C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat
Explanation:
When Sean cook meals with propane he use a combustion reaction:
C₃H₈ + 5 O₂ → 3 CO₂ + 4 H₂O + heat
When propane (C₃H₈) is reacted with oxygen (O₂) produces carbon dioxide (CO₂), water (H₂O) and heat.

Answer:
pH = 1.6
Explanation:
0 mL NaOH:
⇒ [ H3O+] = M HBr = 0.1 M
⇒pH = -log [H3O+] = 1
30 mL NaOH:
⇒ mol NaOH = 0.1 mol / L * 0.03 L = 3 E-3 mol
⇒ mol HBr = 0.05 L * 0.1 mol/L = 5 E-3 mol
⇒ M HBr = ( 5 E-3 mol - 3 E-3 mol) / 0.08 L = 0.025 M
⇒ pH = - log (0.025) = 1.6
Answer:
In addition to mathematics, physics and astronomy, Newton also had an interest in alchemy, mysticism, and theology.
