Answer 1

Answer:

see below *Just a tip, be VERY careful when you are typing your equations.

Explanation:

1 H2 + O2 → H20 = 2H2 + O2 → 2H20

Na + Cl2 → NaCl = 2Na + Cl2 → 2NaCl

N204  → NO2 = N204 → 2NO2

Mg +02 → MgO = 2Mg +02 → 2MgO

H202 → H2O + O2 = 2H202 → 2H2O + O2

Ca + N2 → Ca3N2 = 3Ca + N2 → Ca3N2

Li + F2 →  LiF = 2Li + F2 →  2LiF

Mg + N2 → Mg3N2 = 3Mg + N2 → Mg3N2

NH3 → N2 + H2 = 2NH3 → N2 + 3H2

HCl → H2 + Cl2 = 2HCl → H2 + Cl2

NI3 → N2 + 12 = 2NI3 → N2 + 3I2

HI  → H2 + 12 = 2HI  → H2 + I2

AI + 02 → A1203  = I believe this question got typed in incorrectly (It could be Al + O2 → Al2O3 = 4Al + 3O2 → 2Al2O3)

K+S → K2S = 2K + S → K2S

Li + Cl2 → LICI = 2Li + Cl2 → 2LiCI

Na + H2O →  NaOH + H2 = 2Na + 2H2O →  2NaOH + H2

CH4 + 02 → CO2 + H20 = CH4 + 202 → CO2 + 2H20

PbO + C → Pb + CO2 = 2PbO + C → 2Pb + CO2

CO + 02 → CO2 = 2CO + 02 → 2CO2

Al+S → A1253 = I believe this question got typed in incorrectly (It could be Al + S → Al2S3 = 2Al + 3S → Al2S3)

Answer 2

Answer:

read the book read the book and get the answer for your question on your standard read the roli when mum was teaching and see and read questions the rule ok bye that's all NH2 plus O2 who is equal to H2 you can know the answer now n a o h + H2 you come H2 ch4 plus 022
