Balance the equation.<br>P + 02 --&gt; P4O10​
charle [14.2K]

Answer:

4P + 5O₂ —> P₄O₁₀

Explanation:

From the question given above, we obtained:

P + O₂ —> P₄O₁₀

The above equation can be balance as illustrated below:

P + O₂ —> P₄O₁₀

There are 4 atoms of P on the right side and 1 atom on the left side. It can be balance by 4 in front of P as shown below:

4P + O₂ —> P₄O₁₀

There are 10 atoms of O on the right side and 2 atoms on the left side. It can be balance by putting 5 in front of O₂ as shown below:

4P + 5O₂ —> P₄O₁₀

Now the equation is balanced.

Are there moles of stars in the universe?
Natalka [10]

Answer:

Yes, a mole is defined as 6x1023 of something, so a mole of stars is 6x1023 stars. If we compare this number to our estimate of the total number of stars, we find that there is about 1/10 of a mole of stars in the Universe.

Hope this helps!

Consider the fructose-1,6-bisphosphatase reaction. Calculate the free energy change if the ratio of the concentrations of the pr
enot [183]

Answer:

ΔG = -8.812 kJ/mol

Explanation:

To obtain the free energy of a reaction you can use the expression:

ΔG = ΔG° + RT ln Q

<em>Where: </em>

<em>ΔG° is Standard Gibbs Free energy: -16.7kJ/mol = -16700J/mol</em>

<em>R is gas constant: 8.314472 J/molK</em>

<em>T is absolute temperature (37°C + 273.15 = 310.15K)</em>

<em>And Q is reaction quotient: 21.3</em>

<em />

Replacing in the formula:

ΔG = ΔG° + RT ln Q

ΔG = -16700J/mol + 8.314472J/molK*310.15K ln 21.3

ΔG = -8812.4J/mol

<h3>ΔG = -8.812 kJ/mol</h3>

<em />
