What does oxygen make. In this process the plants combine solar energy with carbon dioxide and water to produce sugars and oxygen. An oxygen concentrator is a device that concentrates the oxygen from a gas supply typically ambient air by selectively removing nitrogen to supply an oxygen enriched product gas stream. Overall it s the most abundant element on the earth s surface and the third most abundant in the universe after hydrogen and helium.
At standard temperature and pressure two. Oxygen could cause the flame of a lighter to flare or a lit match to burst into an unexpectedly large flame leading to a burn on the person. It can be produced by machines oxygen diffuser electrolyzer rust deoxidizer filtered from polluted oxygen by deodorizers or cooling to liquid form or a small amount created by the algae terrarium.
The first answer is c condensation is a physical process and the others are chemical. Two thirds of the human body is composed of oxygen. In the cells oxygen combines with other chemicals making them oxidized.
Plants produce oxygen through the process of photosynthesis. It is a member of the chalcogen group in the periodic table a highly reactive nonmetal and an oxidizing agent that readily forms oxides with most elements as well as with other compounds after hydrogen and helium oxygen is the third most abundant element in the universe by mass. It is a breathable gas and required by duplicants to survive.
Oxygen can also be produced as the result of a chemical reaction in which oxygen is freed from a chemical compound and becomes a gas. Oxygen is not usually stable in an atmosphere and without a constant source to replace that which bonds with other materials the atmosphere eventually becomes oxygen depleted. Chemistry 27 01 2021 23 50 princess6039 what does oxygen and sulfur make.
In humans oxygen is taken in through the lungs and distributed via the blood stream to cells. The second answer is b it doesn t change depending on location the answer you chose the third answer is a. This method is used to generate limited quantities of oxygen for life support on submarines aircraft and spacecraft.
What does oxygen and sulfur make. Two methods in common use are pressure swing adsorption and membrane gas separation. Oxygen accounts for about 23 of the atmosphere s mass with pairs of oxygen atoms stuck together to make dioxygen molecules but it s not just in the air we breathe.
Oxygen is one of the resources in the game oxygen not included. The oxygen would make the situation that much worse. Oxygen is the chemical element with the symbol o and atomic number 8.

A combustion reaction occurs when a compound merges with oxygen to release heat in an exothermic reaction.
Acetylene and oxygen reaction. The balanced equation for the reaction of acetylene c2h2 and oxygen in an acetylene torch is 2 c2h2 5 o2 4 co2 2 h2o. You have 10 g of c2h2 and 10 g of o2. The products of the complete combustion of acetylene gas in an atmosphere of oxygen are water or water vapour and carbon dioxide.
When a mixture of 10 g of acetylene and 10 g of oxygen is ignited the result is combustion. In the presence of a flame acetylene reacts with oxygen to form carbon dioxide and water. The room temperature reaction of acetylene with atomic oxygen was studied in a moderately fast flow system.
2 h 2 c 2 g 5 o 2 g 4 co 2 g 2 h 2 o g because of the visual display this demonstration is sometimes referred to as fire rocks see demonstration 5 20k. The balanced equation for the combustion of acetylene is 2 h2c2 5 o2. In this reaction the number of grams of oxygen required to react wit.
This is a type of reaction wherein a large amount of heat is given up. 4 co2 2 h2o. Mechanism of co fourth positive v u v chemiluminescence in the atomic oxygen reaction with acetylene.
In the reaction 2 h2c2 5 o2. The oxidation of acetylene was studied using sufficiently high gas densities and concentrations of inert gas to keep the reaction isothermal and reduce boundary layer effects. The reaction does not go to completion in direct manner as indicated but occurs in two stages primary and secondary combustion.
The course of the reaction was followed using both a mass spectrometer and a photometric. 4 co2 2 h2o two molecules of acetylene combine with five compounds of two bonded oxygen atoms to form four molecules of carbon dioxide and two molecules of water.
