<span>Magnetic fields in certain materials (most commonly metals) are created due to moving electrons within these materials, which create an electric current.The distribution of electrons in these metals is uneven, resulting in an irregular rotation and lots of movement that then creates two magnetic poles (a north and south pole). When these poles align and face the same direction, they create a magnetic field.</span>

= 140.1 amu is the atomic mass of the element
One of the major characteristics in an addition polymerization is letter B. "<span>The polymer contains all the atoms in the monomer units." In addition to that, addition polymerization takes place due to an addition reaction, wherein bonds were rearranged together as monomers bond.</span>
Litmus paper is an indicator that changes color to identify the acidity or basicity of a certain substance. This changes color from blue to red for acids. Since given the same concentration of the compounds, the number of H⁺ in H₂SO₄ is approximately twice that of HCl.
Therefore, fewer drops of H₂SO₄ will be required in order to change the color of the litmus paper.
