Rutherford came to this conclusion after his Gold-Foil experiment. He found that most of the alpha particales(when released) went straight through the gold foil, of which consisted of atoms. In the middle of the atom theres a small nucleus that has mass and positive charge. Because the nucleus is so small the alpha <span>particles were able to go straight through leading to the conclusion that atoms are mostly empty space. </span>

Answer:
The water of crystallization for the formula of the unknown hydrate is 2.
Explanation:
Mass of an unknown hydrate = 1.000 g
Molar mass of hydrate = 195.5 g/mol
MOles of unknown hydrate =
Mass of hydrate after heating = 0.781 g
Mass of water lost due to heating = x
Moles of water lost =
1 Mole of hydrate has x moles of water and 0.00512 moles of hydrate has 0.0122 moles of water then we can write:
The water of crystallization for the formula of the unknown hydrate is 2.
To answer this question I would have to know the elements in the compound
