There are eight types of chemical reactions. These eight reactions are Decomposition‚ Composition‚ Acid/Base‚ Synthesis‚ Single-Replacement‚ Double-Replacement‚ Precipitation‚ and Redox. Though these eight could be referred to as the same due to them being chemical reactions. They are actually very different. An example of this difference is Decomposition and Synthesis. Decomposition is when a compound is broken into smaller chemical species while a Synthesis reaction is two or more chemical species

Aim During this experiment I will be investigating if heating limestone and changing the concentration of the acid will affect the rate of reaction. Preliminary work Before doing our main experiment‚ we will have to conduct another experiment‚ to see what concentration of acid we will have to use. We done this using 0.1M‚ 0.5M and 1M of Hydrochloric acid‚ and 0.1g of powdered limestone‚ we used powdered limestone‚ as it would be a fairer test‚ I think this as all the particles of limestone will

remains intact within the cell if the cells are not “stressed” by the external environment. In this exploration‚ two factors that affect the movement of the betalain out of the beetroot cells will be explored – surface area of the beetroot and the change in the external environment. I hypothesize that the 4ml of 50% alcohol in which the beetroot cells are submerged in would contain the most amount of pigments diffused from the beetroot cells.
