- 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.
The answer is A, you must repeat your experiment to ensure you results are accurate. That is the best way to know for sure and it is what you must do to every experiment.
Answer:
e
Explanation:
the reaction can't move to left because H is positive
Explanation:
for respiration(exchange of gases)
The train cars moves in the same direction when the engine car begins
moving to the left.
<h3>What is Law of magnetism?</h3>
The law of magnetism states that like poles repel and unlike poles attract.
In substances which have magnetic field, they are known to attract each
other.
The engine and train car are highly magnetized which results in them
moving in the same direction when they are in close contact with one
another.
