Hi there!
The oxygen we breathe is classified as Chalcogen and Nonmetal.
It is a gas.
And, the atomic weight is 15.9994
Hope this helps you!

One molecule of glucose has 6 carbon atoms. So if you have three molecules of glucose, simply multiply 3 by 6 carbon atoms. The correct answer is C. 18 Carbon atoms.
The correct answer for the second questions is C. Air. A homogenous mixture is a mixture in which its components are uniformly distributed throughout the mixture. It has a sigle phase.
Answer : Combustion reactions are those reactions which includes reacting with the oxygen along with the reactant.
Here, the reactant is cooking fat.
![C_{51}H_{88}O_{6} + 70 O_{2} ---> 51 CO_{2} + 44 H_{2}O](https://tex.z-dn.net/?f=C_%7B51%7DH_%7B88%7DO_%7B6%7D%20%2B%2070%20O_%7B2%7D%20---%3E%2051%20CO_%7B2%7D%20%2B%2044%20H_%7B2%7DO)
So when a long chain hydrocarbon which is cooking fat here reacts with oxygen the products obtained are carbon dioxide and water molecule.
One mole of fat reacts with 70 moles of oxygen and gives 51 moles of carbon dioxide and 44 moles of water molecule.
Answer and Explanation:
- Used as a construction frame material and for bending metal works because they are rigid and strong.
- Galvanising or coating the surface would prevent rusting.
N.B.: Mild steel is steel that has low carbon content, also called <em>carbon steel.</em>
