Answer:
Don't get me wrong the seas are, by distant, the biggest store of water on soil, over 96% of all of Earth's water exists within the seas. Not as it were do the seas give dissipated water to the water cycle, they moreover permit water to move all around the globe as sea streams. I mean, that's all i know man, give me a break.

Answer:
The mass of oxygen gas required to produce 65.75 grams of steam is approximately 162.2 grams
Explanation:
From the question, we have the following chemical reaction equation;
2C₃H₁₈(l) + 25O₂ (g) → 16CO₂(g) + 18H₂O (g)
The molar mass of oxygen, O₂ = 32 g/mol
The molar mass of steam, H₂O = 18.01528 g/mol
25 moles of oxygen are required to produce 18 moles of steam
Therefore, according to Proust's law of definite proportions;
(32 × 25) g of oxygen are required to produce (18 × 18.01528) g of steam
65.75 g of steam will be produced by (32 × 25)/(18 × 18.01528) × 65.75 g ≈ 162.2 g of oxygen O₂.
Answer:
Proxima Centuri is 9 orders of magnitude further from New York compared to Perth
Explanation:
Distance of Proxima Centuri to New York = 4 × 10^16 meters
Distance of Proxima Centuri to Perth = 11000 miles
Since 1 mile = 1609 meters, distance to Perth in meters = 11000 × 1609
Distance to Perth = 17699000 = 1.7699 × 10^7 meters
Order of magnitude of the distances of Proxima Centuri to New York and Perth = 10^16/10^7
Order of magnitude = 10^9
Therefore, Proxima Centuri is 9 orders of magnitude further from New York compared to Perth.
