Answer:
6. rust
7. oxygen
8. iron
9. extinguished
10. oxygen
Explanation:
Goodluck!!
Answer:
6.)materials made from iron when exposed to moisture may develop rusting.
7.) Aside from fuel or material ,oxygen or air and heat must be present for the combustion to occur
8.) Rusting occurs when iron, oxygen ,and water react with one another
9.) When oxygen supply is cut the flame will be extinguished.
10.) When overpopulation in an area occurs, a decrease or lack of oxygen for breathing may happen.
Explanation:
6.) When iron comes in contact with water or moisture in the air, water helps iron react with oxygen by breaking up the oxygen molecule. During the initial stages of rusting, iron loses electrons and oxygen gains electrons
7.) There must be fuel to burn down, there must be air to supply oxygen, and there must be heat to start and continue combustion process.
8.) Rusting is an oxidation reaction. The iron reacts with water and oxygen to form hydrated iron(III) oxide, which we see as rust. Iron and steel rust when they come into contact with water and oxygen – both are needed for rusting to occur.
9.) The main components of a flame are oxygen, fuel, and heat. Removing or lacking even one of the said ingredients will lead to the flame being extinguished.
10.) If the population grows, the oxygen supply will decrease since more individuals will use the majority of the land mass, which may result in tree cutting, and as we cut trees, we will lack oxygen support.
