Only in case if there are impurities are present in other sample of that substance.
Answer:
1.95mol
Explanation:
First let us generate the equation for the reaction:
2H2 + O2 —> 2H2O
From the equation,
1mole of O2 reacted to produce 2moles of H2O.
Therefore, Xmol of O2 will react to produce 3.9 mol of H2O i.e
Xmol of O2 = 3.9/2 = 1.95mol
The correct option in here is the first one: <span>pentane-1,5-diamine. This is also known as cadaverine. This is a common compund that produces that unpleasant odor from the fish. </span>
The correct answer for the question that is being presented above is this one: "C. solubility level." The <span>term defines the amount that a solute can dissolve into a solution is called the solubility level. The higher the solubility level, the faster it dissolves.</span>
