BALANCING EQUATIONS

Question 1

SOLID SOSIUM + liquid h2o make Hydrogen gas and aqueous sodium hydroxide

Answer 1

2Na(s) + 2H2O (l) > H2 (g) + 2NaOH (aq)

Question 2

Gas Evolution Reaction with METAL+ACID = ?GAS?

Answer 2

H2 ALWAYS

Question 3

Gas evolving reaction
Carbonate + ACID = ??
CO3 2- + HCl = ??

Answer 3

CO2 gas (+ H2O + Salt)

*The acid donates a proton H which strips an O from Carbonate (aq) because CO3 is unstable with 2 extra electrons, CO2 is now a stable compound as a product )
This results in the formation of stable CO2 gas

Question 4

Gas evolution reaction
SulfITE + ACID = ??
SO3 2- + HCl = ??

Answer 4

SO2 gas

Question 5

NH4 + STRONG BASE

Answer 5

NH3 (g)
