The correct answer is C electron cloud.
Dalton said it was solid, Rutherford discovered nucleus and orbits like planets, Thompson had mass of negative material with positive "chips" in it
Oxidation reaction is used in redox reaction
Water has a molar mass of 18.015 g/mol . This means that one mole of water molecules has a mass of 18.015 g . So, to sum this up, 6.022⋅1023 molecules<span> of water will amount to 1 mole of water, which in turn will have a mass of 18.015 g . 2.7144moles H2O ⋅</span>6.022<span>⋅1023molec.1mole H2O =1.635⋅1024molec.</span>
