Which formula represents a molecule having a nonpolar covalent bond?.
1 answer:
The formula which represents a molecule having a non-polar covalent bond is: ethane ().
A covalent bond can be defined as a bond that typically involves the sharing of electrons between the atoms of a non-metallic chemical element.
In Chemistry, the two (2) main types of covalent bond include:
- Polar covalent bond
- Non-polar covalent bond
A non-polar covalent bond is a type of covalent bond that is formed when bonding electrons are <u>shared equally</u> between two (2) atoms. Thus, bonding electrons are <u>shared equally</u> in non-polar covalent bonds.
In conclusion, the formula which represents a molecule that has a non-polar covalent bond is ethane () because the hydrogen atoms are <u>shared equally</u> between the two (2) carbon atoms, as shown in the image attached below.

Complete question;
<em>The distribution of lengths of salmon from a certain river is approximately normal with a standard deviation of 3.5 inches. If 10 percent of salmon are longer than 30 inches, which of the following is closest to the mean of the distribution? 26 inches A 28 inches B 30 inches C 33 inches D 34 inches</em>
Option B is correct. The value that is closest to the mean of the distribution is 30inches.
The formula for calculating the z-score is expressed as:
Given the following parameters
If 10 percent of salmon are longer than 30 inches, then:
- P(x>30) = 0.1
Using the z table to get the value corresponding to the mean area 0.1.
- The required z-score will be -1.285
Substitute the resulting parameters into the formula to get the mean of the distribution.
Hence the value that is closest to the mean of the distribution is 30inches.
