Create a balanced equation of this combustion reaction: c8h18 (hint, all combustion reactions have some things in common (co2 and h2o). show all work leading up to balanced equation, step by step, including a scoreboard that shows individual atom count before and after. (reactants in green and products in red)

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.
