Required Answer :-

Any reaction in which oxygen gas reacts with another substance is a combustion reaction

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

As We know that, combustion reaction is usually a reaction that produces fire. Combustion takes place at an elevated temperature. It is a heat releasing (exothermic), redox chemical reaction that usually occurs between a fuel and oxidizing agent (mostly oxygen of the atmosphere). The products released are often gaseous, and the resultant mixture is commonly called smoke. The products of combustion are called oxides.

Types of Combustion Reactions

1. Complete Combustion: Complete combustion takes place when a fuel burns completely to produce carbon dioxide and heat with a sufficient supply of oxygen. 2. Incomplete Combustion: In the case of a limited or partial supply of oxygen, the fuel burns incompletely, thereby producing carbon monoxide in place of carbon dioxide.

Some Examples of Combustion Reactions

Our vehicles such as cars, bikes, etc. run on fossil fuels. These fuels undergo a combustion reaction with oxygen to run the engine. Burning of wood or other solid fuels such as coal in winters: The carbon content present in wood or coal reacts with oxygen of the atmosphere to release heat and form other gaseous products.The liquefied petroleum gas is released from the cylinders through the holes in the burner. On complete combustion, it produces a clear blue flame. If the supply of oxygen is limited, the same flame turns yellowish and sooty.

As we already know, a combustion reaction cannot proceed in the absence of oxygen. For burning or combustion to take place, oxygen should be essentially present because it is the only gas that supports burning. A combustion reaction will always occur when a substance reacts with oxygen to release energy. For example, when methane burns in oxygen, it releases carbon dioxide and water. The formation of carbon dioxide shows the carbon present in the methane has undergone oxidation

The Methane is the major constituent of almost all hydrocarbons. Its combustion is represented by the following equation:

CH4 + 2O2 > CO2+ 2H2O+ energyEthane is a saturated hydrocarbon. When it reacts with oxygen, it produces water and carbon dioxide. 2C2H6 + 7O2 > 4CO2 + 6H2O + energy The food that we eat gets converted into glucose by the body. In the process of respiration, glucose is oxidized to produce carbon dioxide, water and energy. This energy is utilized for carrying out life processes. C6H12O6 + 6O2 > 6CO2+ 6H2O + energy

Answer from: Quest

answer: - 3.) the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

solution: - as per the rules, oxidation number of oxygen in its compounds is -2. the sum of oxidation numbers of all the elements of a molecule or compound is zero.

also, the oxidation number in elemental form is zero.

in no, the oxidation number of o is -2 so the oxidation number of n is +2 so that the sum is zero.

similarly, the oxidation number of c in co is +2 and o is -2.

on product side the oxidation number of n is 0 as it is in the elemental form( $n_2$ ) .

oxidation number of c in carbon dioxide is +4 as there are two oxygen in it and we know that each oxygen is -2.

so, oxidation number of n is changing from +2 to 0 and the oxidation number of c is changing from +2 to +4.

since nitrogen is reduced and hence no is acting as an oxidizing agent. carbon is oxidized and so co is acting as a reducing agent.

so, the right choice is number 3.)the oxidation state of nitrogen in no changes from +2 to 0, and the oxidation state of carbon in co changes from +2 to +4 as the reaction proceeds.

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, and calculate its density. here is a summary of the steps required: add water by clicking and holding prepare a known volume of water button. until the desired volume of water has been added. if more than the desired volume is added, click the reset button. button and redo the procedure. a single click will add about 21.0 ml of water. to set the mass, click and hold weigh out metal button. until the desired amount of metal is added to the weighing pan. once the desired mass of the metal is added, release the button. transfer the metal to water and then click on calculate density button. to see how the density is calculated using water displacement to measure the volume of the solid. to save time you can approximate the initial volume of water to â±1 ml and the initial mass of the solid to â±1 g. for example, if you are asked to add 23 ml of water, add between 22 ml and 24 ml. which metals in each of the following sets will have equal density? check all that apply.
