How many liters of methane gas (CH4) need to be combusted to produce 8.5 liters of water vapor, if all measurements are taken at

the same temperature and pressure? Show all of the work used to solve this problem. CH4 (g) + 2O2 (g) CO2 (g) + 2H2O (g)

1 mole of CH4 results to 2 moles of H2O.

If 8.5 liters are to be produced, then (1CH4/2H20)*(8.5L h2o) = 4.25L CH4

How to do you not fall in love with someone?
spin [16.1K]

Answer:

Self value and rational thinking.

Explanation:

If you don't want to fall in love with someone, list reasons as to why. Understand you're amazing and that you don't <em>need</em> to be with anyone. Self value is very important so you don't fall for people that you believe will support you better than you can.

Good luck! :]

The activation energy for the reaction NO2(g)+CO(g)⟶NO(g)+CO2(g) is Ea = 375 kJ/mol and the change in enthalpy for the reaction
HACTEHA [7]
Answer: 625 kj/mol

Explanation:

As shown below this expression gives the activation energy of the reverse reaction:

EA reverse reaction = EA forward reaction + | enthalpy change |

1) The activation energy, EA is the difference between the potential energies of the reactants and the transition state:

EA = energy of the transition state - energy of the reactants.

2) The activation energy of the forward reaction given is:

EA = energy of the transition state - energy of  [ NO2(g) + CO(g) ] = 75 kj/mol

3) The negative enthalpy change - 250 kj / mol for the forward reaction means that the products are below in the potential energy diagram, and that the potential energy of the products, [NO(g) + CO2(g) ] is equal to 375 kj / mol - 250 kj / mol = 125 kj/mol

4) For the reverse reaction the reactants are [NO(g) + CO2(g)], and the transition state is the same than that for the forward reaction.

5) The difference of energy between the transition state and the potential energy of [NO(g) + CO2(g) ] will be the absolute value of the change of enthalpy plus the activation energy for the forward reaction:

EA reverse reaction = EA forward reaction + | enthalpy change |

EA reverse reaction = 375 kj / mol + |-250 kj/mol | = 375 kj/mol + 250 kj/mol = 625 kj/mol.

And that is the answer, 625 kj/mol

Pls help!!! Write asap!! <br> How many moles of sulfur are there if you have 0.994g of sulfur
timama [110]

To convert weight to moles, we must use the molar weight found on the periodic table. Sulfur's (S) molar weight is 32.06 g/mol. Then we set up an equation and cancel out units:

\frac{1mole}{32.06g}*0.994g=0.031mol=3.1*10^{-2}mol

So now we know that 0.994g of sulfur is equal to 0.031 moles.
