The above chemical equation took me quite a while to balance. 🙂
Balancing of equations is crucial because it will affect the calculations of mole, mass of reactants and volume of gas which is another chapter altogether.
Attention all hannahtuition Science students, please balance the following chemical equations after receiving my mobile msg. You may either write on piece of paper OR copy and paste these equations with your answers on the comment below.
Have Fun! 🙂
1) __SeCl6 + __O2 —-> ___SeO2 + __Cl2
2) __(NH4)3PO4 + __Pb(NO3)4 —> __Pb3(PO4)4 + __NH4NO3
3) __KOH + __H3PO4 —> __K3PO4 + __H2O
4) __H3PO4 + ___HCl —> __PCl5 + __H2O
5) __Ca3(PO4)2 + ___H2SO4 —> __CaSO4 + __Ca(H2PO4)2
6) ___H2SO4 + __MgCO3 —> __MgSO4 + __CO2 + __H2O
7) __NH4NO3 —> __N2 + __O2 + __H2O
8) __ V2O5 + ___HCl —> __VOCl3 + __H2O
9) __As + ___NaOH —> __Na3AsO3 + __H2
10) __(NH4)2CO3 —> __NH3 + __CO2 + __H2O
Proved to be a challenge 🙂
These are just warm-up.
I got even more challenging ones!! hehe.
Reblogged this on jamesharl – study and write and commented:
I think this helps in understanding equations. This reminds me of my life as a student…
Hi Jamharl, do let me know if you wants the answers for these questions. 😉
