I believe it would be combustion because of the products CO2 and then C+2H2
Answer: 2800 g
Explanation:
According to avogadro's law, 1 mole of every substance weighs equal to molecular mass and contains avogadro's number 
of particles.
Given mass = 5 kg = 5000 g
1 mole of 
produces = 1 mole of 
50 moles of produces =
of
Mass of 
2800 g of is produced from 5.0 kg of limestone.
Fentanyl is an opoid used for the pain medication together with other medications for anesthesia. It is illegally used as recreation drug as it is mixed with heroine and cocaine. The side effects of this fentanyl include vomiting, constipation, sedation, decreased breathing, hallucinations etc. Fentanyl does not have any hydrogen bonds instead it has nitrogen bonds associated with benzene ring. It does not form molecules within its molecules but forms hydrogen bonds with the water molecule. The nitrogen and the oxygen present forms bonds with the hydrogen of the water molecule. As it forms hydrogen bonds with water it is soluble in water.
<u>Answer:</u> The 
of the reaction at given temperature is -12.964 kJ/mol.
<u>Explanation:</u>
For the given chemical reaction:
The expression of 
for the given reaction:
We are given:
Putting values in above equation, we get:
To calculate the Gibbs free energy of the reaction, we use the equation:
where,
= Gibbs' free energy of the reaction = ?
= Standard gibbs' free energy change of the reaction = 0 J (at equilibrium)
R = Gas constant = 
T = Temperature = ![25^oC=[25+273]K=298K](https://tex.z-dn.net/?f=25%5EoC%3D%5B25%2B273%5DK%3D298K)
= equilibrium constant in terms of partial pressure = 
Putting values in above equation, we get:
Hence, the of the reaction at given temperature is -12.964 kJ/mol.
