Answer:
C when lungs expand they fill with air from the atmosphere
- The charge distribution in a CH₄ molecule is symmetric.
- CH₄ molecules are nonpolar.
<h3>Explanation</h3>
A CH₄ molecule has four C-H bonds. Each of the C-H bonds is weakly polar. However, the molecule has a tetrahedral shape. The shape itself is symmetric.
As a result, charges on the four C-H bonds have a symmetric distribution. They cancel out within the molecule. Overall, the molecule is nonpolar.
Answer:
Strong attraction between ions and the second one High melting points
Explanation:
The distance between a carbon atom and an oxygen atom in the co molecule is 0.63
<h3>What is the distance?</h3>
Distance is the measurement of the farness of two objects from each other.
The distance between the molecules can be calculated by the given formula
Putting the values in the equation
Thus, the distance between a carbon atom and an oxygen atom in the co molecule is 0.63
