How do you determine whether a gas given off during a chemical reaction is oxygen or hydrogen?

One way to determine whether a gas given off during a chemical reaction is oxygen or hydrogen is by performing a gas test. For example, the gas test for oxygen involves relighting a glowing splint when inserted into the gas. If the splint reignites, then the gas is oxygen. The gas test for hydrogen involves holding a lit match near the gas, and if a "pop" sound is heard, then the gas is hydrogen.


Is the gas necessary for combustion to take place carbon dioxide?

No, carbon dioxide is not necessary for combustion to take place. Combustion requires fuel, oxygen, and heat to occur. Carbon dioxide is one of the products of combustion when hydrocarbons are burned in the presence of oxygen.


When hydrogen gas and oxygen gas react as much oxygen gas than hydrogen gas is required?

The reaction between hydrogen gas and oxygen gas forms water, with 2 moles of hydrogen gas reacting with 1 mole of oxygen gas. This means that twice as much hydrogen gas is required compared to oxygen gas for the reaction to occur completely.


Why the three parts of this activity can be used to distinguish among oxygen hydrogen and carbon dioxide gas but not determine whether an unknown gas is one of these three?

What is a test to show that gas is oxygen?

One way to test for the presence of oxygen gas is to use a glowing splint test. If the gas is oxygen, the glowing splint will relight when introduced into the gas due to oxygen's ability to support combustion.


How could you show that a sample of a mystery gas was oxygen?

One way to determine that a sample of a mystery gas is oxygen is to perform a combustion test. If the gas supports combustion, creating a flame when exposed to a flame, it is likely oxygen. Additionally, using a chemical reaction with hydrogen peroxide and a catalyst to produce oxygen gas can also confirm the presence of oxygen in the sample. Finally, utilizing a gas sensor or gas chromatography to analyze the composition of the gas would further confirm if it contains oxygen.

How to test for oxygen?

One common way to test for the presence of oxygen is by using a glowing splint test. If you bring a glowing splint near a sample suspected to contain oxygen, it will ignite in the presence of oxygen. Another method is using a chemical like potassium permanganate, which will change color in the presence of oxygen.


What to use to make nitrogen oxide?

Nitric oxide (NO) can be made by reacting nitrogen gas (N2) with oxygen gas (O2) in the presence of a high temperature and pressure. Nitrogen dioxide (NO2) can be formed by the further oxidation of NO.


How many atoms are in oxygen gas?

Oxygen gas (O2) is diatomic, meaning it consists of two oxygen atoms chemically bonded together. Therefore, to determine the number of atoms in oxygen gas, we consider the molecular formula. In one molecule of oxygen gas (O2), there are two oxygen atoms. Avogadro's number (6.022 x 10^23) represents the number of entities (atoms, molecules, etc.) in one mole of a substance. Therefore, in one mole of oxygen gas, there are 2 moles of oxygen atoms, equivalent to approximately 1.204 x 10^24 oxygen atoms.


How would you test a gas to prove it was oxygen?

One way to test if a gas is oxygen is by using a glowing splint test. A glowing splint placed in a test tube of the gas will reignite if the gas is oxygen. Another method is to use a colorimetric test strip specifically designed to detect oxygen, which will change color in the presence of oxygen gas.


How do you know that the gas liberated is oxygen?

One way to confirm that the gas liberated is oxygen is by performing the gas test. Place a glowing splint into the gas sample - if the splint re-ignites, it indicates the presence of oxygen due to its ability to support combustion. Additionally, oxygen can also be identified by its colorless and odorless characteristics.


How will you prove the presence of diffused air in water?

One way to prove the presence of diffused air in water is by observing the formation of bubbles when the water is agitated or heated. Another method is to measure the dissolved oxygen levels in the water using a dissolved oxygen meter, as air typically contains oxygen gas.


What do you conclude about one of the properties of the gas in the beaker based on the behavior of the burning splint?

If the burning splint is extinguished upon entry into the beaker, one could conclude that the gas in the beaker is likely non-flammable or oxygen-depleted. If the splint continues burning, this suggests the presence of oxygen in the beaker.


Is H2O what you get if you mix hydrogen and oxygen?

No. Simply mixing hydrogen and oxygen will not get you water. You must burn the mixture.


Is the gas necessary for combustion to take place carbon dioxide?

No, carbon dioxide is not necessary for combustion to take place. Combustion requires fuel, oxygen, and heat to occur. Carbon dioxide is one of the products of combustion when hydrocarbons are burned in the presence of oxygen.
