I need help completing and balancing equations

﻿﻿Mg+O2 -->

KOH + NHO3 -->

Febr3 + KOH-->

CuSO4 + Na-->

C6H14+O2 -->

﻿﻿

smallest set of whole number coefficients and classify as a single replacement, etc

First reaction is synthesis:

2Mg + O2 --> 2MgO

Second reaction is double replacement or neutralization

KOH + HNO3 -->  KNO3  + HOH

Third reaction would also be double replacement

FeBr3 + 3 KOH --> Fe(OH)3  + 3 KBr

Fourth reaction is single replacement:

CuSO4 + 2 Na  -->  Na2SO4  + Cu

Last reaction is combustion:

2 C6H14  +   19 O2  -->  12 CO2  + 14 HOH

2Mg + O2 => 2MgO

KOH + HNO3 =>  KNO3  + HOH

FeBr3 + 3KOH => Fe(OH)3  + 3KBr

CuSO4 + 2 Na  =>  Na2SO4  + Cu

2C6H14  +   19O2  =>  12CO2  + 14HOH
