Hi sorry to bother I know that you guys can only answer 3 questions per the ask questions so I was wondering if you could solve the following 3 for me please thank you
![### Thermodynamics and Chemical Reactions
#### Standard Enthalpy Change of Combustion
The following are chemical reactions with their corresponding enthalpy changes and explanations.
#### 1. Reaction: Hydrazine and Oxygen
\[
N_2H_4(l) + O_2(g) \rightarrow N_2(g) + 2 H_2O(l)
\]
In this reaction, liquid hydrazine (\(N_2H_4\)) reacts with gaseous oxygen (\(O_2\)) to form gaseous nitrogen (\(N_2\)) and liquid water (\(H_2O\)). The enthalpy change for this reaction (\( \Delta H \)) isn't given explicitly here but would typically be calculated based on the standard enthalpy of formation values for each substance.
#### 2. Reaction: Ethanol and Oxygen
\[
C_6H_6O(l) + 4 O_2(g) \rightarrow 3 CO_2(g) + 3 H_2O(l)
\]
In this reaction, liquid ethanol (\(C_6H_6O\)) reacts with oxygen (\(O_2\)) to produce gaseous carbon dioxide (\(CO_2\)) and liquid water (\(H_2O\)). This is a typical combustion reaction of ethanol.
#### 3. Reaction: Carbon Disulfide and Oxygen
\[
CS_2(l) + 3 O_2(g) \rightarrow CO_2(g) + 2 SO_2(g)
\]
Liquid carbon disulfide (\(CS_2\)) reacts with gaseous oxygen (\(O_2\)) to form gaseous carbon dioxide (\(CO_2\)) and sulfur dioxide (\(SO_2\)). This reaction involves a redox process.
#### 4. Combustion of Cyclohexane
The combustion reaction of cyclohexane (\(C_6H_{12}\)) is represented by the reaction:
\[
C_6H_{12}(l) + 9 O_2(g) \rightarrow 6 CO_2(g) + 6 H_2O(l)
\]
For this combustion reaction, the standard enthalpy change of combustion (\( \Delta H^0_{combustion} \)) of cyclohexane (\(C_6H_{12}\)) is](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F7c430cc2-4097-4d45-9871-f052d1dcc428%2Fa5699ddc-921d-46af-9667-4da651d2475e%2Fq65afqi_processed.jpeg&w=3840&q=75)
