- 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:
A. Students made a measurement error, because ending with more products is impossible.
Explanation:
The law of conversation of matter tells us that in a chemical reaction, matter is never created or destroyed, it's simply converted from one form to another. So the mass of reactants should always equal the mass of the products in a chemical reaction. If there is excess mass in the product, the students have made an error of some kind.
I believe the answer is 18.
