Calcium is a chemical element with symbol Ca and atomic number 20. Calcium is a soft gray Group 2 alkaline earth metal, fifth-most-abundant element by mass in the Earth's crust. The ion Ca2+ is also the fifth-most-abundant dissolved ion in seawater by both molarity and mass, after sodium, chloride, magnesium, and sulfate.[5] Free calcium metal is too reactive to occur in nature. Calcium is produced in supernova nucleosynthesis.
Explanation:
I think that if you use different methods that result in the same outcome <em>you </em><em>will </em><em>have </em><em>more </em><em>chances </em><em>of </em><em>getting </em><em>the </em><em>required </em><em>res</em><em>u</em><em>l</em><em>t</em><em>.</em><em> </em><em>This </em><em>is </em><em>because </em><em>you </em><em>don't </em><em>know </em><em>whether </em><em>one</em><em> </em><em>of </em><em>your </em><em>methods</em><em> </em><em>might </em><em>work </em><em>or </em><em>not</em><em>, </em><em>so</em><em> </em><em>having </em><em>many </em><em>of </em><em>them </em><em>help </em><em>you. </em>
Not sure if I'm correct or not but I hope this helps
