The answer to this question is option B. (I observed that butterflies prefer the yellow flowers.) The others are simply just opinions. Give me brainliest please :)
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.
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!

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>
