Does anyone have the answers to the Energy in chemical reactions I unit test

Could you post the first question so I know I'm giving the answers to the right test.

My best guess is "not very often".

Hey, some of us just come on here for actual help when needed and I do my work by myself I come on here most of the time because I'm bored or I really need help.But yeah I think most people don't do their work.

The first question for me was "which of the following equations shows a chemical change?" I need help on this quiz still of you can

As an AI, I don't have access to specific unit tests or their answers. However, I can explain how to approach energy in chemical reactions and provide some general guidance on studying for your test.

To prepare for your Energy in Chemical Reactions I unit test, it's helpful to review the key concepts related to energy changes in chemical reactions. Here are some important topics you should study:

1. Overview of Energy Changes: Understand that energy is neither created nor destroyed in a chemical reaction but is only transferred or converted between different forms (such as heat, light, or electrical energy).

2. Exothermic and Endothermic Reactions: Learn the difference between exothermic reactions (releases energy to the surroundings) and endothermic reactions (absorbs energy from the surroundings). Familiarize yourself with examples of each type and understand the energy profiles of these reactions.

3. Heat Transfer: Gain knowledge about how energy transfers as heat during reactions and how to calculate the amount of heat released or absorbed using the equation: q = m × c × ΔT, where q represents heat energy, m is mass, c is specific heat capacity, and ΔT is the change in temperature.

4. Enthalpy: Understand the concept of enthalpy (H) as a measure of the heat content of a system. Learn about the difference between the enthalpy of reactants and products in a reaction and how to calculate the change in enthalpy (ΔH) by subtracting the enthalpy of the reactants from the enthalpy of the products.

5. Hess's Law: Familiarize yourself with Hess's Law, which states that the enthalpy change of a reaction is independent of the pathway taken from reactants to products. Learn how to use the enthalpy changes of known reactions to calculate the enthalpy change of an unknown reaction.

To obtain the specific answers to your unit test, it's best to consult your textbook, course materials, or reach out to your teacher or classmates for guidance.

Does anyone at connexus ever actually do their own work?

What a nest of cheaters!
