Investigation 3 Determine the Limiting Reagent Chemistry Investigation 3 Limiting Reagents Aim: To determine the limiting reagent in a reaction. Hypothesis: if the number of moles of the solutions added together equals the stoichiometry ratio in the balanced equation‚ then we would not expect a limiting reagent in the reaction. Independent variable: The number of moles of the reactants Dependent Variable: The limiting reagent Constant Variable: The volume of reactants added Equipment:

Title: Finding the Ratio of Mole of Reactants in a Chemical Reaction Purpose of Lab: To find the coefficients of two chemical reactants that appears in a balanced chemical equation using the continuous variations method. Pre Lab Questions: 1. 2AgNO3(aq) + K2CrO4(aq) → 2KNO3(aq) + Ag2CrO4(s) 2. There is enough to make a valid conclusion because‚ on the graph‚ one can clearly see that the two lines intersect. Thus‚ one can also determine the mole ratio. The mole ratio is approximately

Limit The Use of Technology Over the past several years’ technology has advanced significantly. Nowadays most everything we use is done by some form of technology. Several years ago‚ we didn’t even have cellphones or the Internet‚ now we have cellphones that can access the Internet. This generation has become so dependent with technology that it is actually beginning to harm most us‚ not help us.

Factors Limiting Photosynthesis The rate of photosynthesis increases with increasing light intensity. But too much light intensity can slow down the rate of photosynthesis because the light damages chloroplasts in the leaf. The higher the temperature the greater the rate of photosynthesis as photosynthesis is a chemical reaction and chemical reactions increase with temperature. But at temperatures above 40 C the rate slows down because the enzymes involved are destroyed

Sam (name changed to protect confidentiality) is a nine month old boy who was born at 26 weeks and diagnosed with chronic lung disease. He was sent home on 0.3 litres (L) of oxygen per minute with the view of gradually weaning this down as he grew stronger. When I joined the community nurse visiting Sam at home‚ he had been weaned down to 0.1L of oxygen per minute‚ so was now having his time on oxygen weaned down; from continuous oxygen eventually to none. The community nurses follow the trust’s
