when baking soda reacts with acetic acid from vinegar to form carbo dioxide and water the reaction mixture warms slightly, knowing this what statement is true the enthalpy of the products is less than the enthalpy of the reactions what statement best describes the flow of heat ...
EXP: water flows freely, honey doesnt flow as freely (honey's viscosity is 8,000 times greater than water, honey mostly consists of sugars with high molar masses and sugars can form H-bonds with themselves. water has low viscosity, low molar mass and can form H-bonds with itself) ...

In the third phase of Zimmerman’s model, the self-reflection phase, learners not only engage in self-evaluation (one form of self-judgment) of their laboratory experiences pertinent to SLI-based laboratory activities but also engage in self-reaction in a way that reflects on their feelings of...
The main topics in chemistry include atoms (the individual building blocks that make up matter), compounds (combinations of atoms that form more complex materials), and mixtures (combinations of compounds that form mixtures like air). What are examples of chemistry? Some chemistry examples in every...
Herein, redox-inactive Ti4+ is introduced to substitute partial Mn4+ to form Na2Ti0.5Mn2.5O7 (Na4/7[h1/7Ti1/7Mn5/7]O2, h for Mn vacancies), which can effectively restrain unfavorable interlayer gliding of Na2Mn3O7 at high charge voltages, as reflected by an ultralow-strain volume ...
