Answer:
0.054 moles of carbon dioxide will be produced
Explanation:
Step 1: Data given
Number of moles oxygen = 0.085 moles
Step 2: The balanced equation
2C8H18 + 25O2 → 16CO2 + 18H2O
Step 3: Calculate moles of carbon dioxide
For 2 moles octane we need 25 moles oxygen gas to produce 16 moles carbon dioxide gas and 18 moles water vapor
0.0544
For 0.085 moles O2 we'll have 16/25 * 0.085 = 0.054 moles CO2
0.054 moles of carbon dioxide will be produced
Co2(s). Co2 Solid Solids have definite shape and definite volume. This is because the particles that build up a solid are crammed in a fixed, closely packed geometric arrangement.
Fluids (gases or liquids) do not have definite shape and occupies the shape of the containers. While gases assume the volume of the container, liquids occupy part of it.In aqueous solutions, the particles lose their shape and volume and occupies the shape of its solvent (water). The volume is also modified accordingly. CO2(s) has definite shape and definite volume. and the correct answer would be Co2 solid.
