    The Effect of pH Level of a Liquid on the Rate of Corrosion of Copper wire In this experiment‚ I will be testing the corrosion rate of copper wire after leaving them in different liquids with different pH levels. By doing so I will be able to determine which pH level corrodes copper the fastest. I will conduct this experiment by pouring 250mL of different liquids with different pH levels in cups‚ followed by an iron strip placed into the cup. A stopwatch will be timing how long it takes the iron

    Name : Andi Nadya Amanda Period : 4 Grade : 11 Enzyme Lab Report Question How heats effect the length of reaction time of an enzyme? Hypothesis I think the heat will make the length of reaction time of an enzyme become slowly. Heat is one of a way to denature the substrate. It means the heat will break down the structure of substrate in order the reaction of enzymes that we activated into it become slowly. Method for Collecting Data First I will record the length of reaction time
