The topic is The Effect of Temperature on the Rate of Dissolving. In this experiment‚ the scientist will research how the temperature of water will affect the rate of dissolving of different chemical solutes. The independent variable in this experiment are the different types of solutes used and the different temperatures the solvent will be adjusted to‚ and the dependent variable is the amount of weight of the solvent after the solute has dissolved in it. The constants are the same cups used to

Heart Rate Anticipatory Response: Anticipatory heart rate is the rate that the heart reaches before the start of exercise. Your heart rate usually picks up as a result of the anticipatory heart-rate response‚ this happens before exercise. When thinking about exercising before actually starting‚ the nerves that release the chemicals that adjust your heart rate increase the heart rate. The body expects exercise and therefore prepares for the activity‚ increasing the amount of oxygen being delivered

Concentrations of HCl on the Rate of Reaction Between HCl and Sodium Thiosulfate Chemistry Lab report Aim: The aim of this experiment is to determine how concentrations of HCl acid affect the rate of reaction when reacted with Sodium Thiosulfate (Na2S2O3). This experiment would require measuring the mass of the reaction over a period of time to be able to determine the rate of the reaction. Safety Precautions: In this experiment‚ SO2 gas is produced from the reaction between Sodium Thiosulfate and HCl

Title: Rate of Photosynthesis Introduction: Photosynthesis occurs in plants where the light energy changes to chemical energy. This process occurs in the chloroplast of the plant cell in order to have gas exchange in the organism. Purpose: To measure the effect of light intensity on the rate of photosynthesis in the leaf cells. Hypothesis: The higher the concentration of the sodium bicarbonate solution‚ the faster the leaf of the plant will rise to the surface of the water in the beaker‚ the

increase the transpiration rate more than the others? Why? The transportation was increased mostly by the fan: 6.4 As it increased the respiration by transporting water away from plant. 4. Which species of plants that you tested had the highest transpiration rates? Why do you think different species of plants transpire at different rates? The plant that was observed with the highest rate of transportation is the rubber plant. Also‚ each plant species has a rate of transportation‚ good
