Answer:
The correct formula for tetraphosphorous octaoxide is P₂O₅
The reactivity of a metal is determined by these things.
Firstly, the number of electrons in the outer shell; the fewer the number of electrons in the outer shell, the more reactive the metal.
The number of electron shells also affects reactivity, the more electron shells there are, the more reactive the metal.
A study of structure, behavior, physical, and natural world through observation and experiment. Science can help you understand the real world, also it can be really fun if you give it a try :)
Answer:
reason is Heat is involved, the reaction is exothermic and therefore heat is lost to the surrounding
I think c? Hydroelectric power reduces pollution, and A, B are irrelevant.
