When the balanced equation for this reaction is:

            2SO3 → 2SO2 + O2 so, by using ICE table:

initial    0.391              0          0.125m

change  -X               +2X           +X

Equ     (0.391-X)         2X           0.125+X

when Keq = concentration of products / concentration of reactants

so, by substitution

    4.34  = [2X]^2 * [0.125+X] / [0.391-X]^2  by solving for X

∴ X = 0.357 m 

∴ the concentration of SO2 = 2x = 2 * 0.357 

                                               = 0.714 m

How molecules of N2 gas can be present in a 2.5 L flask at 50°C and 650 mmHg?
ratelena [41]

Answer:

0.482 ×10²³ molecules

Explanation:

Given data:

Volume of gas = 2.5 L

Temperature of gas = 50°C (50+273 = 323 k)

Pressure of gas = 650 mmHg (650/760 =0.86 atm)

Molecules of N₂= ?

Solution:

PV= nRT

n = PV/RT

n = 0.86 atm × 2.5 L /0.0821 atm. mol⁻¹. k⁻¹. L × 323 k

n = 2.15 atm. L /26.52 atm. mol⁻¹.L

n = 0.08 mol

Number of moles of N₂ are 0.08 mol.

Number of molecules:

one mole = 6.022 ×10²³ molecules

0.08×6.022 ×10²³ = 0.482 ×10²³ molecules

How do you convert kilograms to pounds?
Maru [420]

Answer:  (1 Kilogram = 2.20462 pounds) . There are 2.2046226218 lb in 1 kilogram. To convert kilograms to pounds, multiply your figure by 2.205 for an approximate result. 1 kilogram is also equal to 2 lb and 3.27396195 oz. Working out a rough estimate in your head for converting to pounds and ounces may be tricky - remember that there are 16 ounces in a pound.
