I need help with chemistry

Question

I need help with knowing what is the product of baking soda and vinegar. What products can possibly form when methane gas reacts with oxygen gas from the air. Is methane gas and oxygen gas a possible ending substance or not.

Answer 1

No! Methane gas (CH₄) and any hydrocarbon can react with oxygen to form CO₂ and H₂O. The reaction is called combustion and it would be written as CH₄ + O₂ ---> CO₂ + H₂O. We would put a "2" in front of the water and a "2" in front of the O₂ to balance the equation, so CH₄+ 2O₂---> CO₂ + 2H₂O, For the baking soda/acetic acid reaction, the equation is Na₂CO₃ + CH₃CO₂H----->NaCH₃CO₂ +H₂O + CO_2. Put a "2" in front of the CH₃CO₂H and the equation will be balanced, Na₂CO₃ + 2CH₃CO₂H--->2NaCH₃CO₂ + CO₂ +H₂O.

Answer 2

Baking soda is also called sodium bicarbonate and has the formula NaHCO₃

Vinegar is a dilute solution of acetic acid and has the formula CH3COOH

NaHCO₃ + CH₃COOH ==> CH₃COO^-Na⁺ + H₂CO₃ --> H₂O + CO₂ + Na⁺ + CH₃COO^-

Methane is CH4 and oxygen is O2

CH₄ + 2O₂ ==> CO₂ + 2H₂O ... balanced reaction

The products from complete combustion of methane with oxygen are CO2 and H2O

Other possible product from incomplete combustion of methane are CO (carbon monoxide) and methane (not really a product, but left over as an "ending substance" if not all is consumed)

Oxygen is not a product but may be present as an "ending substance".
