turns directly from its solid form (white crystalline powder) into a gas without passing through a liquid stage.Ībove the sublimation temperature of oxalic acid (314 degrees F) the remaining minor components of the material are only briefly in a vapor, before everything cools back down. The oxalic acid is heated until it sublimates, i.e. Swarm Queen is an epic strategy game in which you must battle for supremacy using your spawn of alien creatures. The swarm queen also has the Rapid Transfusion ability instead of Transfusion, which heals. They do not possess the Spawn Larvae ability. Dominate every alien queen in your way by spawning and controlling your minions to collect nectar and battle your way to victory. Compared to regular queens, they move more quickly when off the creep (although being on creep still gives them a movement advantage). Oxalic acid “vaporization” is somewhat of a misnomer, because the principal chemical change is actually sublimation, not vaporization. The swarm queen is a type of queen found in the StarCraft II: Heart of the Swarm single-player campaign and Co-op Missions. Unless you have, and are committed to always wearing, the required personal safety equipment, including a half-face respirator with acid gas cartridges, DO NOT ATTEMPT to use this method.
