Common Questions and Apex Answers

Q1: What is the difference between physical and chemical changes?

According to Apex answers, physical changes alter the form or appearance of a substance without changing its composition, such as melting or freezing. Chemical changes result in new substances with different properties, like rusting or combustion.

Q2: How do you balance a chemical equation?

Apex solutions emphasize balancing by adjusting coefficients to ensure the number of atoms for each element is equal on both sides of the equation. For example:

Unbalanced: H₂ + O₂ → H₂O
Balanced: 2H₂ + O₂ → 2H₂O

Q3: Explain Newton’s second law of motion.

Newton’s second law states that force equals mass times acceleration (F = ma). Apex answers highlight that increasing force results in greater acceleration, and heavier objects require more force to accelerate at the same rate.
