Answer:
The answer to your question is below
Explanation:
See the attachment.
Synthesis ΔH
ΔH = 25 - (-30) = 25 + 30 = 55 kJ Endothermic reaction
Single reaction
ΔH = 30 - 65 = -35 KJ Exothermic reaction
Double reaction
ΔH = 60 - 10 = 50 kJ Endothermic reaction
Answer:Chemicals used in fertilizer and pesticides helps the plants growth and healthier condition. That way more plants can grow.
Explanation:
KE = 1/2 * m * v^2
KE = 1/2 * 130 * 23^2
