Yes water is produced. Oxygen accepts protons to produce water
there are 8 electrons in an oxygen atom, equal to the number of protons. there are 6 valence electrons though, give or take because they constantly switch
To find the number of protons, you use the atomic number. The atomic number is always the same number of protons. To find the average number of neutrons, you use the atomic mass and take away the number of protons. For example Oxygen has an atomic number of 8 and an atomic mass of 16.01, so since it has an atomic number of 8, it always has 8 protons, and since oxygen has a mass of 16.01, it has an average of 8.01 neutrons (the math: 16.01 mass-8 protons=8.01 neutrons). If your dealing with isotopes, you round the mass number. The mainest isotope is 8 neutrons in oxygen, but there is a few oxygen atoms that have 9 neutrons which is why the average mass is little higher than 16.

No, your lungs can take in only as much as their capacity, no more.
If you had looked in the periodic table, you would have seen that the element Oxygen has an atomic mass of 16 (or more precisely 15.9994) and if you were to take that atomic mass and subtract the atomic number from it (i.e. 8) you would get a difference of 8 which is the number of neutrons it contains. In short, oxygen is that element.
The percentage of oxygen in water, vapors or ice is the same.
it iz not take much i quess
how is the symbol for copper different from that of oxygen? explain why
Yes organisms take oxygen from the air and aquatic organisms take oxygen from the water using their gills. Some do. Most only from one or the other. For example a tuna fish gets pretty much all its oxygen from oxygen dissolved in water. Humans get all our oxygen from the air. Mudskippers get oxygen from both. Yes. Land animals take in oxygen that plants release using their noses. On the other hand, aquatic or marine animals take in oxygen using their gills.
We know that sodium is atomic number 11, and it has 11 protons, 11 electrons (in a neutral atom), and will have 12 neutrons in its sodium-23 isotope. Sulfur is atomic number 16, and will have 16 protons, 16 electrons (in a neutral atom), and will have 16 neutrons in it sulfur-32 isotope. Oxygen has atomic number 8, and has 8 protons, 8 electrons (in a neutral atom) and will have 8 neutrons in its oxygen 16 isotope. If we take 2 sodium atoms, a sulfur atom and 4 oxygen atoms, we'll have a total of 70 protons, 72 neutrons and 70 electrons in sum.
I think when they receive carbon dioxide
