from theoretical yield. Through simple molar calculations‚ using the coefficients in the balanced chemical equation( CaCl2(aq) + 2NaOH(aq) Ca(OH)2 + CaCl2)‚ the limiting reagent could be determined from the volumes of reactants used. The number two to four tests turned out as expected‚ NaOH and CaCl2 respectively being the limiting reagents. In the second test‚ according to our calculations‚ the products should have completely reacted‚ leaving pure water after filtration. In the test‚ the addition

The principle of limiting reactants relates to this lab because the limiting reactant is the substance that is used up first in a chemical reaction. The amount of product was limited by that reagent. The excess reactants were considered to be the other reagents that were presented in excess of the quantity that was reacted with the limiting reagent. The theoretical yield was determined as the amount of product obtained when the limiting reagent was completely used. The limiting reagent was identified

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.

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
