What chemical reaction occurs during the Breathalyzer?
During a Breathalyzer test, the chemical reaction that occurs is the oxidation of ethanol (alcohol) in the breath. The device typically uses an oxidizing agent, such as potassium dichromate, which reacts with the ethanol to produce acetic acid and chromium ions. This reaction changes the color of the solution, and the extent of the color change is proportional to the concentration of alcohol in the breath, allowing for the determination of blood alcohol content.
What represents the difference between the free energy content of hte reaction and the free energy content of the products?
The Gibbs free energy change (∆G) of a reaction represents the difference between the free energy content of the reactants and the free energy content of the products. A negative ∆G indicates that the reaction is spontaneous and can proceed without requiring external energy input.
How can you distinguish chemical limestone and dolostone?
Chemically, the distinction between limestone and dolostone is that the first one is chiefly composed of calcite, CaCO3, whereas the second is rich in MgCO3-Dolomite-. Therefore, the difference is limestone has Ca and Dolostone has Mg.Mg is replacing Ca in the dolostone, in other words.It is very difficult to make the distinction in a macro-scale samples. You will need optical or chemical procedures to differentiate each one.
What is the enthalpy of a reaction?
The amount of energy that is used or released as heat in a reaction.
What are two physical properties and two chemical properties of a bag of microwave popcorn before popping and after?
Two physical properties of a bag of microwave popcorn before popping are its mass and volume, which remain constant before and after popping. Two chemical properties that change after popping are the composition of the kernels, which undergo a chemical reaction to turn into fluffy popcorn, and the release of aroma compounds due to the Maillard reaction during popping.
What are two chemical reaction differences from each other?
The difference of two chemical reeactions may be its content and its resulting chemical substance. : )
What is the difference between enthalpy and heat of reaction in a chemical reaction?
Enthalpy is the total heat content of a system, including both heat absorbed and released during a reaction. Heat of reaction specifically refers to the heat released or absorbed when a specific chemical reaction occurs.
What is the difference between the heat of reaction and enthalpy in a chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction, while enthalpy is the total heat content of a system. Enthalpy includes the heat of reaction as well as any changes in pressure and volume.
How do you make a reaction paper?
To make a reaction paper, start by reading or watching the content you are reacting to. Take notes on your initial thoughts, feelings, and opinions. Then, organize your writing by summarizing the content, discussing your reaction and feelings towards it, and including supporting evidence or examples. Finally, conclude with a reflection on the overall impact or significance of the content on you.
What is the chemical term for heat transfer in a reaction?
The chemical term for heat transfer in a reaction is "enthalpy." Enthalpy is a thermodynamic quantity representing the heat content of a system and is often used to quantify the amount of heat released or absorbed during a chemical reaction.
How might enzymes influence the chemical reaction?
either through alkaline or acidic content in the enzyme or maybe salinity
How can you tell if a chemical equation is endothermic?
An endothermic reaction absorbs heat from its surroundings, causing a decrease in temperature. In a chemical equation, if the products have a higher energy content than the reactants, it indicates that the reaction is endothermic. This can be determined by examining the enthalpy change (∆H) of the reaction.
What is the best evidence for a chemical reaction?
ummm mabey look on another website or scroll down because guess what idkk haha homework stins:( hate techers cause they dont understand how friging busy people are being active duhh not sitting in a chair doing crap teachers are just idots we just pretend to like them well some not all ahah i promise hope this helped uuu love u <333 xoxox
What does a positive delta H tell about reaction?
A positive delta H indicates that the reaction is endothermic, meaning it absorbs heat from the surroundings to proceed. This implies that the products have higher energy content compared to the reactants.
How does a flameless ration heater work?
current field rations have a chemical substance in the lining of the food packet. by pouring a little water into the lineing of the packet the water is heated thus the food content is also heated.
What is the reaction to scoria when put in vinegar?
When scoria, a volcanic rock, is placed in vinegar (which contains acetic acid), it typically does not react significantly. Unlike limestone, which reacts vigorously with acids due to its calcium carbonate content, scoria is primarily composed of silicate minerals that are not affected by vinegar. As a result, there may be minimal bubbling or fizzing, but the overall reaction is negligible.
Potash in cooking?
The chemical name for potash is potassium carbonate. It is an alkaline salt used in many African dishes. It has been shown to increase the protein content and mineral content of such foods. Too much can cause a toxic reaction.
