Answer:
oh sorry i cant but i might think the answer is adaptive but if not someone correct me and ill change this response hope that i could help
Explanation:
Explanation:
they have different mass number but same atomic number
Answer:
Yes because magnesium has a more negative reduction potential than aluminum.
Explanation:
The single factor that will determine whether a battery with magnesium as anode and aluminium as cathode will work or not is the respective electrode potentials of the two elements.
Recall that in a battery, oxidation occur at the anode and reduction occurs that the cathode. The reduction potential shows the ease with which a metal is reduced or oxidized. The substance with the most negative reduction potential will function as the anode while the substance with the less negative electrode potential will function as the anode.
The reduction potential of Magnesium is -2.37 V while that of aluminum is -1.66 V. This implies that magnesium must function as the anode and aluminum as the cathode in order to have a spontaneous electrochemical process in the cell.
Sugar dissolving in warm water is an example of physical change.
physical change is doesn't alter the composition or the identity of the substance .
That's mean when you dissolves sugar in water, after a while the object will be the same which mean that the component doesn't change
0.025 mg = 25E-3 g Pb.
<span>mols Pb = grams Pb/atomic mass Pb. </span>
<span>1000 mL H2O x 1.00 g/mL = 1000 g = 1 kg. </span>
<span>molality = mols Pb/kg H2O
