With what are you need help?
Mixtures of sand and water or sand and iron filings, a conglomerate rock, water and oil, a portion salad, trail mix, and concrete (not cement).
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:
Answer is C because in exothermic reactions, energy releases.
in Cellular respiration,
ATP+H20 (water) = ADP+ Pi + Energy
So celullar respiration is exothermic and releases energy
Answer:
9 : 8
Explanation:
Aluminum oxide has the following formula Al₂O₃.
Next, we shall determine the mass of Al and O₂ in Al₂O₃. This can be obtained as follow:
Mass of Al in Al₂O₃ = 2 × 27 = 54 g
Mass of O₂ in Al₂O₃ = 3 × 16 = 48 g
Finally, we shall determine the mass ratio of Al and O₂. This can be obtained as follow:
Mass of Al = 54 g
Mass of O₂ = 48 g
Mass of Al : Mass of O₂ = 54 : 48
Mass of Al : Mass of O₂ = 54 / 48
Mass of Al : Mass of O₂ = 9 / 8
Mass of Al : Mass of O₂ = 9 : 8
Therefore, the mass ratio of Al and O₂ in Al₂O₃ is 9 : 8
