What mass (in g) of potassium chlorate is decomposed if the yield of oxygen gas for the first reaction is 88.6%, if it is known that all produced oxygen was used to make 23.6 g of carbon dioxide and the yield of the second reaction is 77.8%. Methane (CH4) is in excess. Enter a number in g to 1 decimal place. 2 KClO3 ⟶ 2KCl + 3O2 88.6% CH4 + 2O2 ⟶ CO2 + 2H2O 77.8%

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.
