Explanation:
Answer:
iron(III) Thus, Fe2+ is called the iron(II) ion, while Fe3+ is called the iron(III) ion. This system is used only for elements that form more than one common positive ion. We do not call the Na+ ion the sodium(I) ion because (I) is unnecessary.

Answer:
5. gains two electrons.
Explanation:
In order to determine the most stable monoatomic ion of oxygen, we need to consider the octet rule: atoms will gain, lose or share electrons to complete their valence shell with 8 electrons.
Oxygen is in the Group 16 in the Periodic Table, so it has 6 valence electrons. Therefore, it will gain two electrons to have the electron configuration of the closest noble gas.
Answer:
CO₂. Option B.
Explanation:
We can use the Ideal Gases Law to solve this question
Formula: P . V = n. R . T
First of all, we convert the T° from °C to K
T°C + 273 → 0°C + 273 = 273K
Let's replace data: 15 atm . 0.7462 L = n . 0.082 L.atm/mol.K . 273K
15 atm . 0.7462 L / (0.082 L.atm/mol.K . 273K) = n
0.500 mol = n
These moles are the amount for 22 g of gas. Let's determine the molar mass to find out the gas → molar mass = g/mol
22 g /0.5m = 44g/mol
This molar mass corresponds to CO₂
