A calorimeter allows the exchange of energy but not matter.What is a System in Chemistry? The First Law of Thermodynamics states that the sum total of energy in the Universe is constant but changes forms. This law is the starting point for the topic of energy's involvement in chemistry. ...
The movement in response to a chemical is called chemotrophism. It is defined as the growth of an organism that is navigated by a chemical stimulus...Become a member and unlock all Study Answers Start today. Try it now Create an account Ask a question Our experts can answer your toug...
Different sorts of thermodynamic systems are there in nature. For example: open, closed and isolated systems. They differ from each other on the basis of exchange of heat and energy.Answer and Explanation: Thermodynamic system: It is nothing but a well-defined space where a chemical reaction ...
Chemical stoichiometry is discussed free from kinetic or thermodynamic considerations. The means for determining the following are presented: the number of stoichiometric degrees of freedom, the number of components, a permissible set of chemical equations, and a permissible set of components, for a cl...
However, some aspects of chemical bonding, including ionic bonding and intermolecular bonds other than hydrogen bonds remained problematic for students despite explicit teaching. The findings have implications for post-16 chemistry teaching, suggesting that a review of teaching strategies is needed in ...
What happens to a system in equilibrium when the forward and backward reactions are reversible? Which reaction - forward or backward stops?
What is Computational Fluid Dynamics (CFD)? Examples of Computational Fluid Dynamics How Computational Fluid Dynamics Works Challenges of Modeling Fluid Flow History of Computational Fluid Dynamics Governing Equations of CFD Advancements in CFD Learn More ...
The capability of online HPLC analysis of reaction mixtures is very useful in situations where in-situ spectroscopic measurements are less feasible due to overlapping spectral peaks or low concentration of key species. The authors report the development of a reaction monitoring system that draws a tim...
Cortisol, like all steroid-based hormones, is a powerful chemical. Steroid-based hormones have a common mechanism of action in that they enter cells and modify the gene activity in the DNA. The amount of cortisol in your body is driven by your eating patterns and how much physical activity ...
What is entropy? a. The amount of energy in a system b. The amount of disorganization c. The amount of organization Second law of thermodynamics: In all natural processes, the entropy of the universe increases. Therefore, regardless of the...
