Anna [14]4 years ago

Molecules are pure substances.  This is because a molecule has a set ratio of elements in order to make that compound have the same properties.


For example:

Water is H₂O.  Always.  There is no alternate water formula.

Sand however, is a mixture, who knows exactly what is in sand, and how much of it is in there.

What types of predictions can be made using the Periodic Table?
Andrej [43]
Periodic trends are specific patterns that are present in the periodic table that illustrate different aspects of a certain element, including its size and its electronic properties. Major periodic trends include: electronegativity, ionization energy, electron affinity, atomic radius, melting point, and metallic character. Periodic trends, arising from the arrangement of the periodic table, provide chemists with an invaluable tool to quickly predict an element's properties. These trends exist because of the similar atomic structure of the elements within their respective group families or periods, and because of the periodic nature of the elements.

What would happen if the earth magnetic field flips? <br><br> plz help
Mumz [18]

The end of the world as we know it could come in any number of ways, depending on who you ask. Some people believe global cataclysm will occur when Earth's magnetic poles reverse. When north goes south, they say, the continents will lurch in one direction or the other, triggering massive earthquakes, rapid climate change and species extinctions.

 

The most dramatic changes that occur when the poles reverse is a very large decrease of the total field intensity,

Earth's magnetic field takes between 1,000 and 10,000 years to reverse, and in the process, it greatly diminishes before it re-aligns. It's not a sudden flip, but a slow process, during which the field strength becomes weak, very probably the field becomes more complex and might show more than two poles for a while, and then builds up in strength and [aligns] in the opposite direction.
