Actually it pretty much still is saturated with salt at the boiling point, which is just a tad over 100C. That's because the solubility curve for NaCl isn't much of curve. It's more of a nearly horizontal line.
Nonetheless, the solubility curve for NaCl does drift upward slightly as T increases, and so by the time the boiling point is reached, it won't be saturated.
Answer:
152.4 g of O₂ are consumed.
Explanation:
We start from the combustion reaction:
C₃H₈ + 5O₂ → 3CO₂ + 4H₂O
We convert the mass of propane to moles:
41.9 g . 1mol /44g = 0.952 moles
Ratio is 1:5. 1 mol of propane consumes 5 moles of oxygen at propane combustion
Then, 0.952 moles may consume (0.952 . 5) /1 = 4.76 moles.
We convert moles to mass → 4.76 mol . 32g/mol = 152.4 g
A glucose molecule is completely broken down to carbon dioxide and water in glycolysis and the citric acid cycle, but together these two<span> processes yield only a few molecules of ATP.</span>
We have been given the condition that carbon makes up 35%
of the mass of the substance and the rest is made up of oxygen. With this, it
can be concluded that 65% of the substance is made up of oxygen. If we let x be
the mass of oxygen in the substance, the operation that would best represent
the scenario is,
<span> x = (0.65)(5.5 g)</span>
<span> <em> </em><span><em>x =
3.575 g</em></span></span>
