Chris is correct because the reactants and products do not have to have the same mass, but they do have to weigh the same. Is the correct answer:) Hannah is right because the mass of the reactants was different than the mass of the products. is incorrect
The answer is van der Waal force, or to be precise, London dispersion forces.
This type of force is present between all molecules and they are caused by electrons that are orbiting the atom cores. The moving of the electrons can result in making the atom temporary dipole due to the asymmetry of electron distribution around the core. This temporary dipole now can interact with other atoms leading to an electrostatic interaction. The more electrons an atom has, the stronger are these intermolecular forces.
Answer:
It is true that a characteristic of rock is that each of the component minerals retains its properties in the mixture.
Explanation:
Rocks are composed of two or more minerals. A rock is any naturally occurring solid mass or aggregate of minerals or mineraloid matter.
These minerals have been
1) cemented together
2) squeezed and heated together, or
3) melted and cooled together.
One of the most common rock is granite. The four minerals that make up granite are feldspar, quartz, mica, and hornblende. Each of these minerals retain their property in a mixture form in a rock.
