Times it bye for then ur answer will be 80
The answer is most likely nonmetals. :)
Hi there!
One of the main causes of air pollution is smoking.
Smoking affects not only humans, but pets and animals as well. Animals can get cancer too!
Another big cause of pollution is cars. Gasoline of course comes out into the air after it is used. It also affects animals.
A lot of people know that we should change this, but hardly anyone is really doing anything to try and stop it.
I know this is a short answer, but I hope it helps!
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
