You have to find the molar mass of Al and O. You can do it!!
Answer:
-0.044 V
Explanation:
The overall electrode potential is usually estimated by subtracting the potential of the reference electrode from the potential of the system in question. In the given problem, the standard electrode potential of silver-silver chloride with respect to the standard hydrogen electrode is +0.197 V. In addition, the potential of the calomel reference electrode with respect to the standard hydrogen electrode is +0.241 V. Using the data above, the potential of with respect to silver-silver chloride is equivalent to 0.197-0.241 = -0.044 V.
The answer is 10%
The percent error is used to determine the precision of calculations. It can be expressed as:

where:
e - the percent error,
v - experimental value (measured value),
v₁ - theoretical value,
It is given:
e = ?
v = 88 calories
v₁ = 80 calories
Thus, the percent error is:
Answer:
No streak of light will appear.
Reason I given below.
Explanation:
No streak of light will be seen.
This is because as it falls to the moon, the gravitational pull plus the dense atmosphere which was necessary to produce friction when it fell to the earth are not present in this case and as such the whole meteor is not burnt like it did when it fell to the earth.
I think it might be A. Supergiants.
