in the reaction c o2 → co2, 18 g of carbon react with oxygen to produce 72 g of carbon dioxide. what mass of oxygen would be nee
Strike441 [17]
From the given balanced chemical reaction,
                                   C + O2 -> CO2
the mass ratio of the carbon and oxygen that is needed for the reaction is 12:32. Simplifying the ratio gives 3 unit mass C is to 8 unit mass O2. Given 18 g of carbon,
           18 g x (32 g oxygen / 12 g carbon) = 48 grams. 
For the given product, the ratio of oxygen to carbon dioxide is 32: 44.
                      72 g CO2 x (32 g O2 / 44 g CO2) = 52.36 grams

What happens to the effenciency of the exchange of oxygen in the human body at a high altitude​
Daniel [21]

Answer:

The effiency decreases at higher altitudes

Explanation:

The higher up a person is on a mountain, the thinner the air is due to the lack of plants that can grow. An example of this is Mount Everest. At a certian point on the mountain, called the "Death Zone", the air is too thin to supply enough oxygen to the human body to survive. That's why they bring oxygen tanks with them on their adventures.

(ANSWER IF U CAN PLEASE) Atoms, Elements, Compounds, and Chemical Bonds
Brut [27]

Answer:

Atomic Models Of Elements: Atoms consist of three basic particles: protons, electrons, and neutrons. The nucleus (center) of the atom contains the protons (positively charged) and the neutrons (no charge). ... Atoms are made up of protons and neutrons located within the nucleus, with electrons in orbitals surrounding the nucleus.

Lithium:Lithium is a chemical element with the symbol Li and atomic number 3. It is a soft, silvery-white alkali metal. Under standard conditions, it is the lightest metal and the lightest solid element. because it is present in trace amounts in virtually all rocks.

Florine:Fluorine is a chemical element with the symbol F and atomic number 9. It is the lightest halogen and exists at standard conditions as a highly toxic, pale yellow diatomic gas. As the most electronegative element, it is extremely reactive, as it reacts with all other elements, except for argon, neon, and helium.

Electron:Electron is a free and open-source software framework developed and maintained by GitHub. It allows for the development of desktop GUI applications using web technologies: it combines the Chromium rendering engine and the Node.js runtime.

Neutron:The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton. Protons and neutrons constitute the nuclei of atoms.

Proton:A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron. Protons and neutrons, each with masses of approximately one atomic mass unit, are jointly referred to as "nucleons".
