Answer:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
Explanation:
CH4(g) + 2O2(g) → CO2(g) + 2H2O(g)
Methane + oxygen → carbon dioxide + Water.
The balanced equation above shows the combustion of methane, CH4 in oxygen, O2 to yield carbon dioxide, CO2 and steam, H2O.
The mole ratio of combustion are as follows:
1 mole of CH4 burns in 2 moles of oxygen to produce 1 mole of CO2 and 2 moles of H2O and a lot of heat.
Answer:
simple machine
Explanation:
A seesaw is a simple machine, which just sways back and forth.
A complex machine is like a roller-coaster, or any other carnival game.
A mechanical machine has many screws, and is run by a human with a remote or something else.
The answer to the question has to be simple machine. Hope this helps!
I believe the answer is carbon dioxide. Because when carbon dioxide and water combine in the atmosphere it forms a very weak acid called carbonic acid, which falls to the Earth's surface as precipitation.
