Answer:
What is a formation reaction? it is when a mol of a product it is formed from its elements constituents
What is standard heat of formation? the standard heat of formation or formation enthalpy, it is the amount of energy necessary for produce a mol of the product when its elements constituent react.
What is a combustion reaction? It is when a hydrocarbon reacts with oxygen and produce water a carbon dioxide
What is standard heat of combustion? It is the amount of energy released during a combustion reaction, measuring per mass or volume unit
Explanation:
A example of formation reaction is:
2H2 + O2 =2H2O
I hope my answer can help you
Answer:
Yes, with change in humidity, enthalpy changes as well.
Explanation:
This can be explained by the given relation:
H =
where
H = enthalpy (in Btu/lb)
w = specific humidity (lb-water/lb-dry air)
= dry-bulb temperature (in )
The above relation clearly explains that if temperature does not vary, enthalpy is in direct proportion with the humidity.
So, any change in humidity results in a corresponding change in the enthalpy.
Answer:
B
Explanation:
From charles' law,
where v is volume and t is absolute temperature
- Hence that's it
Answer:
A Half Life
Explanation:
The half life is the time it takes for the substance to become reduced by half as a consequence of decay.
<u>Answer:</u>
0.800 moles of will be produced when 0.400 moles of react and are decomposed
<u>Explanation:</u>
The decomposition of (aq) ------> 2C2H5OH (aq) + 2CO2
¬moles of = 0.400 moles
Moles of produced will be calculated by the formula,
Moles of CO2 = 0.400 moles of
Substituting the values,
Moles of = = 0.400*2 = 0.800 moles
Therefore, 0.800 moles of will be produced when 0.400 moles of react and are decomposed
