D. Since it's atomic # is 14 it has 14 electrons and it has 4 valance electrons because it is 4 over.
Answer:
We can say, there are 4 mol of oxygen with (4 . NA) = 2.40ₓ10²⁴ atoms
Or just, 4 atoms oxygen.
Explanation:
CH₄ + 2O₂ → CO₂ + 2H₂O
1 mol of methane reacts with 2 mol of oxygen to produce 1 mol of carbon dioxide and 2 mol of water.
We count in 1 mol of CO₂, we have 2 mol of oxygen
In 2 mol of water, we have 2 mol of oxygen.
We can say, there are 4 mol of oxygen with (4 . NA) = 2.40ₓ10²⁴ atoms
Or just, 4 atoms oxygen.
0.11 moles of Aluminium chloride
<u>Explanation:</u>
<u />
Given:
2Al + 3Cl₂ → 2AlCl₃
According to the balanced equation:
2 moles pf Aluminium form 2 moles of Aluminium chloride.
So, 1 mole of Al will form 1 mole of Aluminium chloride.
0.11 mole of Al is present.
So, 0.11 mol of Al will form 0.11 mol of Aluminium chloride.
The earth revolves around the Sun, which is at the centre of our solar system. The moon revolves around the earth as a natiral satellite.

Answer:
The plateaus or horizontal lines on the graph represent the transition between states of the sample. The first plateau represents the melting (or transition from solid to liquid) and the second plateau represents boiling (or transition from liquid to gas).
