How many molecules are present in 3 moles of methanal?
The reaction is :- 2C2H6 + 7O2 ----------> 4CO2 + 6H2O When one mole ethane is combusted 7/2 moles of oxygen are used. When 3 moles of ethane are combusted 3 x 7/2 moles of oxygen used. No. of oxygen molecules consumed =6.022 x 1023 x7/2= 21.077 x 1023=2.107 x 1024 molecules.
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 reaction when C2H6 gas is combusted?
The chemical reaction when C2H6 gas (ethane) is combusted is: 2C2H6 + 7O2 -> 4CO2 + 6H2O. Ethane reacts with oxygen to produce carbon dioxide and water.
How many molecules of o2 would react with 56 c2h6 molecules according to the following balanced equation 2c2h6 plus 7o2 4co2 plus 6h2o?
According to the balanced equation (2 \text{C}_2\text{H}_6 + 7 \text{O}_2 \rightarrow 4 \text{CO}_2 + 6 \text{H}_2\text{O}), 2 molecules of (\text{C}_2\text{H}_6) react with 7 molecules of (\text{O}_2). Therefore, 56 molecules of (\text{C}_2\text{H}_6) would react with ( \frac{7}{2} \times 56 = 196 ) molecules of (\text{O}_2).
How many oxygen atoms are in 4co2?
There are 8 oxygen atoms in 4CO2 molecules. Each carbon dioxide molecule has 2 oxygen atoms, so 4 CO2 molecules would have a total of 8 oxygen atoms.
How many atoms are found in 4co2?
There are 3 atoms in one CO2. So there will be 12 atoms in 4CO2.
What molecules are produced in the Krebs cycle?

What is the stoichiometry answer to 2c2h6 7o2 4co2 6h2o?
The balanced equation for this combustion reaction is 2C2H6 + 7O2 -> 4CO2 + 6H2O. This means that for every 2 molecules of C2H6, we need 7 molecules of O2 to produce 4 molecules of CO2 and 6 molecules of H2O.
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.
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)

how many elements are in 4c02?
4cO2??? I think you mean '4CO2. This is carbon dioxide. There are only two(2) elements in carbon dioxide, they are Carbon & Oxygen. However, in one (1) molecule of carbon dioxide there are three(3) atoms, they are 1 carbon and 2 oxygen ; designated by the 'CO2'. The prefix '4' indicates that there are 4 molecules of carbon dioxide. This means in 4CO2 there are 4 carbon toms and 8(4 x 2) oxygen atoms. The CO2 the atoms are chemically combined. However, the '4' indicates that the four molecules are not chemically combined with each other, but discrete particles. (molecules). NB . In atomic symbols a one letter symbol is always written as a capital letter 'C' (Carbon), not 'c' If an atomic symbol contains two letters e.g. iron (Fe) , then the first letter is always a capital letter and the second letter is always a small case letter.
How many NADH molecules are produced during complete breakdown of one molecule of glucose?
During glycolysis, 2 NADH molecules are produced. During the citric acid cycle, 6 NADH molecules are produced. Therefore, a total of 8 NADH molecules are produced during the complete breakdown of one molecule of glucose.
