The answer is D. Effective collisions lead to chemical reactions!
If I remember correctly, you would have to heat the reaction beaker over a burner..
I apologize if I'm wrong
Answer:
C6H12O2 is the formula for Methyl pentanoate
Answer:
The assumptions of the Bohr model of the atom are:
- Atoms have a central nucleus with electrons in orbit about this nucleus.
- They must gain energy to jump to a higher level, and they release energy when jumping to a lower level.
- Electrons orbit the nucleus, but the orbits can have only certain sizes and energy values.
Explanation:
The Bohr model of the atom establishes that atoms have a central nucleus with positive charge and electrons (with a negative charge) in orbit about this nucleus. In the Bohr model, electrons move in specific orbits with a certain amount of energy and can't jump from one orbit to another around the nucleus. To jump to a higher level, they must gain energy or release energy when jumping to a lower level.
The Thomson model of the atom postulated that <em>atoms are solid spheres of matter</em> and <em>are made of positive material with electrons fixed in place in this positive material</em>.
