2 mol Al - 3 mol H₂SO₄
5 mol Al - x mol H₂SO₄
x=5*3/2=7.5
n(H₂SO₄)=7.5 mol
The correct option is ARGON.
To quickly find out the element that is been described by the electronic configuration, write down and add together all the index figures in the electronic configuration. The index figures in the above electronic configuration are 2, 2, 6, 2 and 6. If you add all these figures together, you will get 18 and the element that has the atomic number of 18 is argon.
The balanced nuclear equation for the reaction is
<h3>²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm + ⁷⁸₃₀Zn + 3(¹₀n)</h3>
From the question given above, we were told that:
<u>A fast-moving neutron strikes a ²³⁵U nucleus. The nucleus shatters producing ¹⁵⁵Sm, ⁷⁸Zn, and three neutrons.</u>
The nuclear equation can be written as follow:
Neutron => ¹₀n
Uranium => ²³⁵₉₂U
Samarium => ¹⁵⁵₆₂Sm
Zinc => ⁷⁸₃₀Zn
Uranium + neutron —> Samarium + Zinc + 3 moles of neutron
<h3>²³⁵₉₂U + ¹₀n —> ¹⁵⁵₆₂Sm + ⁷⁸₃₀Zn + 3(¹₀n)</h3>
The nuclear equation above is balanced.
