The correct answer is (a) The white salt crystals have a high albedo.
A substance appears white in color because it reflects most of the light falling on it. The term albedo shows that most of the sunlight falling on the particular area are reflected back leaving behind the salt of white color. Badwater Basin in Death valley is the hottest, driest and brightest area. Hence, the valley appears to be white in color because of the salt crystals that reflects back the maximum light falling on it.
Answer:
7.8 moles are needed.
Explanation:
Given data:
Mass of oxygen produced = 125 g
Number of moles of mercury oxide needed = ?
Solution:
Chemical equation;
2HgO → 2Hg + O₂
Number of moles of oxygen:
Number of moles = mass/ molar mass
Number of moles = 125 g/ 32 g/mol
Number of moles = 3.9 mol
Now we will compare the moles of oxygen with mercury oxide.
O₂ : HgO
1 : 2
3.9 : 2×3.9 = 7.8 mol
