Comparing the reaction rate of a solid chunk of a substance (like marble or zinc) versus its powdered form.
A table with three columns: What was done , Observations (what you saw), and Equations/Conclusions .
(turning limewater cloudy), and hydrogen by the formation of water droplets. prakticheskaia rabota 1 po khimii 11 klass novoshinskii
In the 11th-grade chemistry curriculum by Novoshinsky, Practical Work No. 1 typically focuses on the or the qualitative composition of organic substances , depending on whether you are using the general or organic chemistry focused program. Topic: Speed of Chemical Reactions
Demonstrating that increasing temperature typically accelerates the reaction. Catalysts: Using substances like manganese dioxide ( MnO2cap M n cap O sub 2 ) to speed up the decomposition of hydrogen peroxide ( H2O2cap H sub 2 cap O sub 2 Topic: Qualitative Composition of Organic Substances Comparing the reaction rate of a solid chunk
In some versions of the Novoshinsky program (specifically those focusing on organic chemistry early in the year), Practical Work No. 1 is "Determination of the Qualitative Composition of Organic Substances".
To experimentally study the factors that influence the rate of chemical reactions. Key Experiments: Catalysts: Using substances like manganese dioxide ( MnO2cap
Observing how varying the concentration of an acid affects the speed of gas evolution.
