An earthquake happens when tectonic plates move against each other. A oceanic and a continental tectonic plates might move against each other. When that happens water is pushed upwards and it creates ripples that then move towards land. It's like throwing a rock in water but a lot bigger. I can't post external links on Brainly but you can find more information about tsunami's on Google
Answer:
Explanation:
<u>1. Molecular chemical equation:</u>
- 2 KClO₃(s) → 2 KCl(s) + 3 O₂(g)
<u>2. Mole ratios:</u>
- 2 mol KClO₃ : 2 mol KCl : 3 mol O₂
<u>3. Number of moles of KClO₃</u>
- Number of moles = mass in grams / molar mass
- Molar mass of KClO₃ = 122.55 g/mol
- Number of moles of KClO₃ = 54.3 g / 122.5 g/mol ≈ 0.44308 mol
<u>3. Number of moles of O₂</u>
As per the theoretical mole ratio 2 mol of KClO₃ produce 3 mol of O₂, then set up a proportion to determine how many moles of O₂ will be produced from 0.44038 mol of KClO₃.
- 3 mol O₂ / 2 mol KClO₃ = x / 0.44038 mol KClO₃
- x = (3 / 2) × 0.44308 mol O₂ = 0.6646 mol O₂
Round to 3 significant figures: 0.665 mol of O₂ ← answer
Max Planck concluded that energy is not continuous and is carried in discontinuous units which he named quanta.
Carbon monoxide is produced in an engine
when incomplete combustion happened. In a combustion engine intake valve, it
combines the fuel and air (nitrogen and oxygen) and when spark plug ignites it
pushes the piston downwards. After that piston will push itself upward and
pushes the air that was generated by the combination of those components in the
exhaust valve. This is a repeated cycle which keeps the engine running. In a
perfect combustion process the air being released are carbon dioxide, water and
nitrogen. But when an incorrect ratio of the combination of fuel and air in the
engine is processed, carbon monoxide is being generated.
