A reaction mixture initially contains 0.86 atm NO and 0.86 atm SO3. Determine the equilibrium pressure of NO2 if Kp for the reac
dlinn [17]

Explanation:

Reaction equation for this reaction is as follows.

     NO(g) + SO_{3}(g) \rightarrow NO_{2}(g) + SO_{2}(g)

It is given that K_{p} = 0.0118.

According to the ICE table,

              NO(g) + SO_{3}(g) \rightarrow NO_{2}(g) + SO_{2}(g)

Initial:           0.86      0.86               0            0

Change:          -x          -x                 +x           +x

Equilibrium:  0.86 - x   0.86 - x         x           x

Hence, value of K_{p} will be calculated as follows.

           K_{p} = \frac{P_{NO_{2}} \times P_{SO_{3}}}{P_{NO} \times P_{SO_{3}}}

         0.0118 = \frac{x \times x}{(0.86 - x)^{2}}

             x = 0.084 atm

Thus, we can conclude that P_{NO_{2}} is 0.084 atm.

How does a bannana flaot
vesna_86 [32]
A banana floats when put in water because bananas are less dense than water, meaning that things with a higher density naturally push it to the surface.
Root beer floats are a different matter, though ;-)
Hope that helped =)

Calculate the number of grams of 02, produced when 43 grams of potassium chlorate decomposes.
Dafna11 [192]

Mass O2 = = 16.832 g

<h3>Further explanation</h3>

Given

43 grams of potassium chlorate

Required

Mass of O2

Solution

Reaction

2KClO3 ⇒3O2 + 2KCl

Mol KClO3 :

= mass : MW

= 43 g : 122,55 g/mol

= 0.3509

From the equation, mol O2 :

= 3/2 x moles KClO3

= 3/2 x 0.3509

= 0.526

Mass O2 :

= 0.526 x 32 g/mol

= 16.832 g

Which of the following chemical formulas shows an ionic compound?
DochEvi [55]
NaCl or Sodium Chloride is an ionic compound. This is because an ionic compound pertains to a compound that consists of positively and negatively charged ions. In this case, Na (Sodium) has a tendency to lose one electron when it reacts with with other atoms, so the resulting sodium ion contains 11 protons and 10 electrons, thus making it positively charged (Na+), When Chlorine reacts, it usually gains one electron to form an ion called chloride, thus making it negatively charged (Cl-). Since the ions are oppositely charged, they attract.
