laila [671]4 years ago
5 0
<h3>Answer:</h3>

C₅H₁₂O(l)+15/2O₂(g)→5CO₂(g)+6H₂O(l)

<h3>Explanation:</h3>

The balanced chemical equation for the combustion of the hydrocarbon in question is;

C₅H₁₂O(l)+15/2O₂(g)→5CO₂(g)+6H₂O(l)

  • A balanced chemical equation is one in which the number of atoms of each element is equal on both sides of the equation.
  • In this case;
  • Reactant side has; 5 carbon atoms, 12 hydrogen atoms and 16 Oxygen atoms
  • Product side has; 5 carbon atoms, 12 hydrogen atoms and 16 Oxygen atoms
  • An equation is balanced by putting appropriate coefficients on reactants and products involved in the reaction.
  • An equation is balanced so as to obey the law of conservation of mass.

Calculate the wavelength and frequency of an emitted photon of gamma radiation that has energy of 3.02 × 1011 J/mol.
maks197457 [2]

The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1

Using the formula;

E =hf

Where

E = Energy of the photon

f = Frequency of photon

h = Plank's constant = 6.6 * 10^-34 Js

To obtain the energy in Joules;

E = 3.02 × 10^11 J/mol/6.02 * 10^23 mol

= 5 * 10^-13 J

f = E/h

f = 5 * 10^-13 J/6.6 * 10^-34 Js

f = 7.5 * 10^20 s−1

f = c/λ

c = speed of light = 3 * 10^8 m/s

λ = c/f

λ =  3 * 10^8 m/s/7.5 * 10^20 s−1

λ =  4.0 * 10^-13 m

The wavelength is 4.0 * 10^-13 m while the frequency is 7.5 * 10^20 s−1

Which of the following statements is correct about the gases which participate in photosynthesis?
antoniya [11.8K]
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.
