Answer:

1. Óxidos são compostos binários formados pela reação do oxigênio com outros elementos.

2. Além disso, a tonificação também pode ficar feia e ocorrer em tons de preto e marrom. Nos casos mais graves, a tonalidade pode se transformar em corrosão e causar danos permanentes à superfície da moeda. Nos piores casos, a corrosão pode tornar a superfície da moeda porosa de tal forma que parece que foi tratada com jato de areia

3. (por exemplo, Li2O). Os óxidos são compostos binários de oxigênio com outro elemento, por exemplo, CO2, SO2, CaO, CO, ZnO, BaO2, H2O, etc. Estes são denominados como óxidos porque aqui, o oxigênio está em combinação com apenas um elemento.

Could you add coal and burn it completely without any pollution or waste?
algol [13]

Answer:

Explanation:

The waste coal industry argues that the best solution to waste coal piles is burning them, while other cleaner and safer alternatives exist. Rather than liberate the toxic contaminants by burning them, it is preferable to remediate the waste coal piles in a way that reduces the problems associated with the piles without creating new problems.

Every enzyme has a different what?
Montano1993 [528]

Answer:

Every enzyme has a different catalytic activity.

Explanation:

This means it can be used to do something that other enzymes can't, such as differentiating between sugars in order to change the sugar content of food.  

Another advantage? The wide range of uses for these enzymes when food preparation is approached creatively and with an open mind: With so many diverse tastes and textures to be found among edibles, an ample supply of suitable enzymes could enhance any dish!
