Point f because that is when it starts going down
Where is the chooses for you question
Correct Answer: option C: Formation of sea ice
Reason:
<span> In cold regions, changes in salinity alters the water present in ocean. Further, water density also changes with temperature. In general, water density in ocean water increases with decreasing temperature. This is because, when salt is ejected into the ocean as sea ice forms, the water's salinity increases. Since, salt water is heavier, the density of the water increases.</span>
The Rock Cycle<span> is a group of changes. Igneous </span>rock<span> can change into sedimentary </span>rock<span> or into metamorphic </span>rock<span>. Sedimentary </span>rock<span> can change into metamorphic </span>rock<span> or into igneous </span>rock<span>. Metamorphic </span>rock<span> can change into an igneous or sedimentary </span>rock<span>. Igneous </span>rock<span> forms when magma cools and makes crystals.</span>
To determine the empirical formula of the compound, we assume a basis of 100 g of this compound. We calculate as follows:
C = 68.75 g
H = 10.90 g
O = 20.35 g
We convert these mass to moles,
C = 68.75 g / 12.01 g/mol = 5.72 mol
H = 10.90 g / 1.01 g/mol = 10.79 mol
O = 20.35 g / 16 g/mol = 1.27 mol
C = 5.72 mol / 1.27 mol = 5
H = 10.79 mol / 1.27 mol = 8
O = 1.27 mol / 1.27 mol = 1
