What are the symbol equations for these statements below please help me?
1. magnesium + nitric acid = magnesium nitrate + hydrogen
2. zinc + hydrochloric acid = zinc chloride + hydrogen
3. iron + sulphuric acid = iron sulphate + hydrogen
4. copper + sulphuric acid = copper sulphate + hydrogen
i would appreciate symbol equation answers
Answers:
Mg + 2HNO3 -> Mg(NO3)2 +H2^
Zn + 2HCl -> ZnCl2 + H2^
4Fe + 6H2SO4 -> 2Fe2(SO4)3 + 6H2^
Cu + H2SO4 -> CuSO4 + H2^
Remember the numbers in front of the symbols are large those in the middle or at the end of the symbols are small. ^ means given off as a gas.
oh my god you have issues
Whats this, back to school, not on a Sat. night thanks.
If you can't do your own homework you're wasting youur time.
Christop has it right, but you need to add on the H2^ in some of them.
2Mg + 2HNO3 = 2MgNO3 + H2
Just a guess from 1963.
1. Mg (s) + 2HNO3 (aq) --> Mg(NO3)2 (aq) +H2 (g)
2. Zn (s) + 2HCl (aq) --> ZnCl2 (aq) + H2 (g)
3. 2Fe (s) + 3H2SO4 (aq) --> Fe2(SO4)3 (aq) + 3H2 (g)
4. Cannot occur as copper is below hydrogen in the reactivity series.
The main thing to remember is the number of each type of atoms on one side of the equation have to equal the number on the other side. Then you just need to know the valencys of the different elements.
1. Mg + 2HNO3 Mg(NO3)2 +H2
2. Zn + 2HCl ZnCl2 +H2
3. Fe + H2SO4 FeSO4 +H2 (It is Iron (II) sulphate not Iron (III) sulphate as stated in a previous answer which is formed.)
4. Cu + H2SO4 CuSO4 + H2
Don't forget to write (aq) after compunds in aqueous solution and (g) after hydrogen gas etc.
1> Mg +HN03=Mg(NO3)2+H2
2> Zn + 2HCl=ZnCl2+H2
3> Fe +H2SO4=FeSO4+H2
4> Cu +H2SO4=CuSO4+H2
