First let's look at the photosynthesis equation:
6CO₂ + 6H₂O --> C₆H₁₂O₆ + 6O₂
We know that:
CO₂ is carbon dioxide
H₂O is water
<span>C₆H₁₂O₆ is glucose
</span><span>O₂ is oxygen
</span>
We also know that the left side of the reaction is the reactants (which gets used up), and the right side is what is produced.
Now, we can look at each of the choices to see which one matches the equation:
We can eliminate the last two choices automatically because there is no hydrogen atoms present on either side.
The second one is not correct because oxygen is a product, not a reactant.
Therefore, the answer is the first one because carbon dioxide is a reactant, and oxygen is a product.
The answer to your question is DNA!!!!! :)
I believe propane burns to form water vapor and carbon dioxide
The overall reaction order is 2, because you add the orders of the individual components, which each are 1.
The balanced chemical equation that illustrates this reaction is:
<span>C2H4 + 3O2 --> 2CO2 + 2H2O
</span>
From the periodic table:
mass of carbon = 12 grams
mass of hydrogen = 1 gram
Therefore:
molar mass of C2H4 = 12(2) + 4(1) = 24 + 4 = 28 grams
number of moles = mass / molar mass
number of moles of C2H4 = 54.7 / 28 = 1.95 moles
From the balanced equation above:
3 moles of oxygen are required to react with one mole of C2H4, therefore, to know the number of moles required to react with 1.95 moles of C2H4, all you have to do is cross multiplication as follows:
number of oxygen moles = (1.95*3) / 1 = 5.85 moles
