Answer: The enthalpy of combustion, per mole, of butane is -2657.4 kJ
Explanation:
The balanced chemical reaction is,
The expression for enthalpy change is,
Putting the values we get :
2 moles of butane releases heat = 5314.8 kJ
1 mole of butane release heat = 
Thus enthalpy of combustion per mole of butane is -2657.4 kJ
Parasitism... basically a tick and a dog. The dog is the host, which is harmed by the tick.
Is it multiple choice or anwser or each question
Answer:
The false statement is: 3. Because liquid water and liquid carbon tetrachloride do not mix, neither do their vapors
Explanation:
Gas is a state of matter, that has <u>less density than liquids and solids</u>. The gaseous particles have low intermolecular forces and thus they can move freely.
It is a very <u>compressible fluid</u> that has no fixed shape. Gas occupies the whole container in which it is stored, thus taking the shape of the container. Therefore, <u>the volume of the gas is equal to the volume of the container.</u>
<u>Polar liquid like water (H₂O) and nonpolar liquid like carbon tetrachloride, are immiscible. However, in the gaseous state, their vapors form a homogeneous mixture.</u>
