True or False When the attraction between the particles overcomes their motion the particles clump together to boil. ​
bixtya [17]

Answer:

False

Explanation:

It is wrong to claim that when the attraction between particles overcomes their motion, the particles will clump together to boil.

During boiling particles do no clump together, they tend to move apart more rapidly.

  • Boiling occurs when the vapor pressure overcomes the ambient atmospheric pressure.
  • The hotter part of the boiler close the heat source moves rapidly away because they have become less dense.
  • The colder and denser part sinks and this interaction sets up a convection cell.

2 C2H6 + 7 026 H2O + 4 CO2
Kay [80]

Answer:

Oxygen is limiting reactant

Explanation:

Based on the chemical reaction:

2C2H6 + 7O2 → 6H2O + 4CO2

<em>2 mole of ethane reacts with 7 moles of oxygen</em>

<em />

For a complete reaction of 5.25 moles of ethane are required:

5.25 moles Ethane * (7mol Oxygen / 2mol Ethane) = 18.38 moles of oxygen

As there are just 15.0 moles of oxygen
