Answer:
The element A is S (sulfur)
Explanation:
The elements for the 3erd period in the periodic table are Na, Mg, Al, Si, P, S, Cl and Ar.
The one that has 6 e⁻ in its valence shell is the S, because it is missing 2 e⁻ to reach the octet rule. 2 e⁻ to has the most stable noble gas conformation.
The IE of S = 3360 kJ/mol
It is a little lower than Cl because the electron is so far from the nucleus, that's why we have to apply a very low ionization energy to rip the electron off.
Answer: All options (I, II, III, IV, V)
Explanation: The answer is all options because they never reach equilibrium or intersect at a region as the both decrease at the same rate.
Answer:
1.32×10²⁵ atoms of sulfate are contained in 22 units of it
Explanation:
1 unit = 1 mol
Al₂(SO₄)₃ → Aluminum sulfate
As 1 unit = 1 mol, 1 unit has 6.02×10²³ atoms of aluminum sulfate.
Let's make a rule of three:
1 unit of Al₂(SO₄)₃ contains 02×10²³ atoms
Then, 22 units of Al₂(SO₄)₃ must contain (22 . 6.02×10²³) / 1 = 1.32×10²⁵ atoms
Hold on give me a moment to answer this for you.
Answer:
D=volume/mass
Explanation:
what is the mass divide the volume from the mass and that is the density
