Question

Какая формула лавы?

Answer 1

Нет формулы
Лава - это расплав горных пород, преимущественно силикатного состава (SiO2) примерно от 40 до 95 %
Лава у разных вулканов различна. Она отличается по составу, примесям 
Карбонатная лава наполовину состоит из карбонатов натрия и калия.
Кремниевая содержит 53—62 % диоксида кремния
Базальтовая наполовину состоит из диоксида кремния, наполовину — из оксида алюминия, железа, магния и других металлов

Answer 2

Лава-расплав горных пород.
Формула лавы-SiO2

Answer 3

The Formula for Lava

Lava is a molten rock that flows from a volcano during an eruption. The formula for lava is based on the chemical composition of the molten rock. The most common type of lava is basaltic lava, which has the following chemical composition:

Chemical Composition of Basaltic Lava: - Basaltic lava is primarily composed of silica (SiO2), iron (Fe), magnesium (Mg), calcium (Ca), and aluminum (Al).

The specific formula for lava can vary depending on the exact composition of the molten rock, but the general chemical components mentioned above are characteristic of basaltic lava.

In summary, the formula for lava is not a single mathematical equation, but rather a representation of the chemical composition of the molten rock, with basaltic lava being the most common type.
