A molecule<span> is an </span>electrically<span> neutral group of two or more </span>atoms<span> held together by </span>chemical bonds<span>. So I would say is all of them, as they all contain two atoms each even in the diatomics </span>
Answer:
C) 3.37 moles
.
Explanation:
Hello,
In this case, considering that the atomic mass of aluminum is 27.0 g/mol, the moles in 90.93 g of aluminum are computed via the following dimensional analysis:
Thus, answer is C) 3.37 moles
.
Best regards.
<span>A. the sum of the protons and neutrons in one atom of the element</span>
I think it would be B <em>"A heterogeneous catalyst is being used in the reaction"
</em>This is because MnO2 is a heterogeneous catalyst as it's in a different state than the rest of the reactants and products.
The MnO2 isn't being used as a reactant so it's a catalyst.
MnO2 is not an enzyme
hope that helps
The correct answer among the choice presented above would be option C. The solution that will have the greatest freezing point depression is <span>11 g of calcium fluoride (CaF2). This is because it has higher concentration among other solutions. Also, when it ionizes 3 ions are formed.</span>
