    Normally one would expect to find slaters  under logs or concrete slabs in one’s garden. Under these large  objects‚ the sun cannot reach directly; therefore it is darker‚ damper  and colder than the surroundings. Nevertheless‚ in winter we do not  see woodlice crawling around very often‚ and‚ also at night‚ it may  actually be warmer under such objects‚ because it looses heat more  slowly‚ so I predict that the woodlice would prefer a dark‚ damp and a  temperature of around 15oC. (The ground temperature

    An Investigation into the Factors Affecting the Rate of the Reaction between Calcium Carbonate and Hydrochloric Acid A chemical reaction is the process by which atoms or groups of atoms are redistributed‚ resulting in a change in the molecular composition of substances. The reaction rate is how quickly a reaction occurs and this can be affected by four different factors: ¡¤ changing the surface area of any solids involved ¡¤ changing the concentration of reactants in solution ¡¤ changing the temperature

    The Effect of Varying Molecular Weights on the Rate of Diffusion of Substances August 22‚2012 ABSTRACT The effect of molecular weight on the rate of diffusion was verified by the 2 tests: the glass tube setup and the water agar-gel setup. In the glass tube setup‚ two cotton balls were soaked in the solutions of hydrochloric acid (HCl) and ammonium hydroxide (NH4OH) and were simultaneously placed on both ends of the tubing.NH4OH had a lighter molecular weight of 35 g/mole which diffused

The question being answered was what kind of effect the increase in concentration of Convollaria roots had on the rate of fermentation. The hypothesis was that the antimicrobial activities in Convallaria majalis’s roots would hinder the process of yeast fermentation because it will cause self- destruction or death in the microorganism

    ABSTRACT The effect of molecular weight on the rate of diffusion was measured using two tests namely: the glass tube test and the agar-water test. The set-up of the glass tube test used two cotton balls of the same size. One cotton ball is moistened with hydrochloric acid (HCl) and the other one is moistened with ammonium hydroxide (NH4OH). The two cotton balls were inserted in both ends of the glass tube. NH4OH which has a lighter molecular weight (35.0459 g/mole) diffused with a faster rate (dave=20
