As per the question ,

2SO_2(g)+O_2\rightleftharpoons2SO_3(g) (given)

\:  \:  \:  \:  \: \:  \:  \:  \:  \: \:  \:  \:  \:

K_c =   \frac{[SO_3]^2}{[SO_2]^2[O_2]}

\:  \:  \:  \:  \: \:  \:  \:  \:  \: \:  \:  \:  \:

\:  \:  \:  \:  \:  = \frac{ ( 1.9)^2M^2}{(0.6)^2(0.82)M^3}

\:  \:  \:  \:  \: \:  \:  \:  \:  \: \:  \:  \:  \:

\:  \:  \:  \: = 12.229 M^{ - 1} (approximately)

\:  \:  \:  \:  \: \:  \:  \:  \:  \: \:  \:  \:  \:

Hence , K for the equilibrium is 12.229M^{-1}

A gaseous fuel mixture stored at 747 mmHg and 298 K contains only methane (CH4) and propane (C3H8). When 11.1 L of this fuel mix
Alisiya [41]

Answer:

M_f=38.8\%

Explanation:

From the question we are told that:

Pressure P=747mmHg

Temperature T=298K

Volume V=11.1

Heat Produced Q=780kJ

Generally the equation for ideal gas is mathematically given by

 PV=nRT

 n= (747/760) *11.1/ (0.0821*298)

 n=0.446mol

Therefore

 x+y=0.446

 x=0.446-y .....1

Since

Heat of combustion of Methane=889 kJ/mol

Heat of combustion of Propane=2220 kJ/mol

Therefore

 x(889) + y(2220) = 760 ...... 2

Comparing Equation 1 and 2 and solving simultaneously

 x=0.446-y .....1

 x(889) + y(2220) = 760 ...... 2

 x=0.173

 y=0.273

Therefore

Mole fraction 0f Methane is mathematically given as

 M_f=\frac{x}{n}*100\%

 M_f=\frac{1.173}{0.446}*100\%

 M_f=38.8\%

In the reaction between the strong acid HCI and the strong base NaOH which of the ions listed below is a spectator ion?
qwelly [4]

Answer:

Na+

Explanation:

The equation would be:

HCl (aq) + NaOH (aq) --> HOH (l) + NaCl (aq)

The equation is already balanced and the NaCl will disassociate in Na+ and Cl- and HCl will disassociate into H+ and Cl- and NaOH will disassociate into Na+ and OH-. Na+ is on both sides of the equation and stays the same, so Na+ will be the spectator ion.

Calculate the volume of 1 M NaOH needed to prepare 10.0 ml of a 0.10 M solution.
Mumz [18]
Answer is: <span>volume of 1 M NaOH is 1 ml.
</span>c₁(NaOH) = 1 M.
V₂(NaOH) = 10 ml.
c₂(NaOH) = 0,1 M.
V₁(NaOH) = ?
c₁ - original concentration of the solution, before it gets diluted.
c₂ - final concentration of the solution, after dilution.
V₁ - <span>volume to be diluted.
V</span>₂ - <span>final volume after dilution.
c</span>₁ · V₁ = c₂ · V₂.
V₁(NaOH) = c₂ · V₂ ÷ c₁.
V₁(NaOH) = 0,1 M · 10 ml ÷ 1 M.
V₁(NaOH) = 1 ml.

Write the symbol for a calcium ion. How many electrons does it have? If the mass number is 41, then how many neutrons does it ha
Fynjy0 [20]

Explanation:

calcium ion is denoted as - Ca ²⁺

The number of electrons in a neutral atom of calcium = 20 , but since ,

it is charged atom ,

i.e. +2 , the number of electrons in calcium ion = 18 .

From , the question ,

The mass number = 41 ,

and

since ,

the mass number = number of protons + number of neutrons .

number of neutrons = mass number - number of protons

since ,

The number of protons for calcium ion = 20

number of neutrons = 41 - 20 = 21

Hence ,

number of neutrons = 21.
