<em>K</em>_eq = 0.14
The chemical equation is
A ⇌ B
The equilibrium constant expression is
<em>K</em>_eq = [B]/[A]
If [A] = 7[B]
<em>K</em>_eq = [B]/{7[B]}= 1/7 = 0.14
Answer:
<h2>6.41 %</h2>
Explanation:
The percentage error of a certain measurement can be found by using the formula

From the question
actual density = 7.80 g/cm³
error = 7.30 - 7.80 = 0.5
We have

We have the final answer as
<h3>6.41 %</h3>
Hope this helps you
Answer:
The diversity of physical properties among covalent compounds is mainly because of widely varying intermolecular attractions. ... All of the atoms are covalently bonded to each other.
Answer:
0.055g/mL
Explanation:
Data obtained from the question include:
Molar Mass of the gass sample = 71g/mol
Volume of the gas sample = 1300 mL
Density =?
The density of a substance is simply mass per unit volume. It is represented mathematically as:
Density = Mass /volume.
With the above equation, we can easily obtain the density of sample of gas as illustrated below:
Density = 71g / 1300 mL
Density = 0.055g/mL
Therefore, the density of the gas sample is 0.055g/mL
CBr4 is a symmetric tetrahedral molecule so it will be non-polar.
