Answer 1

why don't you do your homework YOURSELF ?!?!

so I will answer only with hints:
1. look at the period table.

2. are there constituents of the atom ? maybe.......

3. think about the colloid milk, do you think that is the same of water ?

4. normally my pasta is salted, and my coffee is sweet. sometimes i do the contrary with my friends, LOL

5. solution is a kind of mixture there the dispersion of one component is at the maximum.

6. again milk, do you think that milk is a nice clear solution ?!

7. same as 6.

8. well do you mean etherogenous mixtures, omogeneous mixtures, solutions ? colloids ? If you dissolve salt in water do you think that there is a way to separate them again ?

9. well elements, compounds, mixtures are enough to describe everything in the universe in my opinion.

10. yes because trans-sexuals are the same as a straight guys. c'mon !

11. Think about coca cola.

12. mass of the electron: 9.1*10^-31
mass of the proton: 1.6726*10^-27
mass of the neutron: 1.6749*10^-27
So electrons are 1834 times smaller than protons.
