Summary
[edit]DescriptionPure chemical energy.jpg |
English: The combustion of magnesium in air is highly energetic. Released bright light is so intense that can dazzle. But when the reaction is controlled, the effect looks like getting pure chemical energy.
Polski: Spalanie magnezu w powietrzu jest reakcją wysoce energetyczną. Powstałe w jej wyniku jasne światło jest w stanie oślepić. Kontrolowane spalanie daje efekt otrzymywania czystej energii chemicznej.
Русский: Сгорание магния в воздухе - очень энергичная реакция. Oбразовавшийся яркий свет может ослепить. Контролируемое сгорание даёт эффект получения чистой химической энергии. English: The reaction of combusting magnesium metal in air, initiated by heating this element in melting-pot using flame of a gas burner. After long heating magnesium reacts violently with oxygen in air and as a result magnesium oxide is formed. |
