Answer:
When energy is removed in liquid water then it will solidify since heat is given off by the system to its surrounding. It is an exothermic process where the enthalpy decreases since heat is taken off. So liquid water becomes ice in an exothermic process.
Explanation:
The chemical equation for the combustion of methane is CH4 + 2O2 --> CO2 + 2H2O.
The coefficients of that equation are 1, 2, 1, and 2, in the order you asked for.
1) ionic compound
there should be motive ions or free movable electrons to conduct electricity. The ionic compounds in the solid state, has no motive ions or free electrons as the ions are tightly attracted to each other. But in liquid state, the ions separate and move freely.
Answer:
Sodium hydroxide, a base, reacts with sulfuric acid to form sodium sulfate (complete neutralization) and water. If you write the balanced equation, you will see that 2 moles of sodium hydroxide react with 1 mole of sulfuric acid to form 1 mole of sodium sulfate and 2 moles of water. Therefore it would take .25 moles of sulfuric acid to react with .5 moles of sodium hydroxide.
