Acetylene gas C2H2 reacts with oxygen If 2 moles of acetylene react completely with oxygen how many grams of carbon dioxide are produced?
First you need to work out the balanced equation. 2C2H2 + 5O2 -----> 4CO2 + 2H2O From this we see that 2 moles of acetylene produces 4 moles of carbon dioxide. 1 mole of carbon dioxide is 12 + 16 + 16 = 44g (adding the mass numbers of the component elements). If 1 mole = 44g then 4 mole = 176g
How does the entropy change in the reaction 2C2H2(g) plus 5O2(g) 4CO2(g) plus 2H2O(l)?
In the reaction 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l), the entropy decreases. This is because the reactants consist of gaseous molecules, which have higher entropy due to their greater freedom of movement, while the products include liquid water, which has lower entropy. Additionally, there is a reduction in the number of gas molecules from 7 (2 C2H2 + 5 O2) to 4 (4 CO2), further contributing to the decrease in disorder. Overall, the transition from gas to liquid and the reduction in the number of gas molecules results in a net decrease in entropy.
When a hydrocarbon undergoes combustion it reacts with and produces?
FeedbackThe correct answer is: 2C2H2 + 5O2 4CO2 + 2H2O.
What reaction takes place during oxyacetylene gas welding?
During oxyacetylene gas welding, acetylene gas and oxygen are mixed in a torch and ignited to produce a high-temperature flame. The heat from this flame melts the metal being welded, while the oxygen assists in the combustion process by providing additional heat and reacting with the metal to form an oxide layer that is then removed as slag.
How many grams of water are formed when 5.00g of butanol combust with excess oxygen?
To determine the number of grams of water formed, we need to calculate the moles of butanol (C4H9OH) and then use the balanced chemical equation to find the moles of water produced in the combustion reaction. From there, we convert moles of water to grams. The balanced equation for the combustion of butanol is C4H9OH + 6O2 → 4CO2 + 5H2O.
What is the balanced equation for the complete combustion of Ethyne?

What type of Balanced equation for the complete oxidation reaction that occurs when acetylene C2H2 burns in air?
The balanced equation for the complete oxidation of acetylene (C2H2) burning in air is: 2C2H2 + 5O2 -> 4CO2 + 2H2O. This equation shows that two molecules of acetylene react with five molecules of oxygen to produce four molecules of carbon dioxide and two molecules of water.
How many grams of carbon dioxide are produced from the combustion of 1.3 moles of acetylene C2H2?
The balanced chemical equation for the combustion of acetylene is: 2C2H2 + 5O2 → 4CO2 + 2H2O. This means 2 moles of C2H2 produce 4 moles of CO2. Therefore, 1.3 moles of C2H2 will produce 2.6 moles of CO2, which is equivalent to approximately 84.8 grams of CO2.

How do you write the formula when acetylene burns in air to form carbon dioxide and water?
The balanced equation for the combustion of acetylene (C2H2) in air to form carbon dioxide (CO2) and water (H2O) is: 2C2H2 + 5O2 -> 4CO2 + 2H2O
10 grams of C2H2 and 10 grams of O2 is ignited the resultant combustion reaction produces CO2 and H20 Write the balanced formula?
The reaction is: 2 C2H2 + 5 O2 -------------- 4 CO2 + 2 H2O.
What is the oxidation and reduction in 2C2H2 plus 5O2 equals 4CO2 plus 2H2O?
The C2H2 us being oxidized, electrons stripped away, and the oxygen is being reduced, accepting electrons and in this case, carbon and hydrofen are coming along for the ride.
What is the chemical Equation for incomplete combustion of ethene?
there are many possible combinations, as incomplete combustion refers only to the combustion of a fuel whereby not all of a fuel's carbon and hydrogen is converted to carbon dioxide and water, usually other products involve carbon particulates (C) or carbon monoxide (CO) as such two possible equations are:C2H4 + O2 => C2 + 2H20C2H4 + 2O2 => 2CO + 2H2O
How does the entropy change in the reaction 2C2H2(g) plus 5O2(g) 4CO2(g) plus 2H2O(l)?
In the reaction 2C2H2(g) + 5O2(g) → 4CO2(g) + 2H2O(l), the entropy decreases. This is because the reactants consist of gaseous molecules, which have higher entropy due to their greater freedom of movement, while the products include liquid water, which has lower entropy. Additionally, there is a reduction in the number of gas molecules from 7 (2 C2H2 + 5 O2) to 4 (4 CO2), further contributing to the decrease in disorder. Overall, the transition from gas to liquid and the reduction in the number of gas molecules results in a net decrease in entropy.
What is the chemical equation for acetylene gas C2H2 burns in a welding torch with oxygen to form carbon dioxide gas and water vapor?
2C2H2(g) + 5O2(g) = 2H2O(g) + 4CO2(g) or, 2 Acetylene molecules + 5 Oxygen molecules = 2 water molecules + 4 Carbon dioxide molecules (+ energy)
