Explanation:
i think its right im not really sure
Answer:
negative
Explanation:
Entropy is a measure of the "disorder" in a system.
In this reaction, the amount of disorder decreases. This is because one gas molecule (NH₃) has more order than two gas molecules (N₂ and H₂). Therefore, the entropy change should be negative.
Answer: All of them are true
Sound is made when air molecules. Vibrate and move in a wave pattern, so sound moves in waves of compressions and refractions (expansion).
Hope this helps! :)
