_NaHCO(s) --> _CO2+_NaCO(s)+_H2O<br><br>balance the equation

elena55 [62]

The balanced equation :

2NaHCO₃⇒CO₂ + Na₂CO₃+H₂O

<h3>Further explanation</h3>

Given

Reaction

NaHCO(s) --> _CO2+_NaCO(s)+_H2O

Required

The balanced equation

Solution

Maybe the equation should be like this :

NaHCO₃⇒CO₂ + Na₂CO₃+H₂O

Give a coefficient

NaHCO₃⇒aCO₂ + bNa₂CO₃+cH₂O

Make an equation

Na, left=1, right=2b⇒2b=1⇒b=1/2

H, left=1, right=2c⇒2c=1⇒c=1/2

C, left=1, right=a+b⇒a+b=1⇒a+1/2=1⇒a=1/2

The equation becomes :

NaHCO₃⇒1/2CO₂ +1/2Na₂CO₃+1/2H₂O x2

2NaHCO₃⇒CO₂ + Na₂CO₃+H₂O

Describe how oxidation and reduction involve electrons, change oxidation numbers, and combine in oxidation reduction reactions

borishaifa [10]

Answer: Oxidation is defined as the reaction in which there is loss of electrons. It is accompanied by increase in oxidation number.

$Zn\rightarrow Zn^{2+}+2e^{-}$

Zinc in solid state has oxidation number of zero and on losing electrons changes to $Zn^{2+}$ with oxidation number of +2.

Reduction is defined as the reaction in which there is gain of electrons. It is accompanied by decrease in oxidation number.

$2H^++e^{-}\rightarrow H_2$

Hydrogen ions with +1 oxidation state gains electrons and converts to molecular hydrogen with oxidation state of zero.

In the given redox reaction, both oxidation and reduction takes place. They go hand in hand.

$Zn+H_2SO_4\rightarrow ZnSO_4 +H_2$

Zinc converts to $Zn^{2+}$ and gets oxidized. $H^+$ gains electron and convert to $H_2$ .
