Let us assume propane was the fuel
C3H8(g) + 5O2(g) ---> 3CO2(g) + 4H2O(g) = 2217kJ
1 mole ofpropane produces 3 moles of CO2
heat absorbed by pork = 0.11 x 2217
= 243.87 kJ/mol
number of moles of propane = 1700kJ / 243.87 kJ/mol
= 6.971 moles
1 mole of C3H8 = 3 moles ofCO2
6.971 moles of C3H8 = ?
3 x 6.971 = 20.913 moles of CO2
Convert to grams
mass = MW x mole
= 44 x 20.913
= 920.172g of CO2 emitted
Answer:
I believe it is B (if you get it wrong it's my fault)
It would have to be carbon dioxide, the only gas listed. For gases, 1 mole of particles occupies 22.4 L of volume at STP.
Answer:
1. Yes it is balanced.
2. Water in its state change. It changes the T° from 90° to 100°C. The kinetic energy of the molecules will be higher when the temperature increases.
Explanation:
1. Mg + 2HCl → MgCl₂ + H₂
The equation is balanced, just see the subscript and the stoichiometry of the reaction
You have 1 Mg in both sides, 2 Cl in both sides and 2 H in both sides.
2. Let's use water as an example.
When water changes its temperature, from 90°C to 100°C, we say that is changing from liquid state to gas.
When you give "heat" to something you are modifying its temperature. In this case, this heat increase the temperature of water. Heat is a sort of energy. For this case, the kinetic energy of molecules is higher.
If you see water on a vessel about to boil, you will see particles rising from the bottom to the surface to pass into the gaseous state. If there is an increase in the kinetic energy in the molecules, it means that they will move more freely and much more quickly, so it will be easier for them to "escape" from the liquid phase to the gas phase.
