Of the following given choices;
A. iron
B. plastic
C. aluminum
D. wood
The answer is; A
Magnetism is the result from the unpaired spins of electrons in the orbital shells of the atoms of an element. Aluminum (though a metal with +3 valency like iron) has it S and P orbitals filled hence most of its electrons are paired. Iron, on the other hand, a transitional metal, has a D orbital that can be filled before the P orbital is filled. Therefore, there is a higher net unpaired spin of electrons giving the atoms net magnetic properties.
You have to solve it and color in the numbers i guess? It doesnt show all of the work
Nylon is named as the most useful synthetic material. Nylon belongs to a family of materials called "polyamides."
Moles of Sulfuric acid- H₂SO₄ needed to react completely : 3.2 moles
<h3>Further explanation</h3>
A reaction coefficient is a number in the chemical formula of a substance involved in the reaction equation. The reaction coefficient is useful for equalizing reagents and products.
Reaction(balanced)
<em>2LiOH + H₂SO₄ → Li₂SO₄ + 2H₂O</em>
From the reaction equation above, the reaction coefficient shows the mole ratio of reagents and products
moles of Lithium hydroxide-LiOH = 6.4 moles
mol ratio of LiOH : H₂SO₄ = 2 : 1, so mol H₂SO₄ :
