Liver contains a enzyme called catalase. When hydrogen peroxide (H2O2) is added to liver, a chemical reaction occurs which results in the production of oxygen gas (O2) and liquid water (H2O).
Hope I helped
The answer I believe would be talking to plants may or may not helps plants grow faster because the amount of water given was likely different for each group. I say this because there are more than one manipulated variables. (Each experiment should only have one manipulated variable to really be able to come to a conclusion) The student wants to see if talking to the plant will help. But the student also used different watering methods. So there was more than one manipulated variable. This can not give a good enough result because we do not know which affected the plant- the talking or the watering method/amount.
Hope this helps!

Plating is a producing procedure wherein a skinny layer of steel coats a substrate. this may be achieved via electroplating, which calls for an electric current, or via electroless plating, which is in the autocatalytic chemical method.
The two techniques have different effects. Coating involves the usage of paint, like a powder-lined end. The process of plating, mainly “electroplating,” includes passing cutting-edge through an electrolyte. It splits and deposits atoms on metallic objects, making them electroplated.
Like plating, the coating is applied to metallic surfaces for protective functions. however, unlike electroplated surfaces, powder-lined surfaces are basically blanketed in paint – not steel.
The plating procedure is a submit-manufacturing system. It involves the coating or overlaying of the surface of a workpiece with a skinny layer of metallic. The simple know-how of Plating to have a thin layer of one steel coating a substrate. therefore, the aim is to enhance the general quality of the product.
