Answer:
132g/mol
Explanation:
The problem here is to find the molar mass of the compound in g/mol
To solve this problem, we simply sum the atomic masses of the atoms in the compound:
(NH₄)₂ SO₄:
Atomic mass of N = 14g
Atomic mass of H = 1g
Atomic mass of S = 32g
Atomic mass of O = 16g
So;
Molar mass = 2[(14 + 4(1))] + 32 + 4(16) = 132g/mol
If ion charges <u>decreases</u> then less attraction and energy <u>decreases</u>.
If radii <u>increases</u> then there is more distance , less attraction result of this energy <u>increases </u>
so energy increases as ion charges increases and radii decreases
D. The energy released or absorbed during the reaction
Answer: 15.83 mol
Explanation:
To convert from atoms to moles, we will need to use Avogadro's number.
Avogardo's number: 6.022×10²³ atoms/mol
Now, we know that there are 15.83 moles.
