please answer! <3
btw.
1.energy input needed to break bonds of reactants
2.energy stored in chemical bonds
3.White phosphorus has a lower activation energy than red phosphorus
4.Products have higher chemical potential energy than reactants.
5.Higher activation energy results in a slower reaction rate.
drBob222 the assignment or grade itself is called a quick check calm down
XD lol first of all, thanks @ur mom, for the correct answers
Now, @DrBob222, you must be searching for these questions or something, because every question that says "quick check" you say that exact same thing...
Lets get this straight,
there is a certain school, where the assignments are sorted by what they are about or review:
Quick Check: a short, to the point assessment that gives questions that go over the topics in the lesson. It is provided to "Quickly Check" your understanding of the topics in the lesson
Quiz:longer than a Quick Check, but shorter than a test. same thing, except for a slightly higher grade.
Practice: not for a grade, but it helps to see what you do and don't understand in the lessons
@DrBob222, i suggest you CHECK YOURSELF BEFORE YOU WRECK YOURSELF, and don't ASSUME things.
thank you @ur mom!!!
@DrBob222, how about you just answer the question? it doesn't matter whether they have the answer or not, we are supposed to help. anyways, @urmom is 100% correct! thank you @urmom!
5/5 Thanks @ur mom
1. The phrase that defines activation energy is (d) Energy input needed to break bonds of reactants. To determine the activation energy of a reaction, you need to consider the energy required to break the bonds in the starting materials (reactants) before the reaction can occur.
2. The phrase that defines chemical potential energy is (d) Energy stored in chemical bonds. Chemical potential energy refers to the energy that is stored in the chemical bonds of a substance. This energy can be released or absorbed during a chemical reaction.
3. The correct statement that explains the difference between white and red phosphorus is (b) White phosphorus has a higher activation energy than red phosphorus. Activation energy is the energy required to start a chemical reaction, so a higher activation energy means more energy is needed to initiate the reaction. Therefore, white phosphorus requires more energy to react compared to red phosphorus.
4. The chemical potential energy in an endothermic reaction can best be described as (a) Products have higher chemical potential energy than reactants. In an endothermic reaction, energy is absorbed from the surroundings, which increases the potential energy of the products compared to the reactants.
5. Activation energy and reaction rate are most likely related in the following way: (a) Higher activation energy results in a slower reaction rate. Activation energy is the energy barrier that needs to be overcome for a reaction to occur. Higher activation energy means that more energy is required to initiate the reaction, resulting in a slower rate of reaction.
