Explanation:
Across the world, amphibians have been disappearing at an unprecedented rate — faster than any other group of animals. Frogs, toads, and salamanders are extremely sensitive to environmental changes caused by habitat destruction, climate change, pollution, and invasive species.
Answer:
- Oxido de magnesio
Explanation:
Mg → magnesio
O → oxígeno
La unión del oxígeno (no metal) con un metal, forma el determinado óxido que se nombra como óxido de .... y el no metal.
En este caso, podemos deducir que el contenido del frasco es de óxido de magnesio, aunque viendo que hay un sólo átomo de oxígeno podemos llamarlo como monóxido de magnesio, similar al CO (monóxido de carbono).
A partir de que el magnesio sólido entre en contacto con el aire, se produce MgO de acuerdo a la siguiente reacción:
2Mg + O₂ → 2MgO
<span>Melting point. The alkali metals have low melting and boiling points compared to most other metals. Apart from the other alkali metals, only three metals (indium, gallium and mercury) have lower melting points than lithium. ... The melting points then decrease as you go down the group.
