Question

Connie and Dwayne combine 78 g potassium with 36 g of water. Why would they expect the total mass of the product to be why?
GPT 3.5
Connie and Dwayne would not expect the total mass of the product to be 78 g + 36 g = 114 g. This is because when potassium reacts with water, it undergoes a chemical reaction that forms potassium hydroxide (KOH) and hydrogen gas (H2). The hydrogen gas is released as a product and does not contribute to the total mass. Therefore, the total mass of the product would be less than 114 g and would mainly consist of potassium hydroxide. The exact mass of the potassium hydroxide would depend on the extent of the reaction and any other side reactions that might occur.
