Question
What mass of Al₂O₃ form is produced if 25.00 g of aluminum (al) is reacted completely?, knowing the molar mass of Al₂O₃ is 102 g/mol?
Atomic mass of Al =27 and O = 16
The molar mass of Al₂O₃ = 102.
Mass of aluminium in 102 g of Al₂O₃ = 54 g
54 g Al => 102 g Al₂O₃
25g Al => x g Al₂O₃
x = 25*102/54 = 47.2 g Al₂O₃

Explanation:
The proton motive force; is the free energy released during the oxidation of NADH or FADH2 and it is stored both as an electric potential and a proton concentration gradient across the inner membrane.
The purpose of proton motive force is that the movement of protons back across the inner membrane, driven by this force, is used to the synthesis of ATP from ADP and Pi by ATPase/ ATP synthase (F0F1 complex ).
Explanation:
This is feasible single displacement chemical reaction. In this reaction, Zinc displaces cadmium from the chlorate solution:
Zn + Cd(ClO₃)₂ → Zn(ClO₃)₂ + Cd
A single displacement reaction is a reaction in which one specie replaces another.
The main driving force in this kind of reaction is the position of the displacing species in the activity series.
In the series, metals that are higher up are more reactive and they will displace the lower ones from solution.
Cadmium is lower in the series and Zn is higher up.
Zn is more reactive than Cd and will displace it form the solution and it gives the expression:
Zn + Cd(ClO₃)₂ → Zn(ClO₃)₂ + Cd

Answer:Sources of lead emissions vary from one area to another. At the national level, major sources of lead in the air are ore and metals processing and piston-engine aircraft operating on leaded aviation fuel. Other sources are waste incinerators, utilities, and lead-acid battery manufacturers. The highest air concentrations of lead are usually found near lead smelters.
