Oxyacetylene torches are fueled by the combustion of acetylene, C2H2.

2C2H2(g) + 5O2(g) --> 4 CO2(g) + 2H2O(g)

If the enthalpy change for the reaction is -2511.14 kJ/molrxn, how much heat can be produced by the reaction of

a. 2mol of C2H2?
b. 1 mol of C2H2?
c. .500 mol of C2H2?
d. .2000 mol of C2H2?
e. 10g of C2H2?

Can you help me set these up?

Of course! I'm more than happy to help you set up the calculations. Just remember, my specialty is humor, so I'll do my best to include some funny commentary along the way!

a. 2 mol of C2H2:
To calculate the heat produced, we need to multiply the number of moles of acetylene by the enthalpy change for the reaction.
Heat (kJ) = moles of C2H2 × enthalpy change
Heat = 2 mol × (-2511.14 kJ/molrxn)
Heat = -5022.28 kJ
Wow, that's quite a "hot" reaction if you ask me!

b. 1 mol of C2H2:
Similar to the previous example, we'll need to multiply the moles of acetylene by the enthalpy change.
Heat = 1 mol × (-2511.14 kJ/molrxn)
Heat = -2511.14 kJ
Let's hope things don't get too "heated" with just one mole!

c. 0.500 mol of C2H2:
You know the drill by now! It's time to multiply the moles of acetylene by the enthalpy change.
Heat = 0.500 mol × (-2511.14 kJ/molrxn)
Heat = -1255.57 kJ
Well, well, look at that! Half the moles, half the heat. A "half-hearted" reaction, if you will.

d. 0.2000 mol of C2H2:
Let's continue the trend and multiply the moles of acetylene by the enthalpy change.
Heat = 0.2000 mol × (-2511.14 kJ/molrxn)
Heat = -502.23 kJ
It seems like we're starting to "cool off" a little with this smaller number of moles.

e. 10 g of C2H2:
To handle this calculation, we'll need to convert grams to moles before proceeding. The molar mass of C2H2 is 26.04 g/mol, so:
moles of C2H2 = 10 g ÷ 26.04 g/mol ≈ 0.3842 mol
Now we can multiply the moles by the enthalpy change:
Heat = 0.3842 mol × (-2511.14 kJ/molrxn)
Heat ≈ -964.19 kJ
Well, that's certainly a "lit" result! But be careful not to let the heat get out of hand.

I hope these setups and my hilarious commentary brightened your day a bit! Let me know if there's anything else I can assist you with.

Sure! To calculate the amount of heat produced in each case, we can use the equation:

q = n * ΔH

where:
q is the heat produced in Joules (J)
n is the number of moles of acetylene (C2H2)
ΔH is the enthalpy change of the reaction in kJ/molrxn

To convert the heat from kJ to J, we need to multiply ΔH by 1000.

a. For 2 mol of C2H2:
q = 2 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
= -5022.28 kJ

b. For 1 mol of C2H2:
q = 1 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
= -2511.14 kJ

c. For 0.500 mol of C2H2:
q = 0.500 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
= -1255.57 kJ

d. For 0.2000 mol of C2H2:
q = 0.2000 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
= -502.23 kJ

e. For 10 g of C2H2:
To find the number of moles, we need to use the molar mass of acetylene (C2H2), which is:
C = 12.01 g/mol
H = 1.008 g/mol

Molar mass of C2H2 = (2 * C) + (2 * H) = (2 * 12.01 g/mol) + (2 * 1.008 g/mol) = 26.04 g/mol

Number of moles = mass / molar mass = 10 g / 26.04 g/mol = 0.384 mol

q = 0.384 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
= -967.11 kJ

So, the setups for the calculations are as follows:

a. q = 2 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
b. q = 1 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
c. q = 0.500 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
d. q = 0.2000 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)
e. q = 0.384 mol * (-2511.14 kJ/molrxn) * (1000 J/1 kJ)

Sure! To determine the amount of heat produced by the reaction, you need to use the stoichiometry of the balanced chemical equation and the given enthalpy change.

The enthalpy change (-2511.14 kJ/molrxn) represents the heat produced by the reaction per mole of C2H2. So, we can use this value as a conversion factor to calculate the heat produced for different amounts of C2H2.

Let's set up the calculations for each scenario:

a. To find the heat produced by 2 moles of C2H2:
Heat = -2511.14 kJ/molrxn * 2 mol C2H2
Note: The negative sign indicates that the reaction is exothermic.
Substitute the value:
Heat = -2511.14 kJ/molrxn * 2 mol C2H2 = -5022.28 kJ

b. To find the heat produced by 1 mole of C2H2:
Follow the same approach as in part a:
Heat = -2511.14 kJ/molrxn * 1 mol C2H2 = -2511.14 kJ

c. To find the heat produced by 0.500 mol of C2H2:
Heat = -2511.14 kJ/molrxn * 0.500 mol C2H2 = -1255.57 kJ

d. To find the heat produced by 0.2000 mol of C2H2:
Heat = -2511.14 kJ/molrxn * 0.2000 mol C2H2 = -502.228 kJ

e. To find the heat produced by 10g of C2H2:
First, convert grams of C2H2 to moles using the molar mass of C2H2 (26.04 g/mol).
Number of moles = 10 g C2H2 / 26.04 g/mol = 0.3844 mol C2H2
Now, multiply the number of moles by the enthalpy change:
Heat = -2511.14 kJ/molrxn * 0.3844 mol C2H2 = -965.48 kJ

Note: The negative sign in all the answers indicates that heat is released from the reaction.
