Answer:
The formula is H202 (hydrogen peroxide, known as hydrogen peroxide)
Explanation:
100%----34g
5, 9783%---X= (5, 9783%x 34g)/100% =2 g
1g---1 atom of H
2g----x= 2g x 1 atom of H/1g = 2 atom of H
100%----34g
94, 0217%---X= (94,0217%x 34g)/100% =32 g
16g---1 atom of 0
32g----x= 32g x 1 atom of 0/16g = 2 atom of 0
In the electron cloud model, the atoms are in unpredicted places. But in the Bohr model, atoms are in "rows"
Answer:
A galvanic cell is driven by the spontaneity of the chemical reaction occurring between the two compartments of the cell: Anode and Cathode.
Explanation:
A galvanic cell is driven by the spontaneity of the chemical reaction occurring between the two compartments of the cell: Anode and Cathode.
Note that the spontaneity of a reaction is either determined by its positive standard cell potential (
ξ
∘
) or its negative free energy (
Δ

).
<span>Option 4 is the correct answer. Rutherford concluded that the atom's volume was mostly empty space because the stream of alpha particles he directed at the gold foil arived at his detection aparatus mostly intact, indicating that relatively few of the alpha particles had been deflected. This follows because if the atom had not been empty space then the alpha particles would have encountered resistance and gone off course.</span>
