why have hands? there are many reasons:
- pet the Shigaraki
- hold the Shigaraki
- cherish the Shigaraki
- forfeit all mortal posessions to Shigaraki
Glass reacts slowly with aqueous sodium hydroxide solutions at ambient temperatures to form soluble silicates. Because of this, glass joints and stopcocks exposed to sodium hydroxide have a tendency to "freeze". Flasks and glass-lined chemical reactors are damaged by long exposure to hot sodium hydroxide, which also frosts the glass. Sodium hydroxide does not attack iron at room temperature, since iron does not have amphoteric properties (i.e., it only dissolves in acid, not base). Nevertheless, at high temperatures (e.g. above 500 °C), iron can react endothermically with sodium hydroxide to form iron(III) oxide, sodium metal, and hydrogen gas.[22] This is due to the lower enthalpy of formation of iron oxide (−824.2 kJ/mol) compared to sodium hydroxide and positive entropy change of the reaction, which implies spontaneity at high temperatures and non-spontaneity at low temperatures . Consider the following reaction between molten sodium hydroxide and
