Answer:
0.474 moles of C₆H₆OS
Explanation:
Step 1: Write the balanced equation
2 C₆H₆OS + 11 O₂ ⇒ 12 CO + 6 H₂O + 2 SO₃
Step 2: Establish the appropriate molar ratio
According to the balanced equation, the molar ratio of C₆H₆OS to SO₃ is 2:2.
Step 3: Calculate the moles of C₆H₆OS reacted if 0.474 moles of SO₃ are produced
We will use the previously established molar ratio.
0.474 mol SO₃ × 2 mol C₆H₆OS/2 mol SO₃ = 0.474 mol C₆H₆OS
Answer:
I think it mught be 12.9?
Pd has an
anomalous electron configuration. Write the observed electron configuration of
Pd.
1s^2 2s^2 2p^6 3s^2 3p^6 4s^2
3d^10 4p^6 4d^10
The electron configuration
shown above is the original configuration of Pd. Here is the anomalous electron
configuration.
1s^2 2s^2 2p^6 3s^2 3p^6 3d^10

Answer :
and are reactants.
and are products.
Explanation :
Balanced chemical reaction : It is defined as the reaction in which the number of atoms of individual elements present on reactant side must be equal to the product side.
In the balanced chemical reaction, the reactants and products are separated by right arrow.
The species present on the left side of the right arrow is the reactant and the species present on the right side of the right arrow is the product.
When ethanol react with oxygen gas then it gives carbon dioxide and water as a product.
The balanced chemical reaction will be:
In the given balanced reaction,
and are reactants.
and are products.
Answer:
The molar heat of combustion of hydrazine is -663.82 kJ/mole.
Explanation:
First we have to calculate the heat gained by the calorimeter.
where,
q = heat gained = ?
c = specific heat =
= final temperature =
= initial temperature =
Now put all the given values in the above formula, we get:
Now we have to calculate the enthalpy change during the reaction.
where,
= enthalpy change = ?
q = heat gained = 20.7444 kJ
n = number of moles fructose =
The molar heat of combustion of hydrazine is -663.82 kJ/mole.
