Answer: False
Explanation: The chemical hazard label indicates the class of harzard of chemical products. It appears on their Safety Data Sheet (SDS), which contains a lot of informations about these substances.
The chemical hazard label is divided into four colors and which one has a meaning (categorie) connected with a number, like:
Blue: Health hazard - If the chemical is deadly (4), extreme danger (3), hazardous (2), slightly hazardous (1) or a normal material (0).
Red: Fire hazard (flammability) - If the chemical has flash point bellow 73ºF (4), bellow 100ºF (3), above 100ºF not exceeding 200ºF (2), above 200ºF (1) or will not burn (0).
Yellow: Reactivity (it can be related to instability) - If the chemical may detonate (4), shock and heat may detonete it (3), if it can suffer a violent chemical change (2) or unstable if heated (1) or if it is stable (0).
White: Specific hazard - If the chemical is acid (ACID) or alkali (ALK), for example.
Answer: NaNO3 (Sodium Trioxonitrate (V) )
Explanation:
The equation of the reaction is; HNO3 + NaOH -----> H2O + NaNO3
When acids react with water, H ions are released which then combine with water molecules to form H₃O⁺
