What is the difference between a molecule and compound?
A compound is a special type of molecule where the atoms that form the molecule are of different elements.
Determine mass contribution for the following isotopes of the same element.
At the end, tell me the atomic mass of the element using the mass contributions.
Do not forget your units or the question will be marked incorrect.
Isotope 2 amu: 186.956
percent abundance: 62.6%
Atomic Mass of the element ?
Answer: Not possible to find average amu with only the information provided.
Explanation:
Is there more information about the other isotopes? I don't see how one could calculate an overall atomic mass with only one isotope is known. An isotope of 186.956 with abundance of 62.6% isn't enough information. We're not told anything about the other isotopes: are they larger, smaller, and at what percentage. If one has an amu of 204.956 at 37.4%, the overall atomic mass would be quite different than if it had an atomic mass of 182.956 at 37.4%. More infornmation is required.

(D a blender mixing solid food into a paste)
Answer:
B. Saliva breaking down molecules in the mouth
Explanation:
I'm pretty sure it's this because saliva contains enzymes and enzymes use chemicals to break down food in your mouth. For example, your mouth has an enzyme called amylase which helps to break down starches.

Fossil fuels—such as coal, oil, and natural gas—come from ancient, and long dead, plant and animal matter. These fuels have been generated through millions of years of the Earth's geologic processes. Most fossil fuel reserves are found underground, relatively close to the Earth's surface.
At the current rate that human civilization is burning fossil fuels for energy, the Earth's geologic processes have no chance of keeping pace. This means that fossil fuels are a _______ energy resource.
A.
synthetic
B.
nonrenewable
C.
plentiful
D.
renewable
Answer:
Nonrenewable
Explanation:
There is a finite supply of fossil fuels
when using a ph meter to monitor a stirring reaction mixture, where should you place the ph sensor electrode?
Answer:Between the stirring vortex and the side of the glassware
When using a ph meter to monitor a stirring reaction mixture, the ph sensor electrode
should be placed;
between the stirring vortex and the side of the glassware.
The pH meter is an electric device that is used to measure the hydrogen-ion activity in water-based solutions. This means that it is used to measure the PH which is the acidity or alkalinity.
The pH meter is made up of a voltmeter attached to a pH-responsive electrode and a reference electrode.
Now, this pH-responsive electrode is usually made of glass while the reference electrode is usually a silver–silver chloride electrode.
Now when monitoring the stirring reaction mixture, the PH-responsive electrode written above is usually placed between the stirring vortex and the side of the glassware.

Is carbon mixed with sand a homogeneous or heterogeneous mixture
Answer:
homogeneous
Explanation:
because I said so
A carbon mixed with sand is a heterogenous mixture.
What is heterogenous mixture?
Mixture is defined as a combination to two or more simpler substances.
There are two types of mixture
Homogenous mixture - A homogenous mixture is defined as a mixture of two or more component which is uniform throughout the mixture. They include water, air, steel etc.Heterogenous mixture - A heterogenous mixture is defined as a mixture of two or more phase which is not uniform throughout the mixture. They include sand and water, salt and oil etc. They are a non uniform mixture with visible or invisible particles.Thus, carbon mixed with sand is a heterogenous mixture.

Physical Models Activity (I need help)
You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:
✔ Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
✔ Models must be created by you, not something selected from an online or outside source.
✔ Submit a presentation, picture, video, or screenshot of your model.
✔ Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.
Conservation of Mass
Atomic Theory
Thermal Energy
The question above wants to assess your ability to create a model to represent a scientific concept. In that case, I can't create the model for you, but I'll show you how to create that template.
First, you must choose one of the topics presented in the question. I suggest that you choose the topic "Conservation of Masses," because of its simplicity, however you should choose the one you are most familiar with.
Next, you should research this topic and look at the factors that make it up.
After that, you can create your template as follows:
Use a software that has ready-made drawings, mainly geometric figures, for you to represent the elements that make up this topic.Use these drawings to represent these elements, place titles that identify them, and add arrows, which direct the viewer's attention to understand the model.You can see examples of "Conservation of Masses," models in the attached figure.

Max Plank created the idea of quanta4 or quantum energy. This is?
Answer:
A theory of physics in which energy exists only in discrete quantities, called quanta. It was originated in 1900 by the German physicist Max Karl Ernst Ludwig Planck (1858–1947), who suggested that electromagnetic radiation is quantized, i.e. it can be emitted or absorbed only in tiny packets, not continuously.
