Zinc protects iron because it is more reactive than iron and therefore reacts preferentially with any reagent, for instance oxygen:2Zn + O2 --> 2ZnO
This is called sacrificial protection. If the zinc is completely covering the iron it also protects it physically as there is a coherent layer of zinc oxide on the surface which keeps the metals away from attacking reagents.
If you put clean aluminium into copper nitrate solution you get a displacement reaction:
2Al + 3Cu(NO3)2 --> 2Al(NO3)3 + 3Cu

Can I have answer key for chapter 8 review chemical equations 13th edition?
Convet the following word equation into a balanced chemical equation : aluminum metal+ copper (11) fluoride ------> aluminium fluoride + copper metal
What are some equations that are not balancing?
all equations balance as the theory of conservation of mass states that no mass should be lost, so all equations should balance
What is the balanced equation for aluminium reacting with iodine to give solid aluminium iodine?
2Al + 3I2 -> 2AlI3
How Chemical equations are balanced by changing the subscripts of the molecule true or false?
False. They are balanced by changing the coefficients.
What is the balanced equation for aluminum resulting in aluminum iodide?
Aluminium + Iodine ----> Aluminium iodide2 Al + 3 I2 ----> 2 AlI3
which of the following equations is balanced?
2na+s-2nas

Which of the following chemical equations is balanced SiO2 C - Si 2 CO?
2SiO2+2C-->Si2+4CO
What is a good resource for practicing net ionic equations for AP chemistry?
A really good link below has amazing net ionic equations, balanced too! Sorted by type of reaction, really useful. Also try Chemfiesta.com
Is chemical equations required to be balanced?
Yes, chemical equations must be balanced due to the law of conservation of matter/mass.
Chemical equations must be?
balanced.
Equations show each side is equal as far as the number of atoms and molecules?
this is called having a balanced equation .....if both sides are not balanced u must correct it by changing the number of moles
What is the science definition of equilibrium?
Equilibrium word is used in both Physics and Chemistry. In Physics it means substance which are balanced and not falling down or anywhere else then the substance is known as to be in Equilibrium State. In Chemistry it means balancing of two Chemical Equations.
What do balanced equations describe?
Mole Ratios
What is the balanced equation for aluminium reacting with iodine to give solid aluminium iodine?
2Al + 3I2 -> 2AlI3
What des a chemical equation stand for?
chemical equations are used to find out how chemical compounds will react with each other since the equations must be balanced. unless you are talking about the chemical name for substances such as sodium chloride is NaCl. water is H2O etc.
