer without the unit is 0.134.

How many micrograms of iron were in the 8.0 mL sample of Greg's blood?
castortr0y [3046]
The result is: 3.36 micrograms of iron in<span> Greg's blood sample.
</span>m(Fe) = 42 mcg(micrograms).
V(Fe) = 1 dL = 1 dL · 100 mL/1dL.
V(Fe) = 100 mL.
Using proportions: m(Fe): 8 mL = 42 mcg: 100 mL.
Thus, 100 mL · m(Fe) = 8 mL · 42 mcg.
m(Fe) = 336 mL·mcg ÷ 100 mL.
m(Fe) = 3.36 mcg.

The boiling point of another member of this homologous series was found to be 309 KK. What is the likely molecular formula for t
KiRa [2933]

Answer: Pentane C5H12

Explanation:

The boiling point is defined as the temperature at which a liquid's vapor pressure matches the external pressure, causing the liquid to turn into vapor.

This compound is likely Pentane, represented as C5H12, since its boiling point falls between that of Butane, with the formula C4H10, and Hexane, with the formula C6H14.
