Oxygen + Glucose > Water + Carbon Dioxide
or
iron + oxygen ---> Ironoxide
colour change fizzing new substance produced
H2o
This is a physical change, not a chemical one, but you can write an equation. CO2(g) --> CO2(l) However, make sure you write the 2's as subscripts.
write chemical equation for the reaction between viscose solution and sulphuric acid
Evaporation is not a chemical reaction.
colour change fizzing new substance produced
They write a chemical equation.
Writing out a chemical equation for a specific chemical reaction.
H2o
We see the chemical reaction but we write the chemical equation.
MgCO3 --(heat)--->MgO+CO2
This is a physical change, not a chemical one, but you can write an equation. CO2(g) --> CO2(l) However, make sure you write the 2's as subscripts.
This is not an equation but the chemical symbol of the cation: Ba2+.
This chemical equation is:2 H2 + O2 = 2 H2O
The chemical formula (not equation) of sodium hydrogen sulfite is NaHSO3.
2Na(s) + 2H2O ===> 2NaOH + H2(g). What happens is a vigorous reaction, so stand back.
Sorry i forget
