my best guess is tht u posted this question then answered it w/ non-answer
When steam is passed over iron it creates a magnetic oxide of iron called triiron tetroxide, Fe3O4.
Na2O + CO2 -> Na2CO3 Balanced as is and I would call this a synthesis reaction.
Cl2(g)+F2(g) --> 2ClF(g)
We see the chemical reaction but we write the chemical equation.
Na2O + CO2 >> Na2CO3Balanced. Single displacement, I think. SYNTHESIS
2KBr + 2H2O----->2KOH + Br2 + H2(g) this is the reaction in electrolysis of KBr in aqueous solution
Phosphine is not very soluble in water compared to nonpolar substances. If you were to write a balanced equation for the reaction of PH3 with water, it would be an equilibrium reaction.
Symbol equations for reactions are written using chemical formulae.
I'm not entirely sure but an unbalanced equation is: Mg + O2 -----> MgO
It is: C2H5OH+3O2 ----> 2CO2+3H2O
The actual formula is KClO3 (with a lowercase L) Balanced equation: 2KClO3 --> 2KCl + 3O2
2h2 + o2 2h2o
2 H2 + O2 = 2 H2O
Na2O + CO2 -> Na2CO3 Balanced as is and I would call this a synthesis reaction.
To determine the stoichiometry of a reaction, you must first write out a balanced equation describing the reaction and then use the coefficients of this statement to represent molar ratios.
Cl2(g)+F2(g) --> 2ClF(g)
2Al + 3CuCl2 --> 3Cu + 2AlCl3
Sulfuric acid can be mixed with water but doesn't react.
