it is over 32 degrees Fahrenheit (freezing), and below 120 degrees Fahrenheit (boiling)
The answer is: B-It showed that atoms can be divided into smaller parts.
It showed that all atoms contain electrons.
Tomson concluded that atoms are divisible and that the corpuscles are their building blocks (atoms are made up of smaller particles).
J. J. Thomson discovered the electron in 1897.
His "plum pudding" model (1904) suggested: the electrons are embedded in the positive charge.
With this model, he abandoned his earlier hypothesis (the atom was composed of immaterial vortices).
Answer:
Explanation:
In this case, according to the Periodic table
there is 1g of hydrogen per mole. As we know that dihydrogen (H2) has two hydrogen atoms per molecule. So,there will be 2*1g hydrogen per mole=2g dihydrogen per mole.
If there is 2g dihydrogen per mole,and we have 4g,then we know that there is 2 mole dihydrogen in 4g.And for hydrogen there is 4 moles in 4g of hydrogen
