What is the correct balanced equation for the following equilibrium constant expression?

Chemistry
1 answer:
weeeeeb [17]4 years ago
8 0
The correct answer is 3) 2CO2(g) ⇄ 2CO(g)  + O2(g)

this is the correct one because it is a decomposition reaction and all the number of atoms is equal on both sides.

there are 2 C atoms on both sides. 

and 4 O atoms on both sides.

and 1) the atoms numbers are equal on both sides but not correct as it not a

correct number as it has 1/2 O2.


and 2) CO2(g) ⇆ CO(g) + O2 

the number of O atoms is not equal on both sides of the equation.

we have 2 O atoms on the left side and 3 O atoms on the right side.

so, this not a balanced equation.

4) also not correct 2CO(g) + O2 ⇆ 2CO2

as it is not a decomposition reaction and the 2CO & O2 are as reactants not products.

so the correct answer is 3) 2CO2(g) ⇆ 2CO(g) + O2(g)

How can the partial charges be shown in a polar covalent molecule?
joja [24]
Δ, namely δ− or δ+. Partial charges<span>are created due to the asymmetric distribution of electrons in chemical bonds. For example, in a </span>polar covalent<span> bond like HCl, the shared electron oscillates between the bonded atoms.</span>

(b) What is the pOH of 1.35x10⁻³ M HCl? Is the solution neutral, acidic, or basic?
nika2105 [10]

The pOH scale is similar to the pH scale in that a pOH of 7 is indicative of a neutral solution. A basic solution has a pOH less than 7, while an acidic solution has a pOH of greater than 7

<h3>What is pOH scale?</h3>

Based on the relative concentration of hydrogen and hydroxyl ions, the pH and pOH scales are used primarily in chemistry, biology, and soil science to describe and measure the acidity and basicity of neutral, acidic, and basic solutions in water.

The terms pH and pOH scale are frequently used and crucial for determining the chemical, biological, and soil health by converting the values of hydrogen or hydroxyl ion concentrations or by utilizing pH paper and meters.

The pH scale or chart, which measures the concentration of hydrogen and hydroxyl ions in acidic and alkaline solutions, was initially developed by Sorensen.

2 years ago a 4.00 l flexible container holds a sample of hydrogen gas at 153 kpa. if the pressure increases to 203 kpa and the
garri49 [273]

To solve this we assume that the gas is an ideal gas. Then, we can use the ideal gas equation which is expressed as PV = nRT. At a constant temperature and number of moles of the gas the product of PV is equal to some constant. At another set of condition of temperature, the constant is still the same. Calculations are as follows:

 

P1V1 =P2V2

 V2 = P1 x V1 / P2

 <span>V2 = 153 x 4 / 203</span>

 V2 = 3 L
