Explanation:
Answer:
reduced
Explanation:
To win the metallic product from the oxide, it demands that the metal be reduced.
During reduction a metal will:
- gain electrons.
- there would be removal of oxygen from the specie
- there would be decrease in oxidation number of the atom
- decrease in the number of electronegative atom surrounding the element.
The specie that is reduced will become the oxidant and reducing agent in the chemical reaction.
Answer:
A
Explanation:
When the particles where shot through gold foil, he found that most of the particles went through. Some scattered in various directions, and a few were even deflected back towards the source.
Answer:
8 electrons
Explanation:
The second principal energy level has two sublevels: 2s and 2p
2s : 2 electrons
2p : 6 electrons (3 sublevels × 2 electrons each = 6 electrons)
It can hold a maximum of 8 electrons.

Molar mass methane ( CH₄) = 16.04 g/mol
number of moles:
mass CH₄ / molar mass
8.67 / 16.04 => 0.5405 moles
1 mole ------------------ 22.4 L ( at STP )
0.5405 moles --------- ??
0.5405 x 22.4 / 1 => 12.1072 L
hope this helps!
