What is your question I can answer it
Answer:
50?
I think but not 100% sure if not lmk
Answer: Option (b) is the correct answer.
Explanation:
The elements which have excess or deficiency of electrons will react readily.
Atomic number of Mn is 25 and electronic configuration of is [Ar]. This configuration is stable.
Atomic number of Cr is 24 and electronic configuration of is [Ar]. This configuration is not stable.
Atomic number of Fe is 26 and electronic configuration of is [Ar]. This configuration is stable.
Atomic number of Cu is 29 and electronic configuration of is [Ar]. This configuration is not stable.
Atomic number of Al is 13 and electronic configuration of Al is . This configuration is not stable.
Atomic number of Ba is 56 and electronic configuration of is [Kr]. This configuration is stable.
Atomic number of Mg is 12 and electronic configuration of is . This configuration is stable.
Atomic number of Sn is 50 and electronic configuration of Sn is [Kr]. This configuration is stable.
Thus, we can conclude that out of the given options, only Fe and reactants would lead to a spontaneous reaction as they have incomplete sub-shells. Therefore, in order to gain stability they will readily react.

Explanation:
here is your answer to you work plz rate me the most brainlest
Answer:
292.4 g
Explanation:
- 2Al + 3H₂SO₄ → 3H₂ + Al₂(SO₄)₃
First we <u>convert 53.7 g of Al into moles</u>, using its<em> molar mass</em>:
- 53.7 g ÷ 27 g/mol = 1.99 mol Al
Then we <u>convert Al moles into H₂SO₄ moles</u>, using the <em>stoichiometric coefficients</em>:
- 1.99 mol Al * = 2.98 mol H₂SO₄
Finally we <u>convert 2.98 moles of sulfuric acid into gram</u>s, using its <em>molar mass:</em>
- 2.98 mol H₂SO₄ * 98 g/mol = 292.4 g
