Lab activity 1: Effect of temperature‚ concentration‚ and pressure on equilibrium Introduction Our ongoing discussion has been on systems at dynamic equilibrium: for a reversible reaction‚ the rate of the forward reaction is equal to the rate of the reverse reaction. What happens if equilibrium is disturbed? In this lab activity‚ we are going to examine the effect of changing reaction conditions on the position of equilibrium. Part I: Effect of temperature We will consider the equilibrium

amount of solute affect the time it takes for the solute to dissolve?” I thought about this question for a very long time and come up with a hypothesis for the investigation was “If the amount of solute increases‚ then the time for the solute to dissolve will increase. This is because the solute will become more concentrated and it won’t disolve into the solvent as fast. (Sadner‚ 2008)” Looking at the data I collected‚ I think that this hypothesis was accepted‚ because the more solute added‚ the

1. Explain the relationship between the skeletal and muscular systems. The relationship between the skeletal and muscular systems is that we are made up of bones all throughout our body and we need this to stand and hold our body together‚ similar to the skeletal system the muscular system is made up of soft tissue and is lined all over our body. We could not stand without the system as well. 2. Why is the circulatory system important? This system is important because it is used to circulate blood
