Does anyone have the energy conservation quick check answers?

1) Freezing is exothermic because as water bonds into ice, the energy from bond formation is released and heats up the surrounding environment.

2) When a fire is burning, chemical energy is turned into visible energy in the form of light and thermal energy in the form of heat.
3)A burning fire is exothermic because a lot of heat is given off as the wood is converted into carbon dioxide and water.
4) Energy is never created but simply recycled and changed into other forms.
5) all parts combined

I just took it and well I was looking for the answer just like ya are and I came across this site and well I was not happy that there were no answers to the check so I have to do onto others that you would want to be done onto you so your welcome. I would like lots of thumbs up in the replys as thanks.

Everything was correct except 5 for me the correct answer is, The gasoline and spark.

Much thanks to ty bone though

your welcome

100% thank you

1. Freezing is Exothermic because as water bonds into ice the energy from bond formation is released and heats up the surrounding environment.

2. When fire is burning, chemical energy is turned into visible energy in the form of light and thermal energy in the form of heat.
3. A burning fire is exothermic because a lot of head is given off as the wood is converted into carbon dioxide and water.
4. Energy is never created but simply recycled and changed into other forms.
5. The gasoline and spark.

Why is mine so different? 💀uhhh what the heck

What does the Law of Conservation of Mass state?
1.) Matter is neither created or destroyed in a chemical reaction, only rearranged.
2.) The total mass of reactants prior to a chemical reaction is greater than the mass of the product due to the release of energy.
3.) The total mass of all of the reactants prior to a chemical reaction must equal the total mass of all the products after the reaction.
4.) Matter cannot be rearranged during a chemical reaction.

If the mass of elements before a chemical reaction is 30 grams, after the chemical reaction, the mass will be ___.
1.) 30 grams
2.) 28 grams
3.) 0 grams
4.) 32 grams

78g of potassium (K) react with 71g of chlorine (CI) to produce potassium chloride. According to the Law of Conservation of Mass, what is the mass of the product (2KCI)?
1.) 156g
2.) 2g
3.) 149g
4.) 4g

2 grams of potassium (K) reacts with 5 grams of Oxygen (O). According to the Law of Conservation of Mass, how many grams of potassium oxide (K2O) will be produced?
1.) 5 grams
2.) 7 grams
3.) 10 grams
4.) 2 grams

Which of the following equations demonstrates the Law of Conservation of Mass?
1.) CH + O2 —> CO2 + H2O
2.) CH4 + O2 —> CO2 + HO
3.) CH4 + O2 —> C + 2H2O
4.) CH4 + O2 —> CO2 + H2O

As an AI, I don't have access to specific assignments or answer keys. However, I can certainly help you understand the concept of energy conservation and guide you on how to approach a quick check on this topic.

Energy conservation is the principle that states energy cannot be created or destroyed, only transferred or transformed from one form to another. In the context of a quick check or assignment, the questions will likely focus on understanding and applying this principle in various scenarios.

To find the answers to your energy conservation quick check, you'll need to apply the following steps:

1. Review your course materials: Start by revisiting your textbook, lecture notes, or any other resources provided by your teacher. Pay attention to the definitions, formulas, and concepts related to energy conservation.

2. Analyze the question: Read each question carefully, identifying any specific variables, units, or given information provided in the question. Understand what is being asked before attempting to answer it.

3. Apply the conservation of energy principle: Use the knowledge you have gained about energy conservation to analyze the scenario or problem presented in the question. Identify the forms of energy involved (e.g., kinetic energy, potential energy), and determine their initial and final values.

4. Use relevant formulas: For example, if the question involves kinetic energy, use the formula KE = 1/2mv², where KE represents kinetic energy, m is the mass of the object, and v is its velocity. Make sure you understand and choose the appropriate formula based on the given situation.

5. Perform calculations and solve: Plug in the given values into the appropriate formulas, perform any necessary calculations, and obtain your answer.

6. Double-check your work: Once you have your answer, review your solution to ensure it makes logical sense and that you have used the correct units and calculations.

Remember, understanding and applying the concept of energy conservation is more important than simply having the correct answers. If you're still having trouble, I would recommend reaching out to your teacher, classmates, or tutoring resources for additional help and clarification.
