Answer:
sodium ion
Explanation:
And, so if we gots a representation of Na+ , or Cl− , we know that for the sodium ion, while there are 11 charged nuclear particles (how do we know this?), there are 10 charged extranuclear particles, 10 electrons.

Answer:
Volume of the rock, V = 2 mL
Explanation:
It is given that,
Water filled in a graduated cylinder is 3 mL
She then drops a small rock into the cylinder and the water level rises to the 5 mL mark
We need to find the volume of the rock.
The volume of the rock is equal to the difference in volume mark. So,
V = 5 mL - 3 mL
V = 2 mL.
Answer:
2/6
Explanation:
In a balanced chemical equation as:
aA + bB → cC + dD
Where coefficients of reaction relates the number of moles of substances that are involved in the reaction. In the reaction:
Mg₃N₂(s) + 6H₂O(l) → 3Mg(OH)₂(s) + 2NH₃(g)
Per mole of Mg₃N₂(s) and per 6 moles of H₂O you will produce 3 moles of Mg(OH)₂(s) and 2 moles of NH₃(g).
To convert moles of H₂O to moles of NH₃ you can use:
X moles of H₂O ₓ (2 moles NH₃ / 6 moles of H₂O)
That means conversion factor to convert the number of moles of water to number of moles of ammonia is <em>2/6</em>.
<em>-It is important to say that obtention of conversion factor requires, in the first, the balanced chemical equation-</em>
