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

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.

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.

a million < 30 < 0.03 2 < 3 <, < i think of the different individual neglected that the middle is 0.5. you will possibly not at all write an equation x < y > z. 4. No, via fact it is not set equivalent to something. 5. particular, via fact any selection which may be expressed as a fraction is a rational selection. 6. No, via fact by ability of definition, an irrational selection is a non-repeating countless decimal. If it repeats, whether it repeats one hundred decimal places, that's expressed as a fraction. case in point, a million/7 is a repeating countless decimal, in spite of the undeniable fact that that's rational. pi is a non-repeating countless decimal, and so is irrational.

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.

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.
