I was provided with a solution of a monobasic (monoprotic) acid. Monoprotic acid is an acid that contains only one hydrogen atom. I was to determine the molarity of the acid by titration with a sodium hydroxide solution, and then use this molarity to calculate the relative formula mass of the acid. An acid is […]
Read moreI am going to investigate the effects of changing the spinners speed on the drag. There are several variables that I could investigate to see their effects on the spinners drag. 1. Shape- I could alter the shape of the spinner 2. Size- I could investigate the effects on drag with different sizes of blade […]
Read moreThe experiment consisted of recording the results of a small toy car being allowed to roll down a ramp and then leave the end of the ramp by continuing straight off the drop from the end of the desk.

Read moreOur objective is to assess the quantity, variety, and environmental impacts on various plant species in two coppiced regions within Nower Wood. One of these areas underwent its last cutting three decades ago, whereas the other was more recently cut just seven years ago. The hypothesis proposes that the older coppice will have more plant […]
