Answer:
1. CH4COOH + NaHCO3 → NaC2H3O2 + H2O + CO2
2. Ca(OH)2+ CO2→ CaCO3 + H2O.
3.4Fe + 3O2 + 6H2O → 4Fe(OH)3
1.
When the substances are mixed together, hydrogen ions in the vinegar react with the bicarbonate ions in the baking soda. This reaction results in two new chemicals:
1) carbonic acid
2) sodium acetate.
2.
On reaction of lime water with carbon dioxide, it forms calcium carbonate which is insoluble salt and water.
3.
On reaction with oxygen and water iron forms rust(iron oxide)
Which is a natural process that causes the lower layers to be protected against the exposure to moisture or air.
i think something is missing in part 4 ,magnesium needs something to react
