Methane gas (CH 4) reacts with oxygen gas (O2) according to the equation below. CH4 +202 + CO2 + H20+ energy
This reaction releases 890 kJ of energy for every mole of methane consumed.
Part 1. Is this reaction endothermic or exothermic?
Part 2. What is the enthalpy change value for this reaction?
Part 3. Explain in terms of potential energy, which has more energy -the products or
the reactants. Explain your response.

The diagram below shows a cell placed in a solution.a cell is shown placed inside a beaker. it is labeled cell. the solution inside the beaker is labeled 40% salt solution and the solution inside the cell is labeled 20% salt solution.only water is allowed to move in and out of the cell. what will most likely happen to the cell? it will expand as water moves out of it. it will shrink as water moves out of it.it will expand as water moves into it. it will shrink as water moves into it.
