No. Metals do not contain carbon, so they cannot give off carbon dioxide.
Yes, in some conditions: magnesium, zirconium, uranium, etc.
yes
Can metal burned
Carbon form carbon dioxide by oxydation.
Green plants give out oxygen in the day time and take carbon dioxide and during the night the green plants give out carbon dioxide and take oxygen.
Plants get carbon dioxide from the air we exhale. We breath out carbon dioxide and plants give us oxygen. So when we breath oxygen the air that we exhale is carbon dioxide that goes to plants.
from atmosphere
Only if you are breathing.
All of them. At a high enough temperature, even diamond will burn, and produce (ridiculously expensive) carbon dioxide.
The equation is CS2 + 3 O2 -> CO2 + 2 SO2.
Air is mostly Nitrogen, but that is not the "burning" part; Oxygen is probably what you are looking for, as that is the part that helps the candle burn, without there would be no fire. Or maybe you are looking for Carbon dioxide, that is what burning candles (which are mostly carbon) produces. What gas causes a candle to burn? Oxygen. It is the oxygen in the atmosphere that chemically combines with the wax of the candle to give Carbon dioxide gas and water vapor. What does candle need from air to burn? A candle requires oxygen (O2) to continue its combustion reaction and produce CO2 and H2O.
To prepare and examine carbon dioxide:
Carbon dioxide! We give off carbon dioxide, plants give off oxygen. Its one carbon atom and two oxygen atoms.
Carbon dioxide, CO2
Carbon form carbon dioxide by oxydation.
Monkeys give off carbon dioxide when they exhale - the same as humans do!
Green plants give out oxygen in the day time and take carbon dioxide and during the night the green plants give out carbon dioxide and take oxygen.
Yes we do, we absorb the oxygen and give out carbon dioxide
plants release carbon dioxide and we give out oxygen .
It consumes carbon dioxide and lets off oxygen.
