C3H8 + 5 02 — 3 CO2 + 4 H20 a. How many liters of propane(C3H8) will produce 5.67 liters of carbon dioxide?
b. How many moles of propane are needed to produce 5.67 liters of carbon dioxide?
c. What mass of propane is needed to produce 5.67 liters of carbon dioxide?

acid rain does not usually kill trees directly. instead, it is more likely to weaken the trees by damaging their leaves, limiting the nutrients available to them, or poisoning them with toxic substances slowly released from the soil. the main atmospheric pollutants that affect trees are nitrates and sulphates.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.

i think that the answer is c
