The evaluation model of educational applications is composed of categories that have technical and pedagogical dimensions, aiming to evaluate the applications based on the balance between them.
Same fact, two readings: In aqueous media, the transition from CO2 to H2CO3 involves the formation of the bicarbonate ion. Alternatively, the protonation of bicarbonate is regulated by both kinetic and thermodynamic factors.
Theia's remains were deposited over the proto-Earth when the Moon was formed by the collision of these proto-planets. As consequence, significant amounts of heavier essential elements became available and allowed the evolution of live in the Earth.
