acids wont change their color in methyl orange. bases changes the color when they are present in methyl orange.
HCl is white or no color in methyl orange.

Product depends on reaction conditions and quantity of sodium hydroxide used in the reaction. Initially sticky product [sodium salt of methyl salicylate] will form that on heating will effect saponification [hydrolysis of ester] resulting in sodium salicyale.

Methyl orange acts as a pH indicator in the process of sodium carbonate and hydrogen chloride titration. The addition of methyl orange will indicate the ratio of sodium carbonate to hydrogen chloride by the colour which develops.
dark green (but orange - brown if left standing)
Sodium hydroxide is a colourless liquid, and it is also called as caustic soda.
Methyl orange changes color from red to yellow at a pH of around 4.4 to 3.1. In the titration process, the color change indicates the endpoint of the reaction between the sodium carbonate and the acid being used. This allows for precise determination of the amount of sodium carbonate present in the solution.

No, none of the mentioned chemicals (methyl orange, copper sulfate, sodium hydroxide, calcium carbonate, sodium carbonate) are explosive or typically used in smoke bombs. However, copper sulfate can be flammable if exposed to high temperatures or flames. It's important to handle these chemicals with care and follow safety guidelines when using them.
