Answer:An atom
Explanation:
Because molecules more spread out and have things that connnect them and are not bunched up togoether
And Atoms are all packed up like in the picture
Hope this helps!:D
Answer:
1.024 x 10⁻²²g
Explanation:
Data Given:
mass of copper = 63.5 g
no. of atoms of copper = 6.02 x10²³ atoms
mass of of an average copper = ?
Solution:
As 6.02 x10²³ atoms have 63.5 g of mass then what will be the mass of atom.
Apply unity formula
63.5 g of copper ≅ 6.02 x10²³ atoms of copper
mass of copper atom ≅ 1 atom of copper
Do cross multiplication
mass of copper atom = 1 atom x 63.5 g / 6.02 x10²³ atoms
mass of copper atom = 1.024 x 10⁻²² g
mass of an average copper atom = 1.024 x 10⁻²² g
PH= pKa + log( conjugate base/ conjugate acid)
There are two main problems to overcome before fusion can produce energy:1) it must be able to achieve high enough temperatures to start the reaction.
2) Must contain plasma.
