What is the major difference between Glucose and fructose ?
It is there structures, which make them different molecules
What is 2 differences of crystals and polymers
Crystals have a 3D pattern and polymers have a repeating chain pattern. The second is they can have different atoms
C3H4 has how many elements? Atoms?
2 elements, 7 atoms
What is an element
A pure substance made of one type of atom
What is a molecule
It what makes up a molecule ( smallest unit of matter)
What is a molecule?
2 or more
atoms bonded together.
When making molecule models, what do the beads represent? The sticks?
The beads represents the atoms, and the lines are the bonds
Can you have two different crystals made of the same atom
Yes you can have turo
different crystals, an example is a Diamond and
Graphite. There Structure
is different but,
of the
Same atoms.
This
doesn’t mean
Overall there made
there the
as I said they have stuctural ditteraces.
same though
