Answer:
Chlorine takes electrons from potassium in the reaction.
Explanation:
2K + Cl₂ ⟶ 2KCl
The KCl is an ionic solid.
It consists of K⁺ and Cl⁻ ions that are formed by the transfer of an electron from K to Cl.
The chlorine takes electrons from potassium, and Gain of Electrons is Reduction.
At the same time, potassium loses electrons to chlorine, and Loss of Electrons is Oxidation.
Both oxidation and reduction are occurring, so this is an oxidation-reduction reaction.
there would be 3.752*10^24 atoms in 100 grams of CH4
Steps:
CH4: 12.01+4(1.01)=16.05
100g/16.05 mol mass=6.23g/mol
6.23*6.02*10^23=3.75*10^24
Answer:
Robert Hooke
Explanation:
He saw a series of walled boxes that reminded him of the tiny rooms, or cellula, occupied by monks.
Molecular formula of sulfur trioxide is SO₃
Molar mass of SO₃ is - 32 + (16 x 3 ) = 80 g/mol
1 mol of any substance consists of 6.022 x 10²³ units. In 1 mol of SO₃ there are 6.022 x 10²³ molecules of SO₃
in 80 g of SO₃ - there are 6.022 x 10²³ molecules of SO₃
Therefore in 78 g of SO₃ - there are 6.022 x 10²³ /80 x 78 = 5.871 x 10²³ SO₃ molecules
