Answer:Heat is a type of ENERGY. When absorbed by a substance, heat causes inter-particle bonds to weaken and break which leads to a change of state (solid to liquid for example). Heat causing a phase change is NOT sufficient to cause an increase in temperature.
Explanation:
Answer:
x = 4.5
4.5 moles of C2H6 is required to produce 13.5 moles of H2O
Explanation:
Given equation is :
2 C2H6 + 7 O2 → 4 CO2 + 6 H2O
if it requires 2 moles of C2H6 to produce 6 moles of H2O
then x moles of C2H6 is required to produce 13.5 moles of H2O
Using unitary method for solving, we get
x = 13.5 x 2 / 6
x = 13.5 / 3
x = 4.5
Therefore, 4.5 moles of C2H6 is required to produce 13.5 moles of H2O
