It is a <u><em>chemical compound</em></u> formed with a metal (mainly positive cations) with oxygen.
It is formed through the air as they react in the air together.
They are also BASES - ALKALINE (so neutralise acids)
Answer:
V=12.6148888506L
Explanation:
using charles law Volume1/Temperature1 = Volume2/Temperature2
13.4L/(17C+273.15C)=V/273.15K
remember gas equations require kelvin not celcius so converting celcius to kelvin is Celcius + 273.15 which is standard temperature conditions
They have to be closed up in a bag
The answer would be a. C2H4(ethylene)
1C2H4+3O2~>2CO2+2H2O
