Question: Use The Periodic Table of the Elements and the information below to answer the question. Magnesium metal (Mg) is grayish-white in color and reacts actively with water. Fluorine (F2) is a greenish-yellow gas at room temperature and is a member of the halogen family. These two elements react to produce magnesium fluoride (MgF2), a chemical commonly used in making windows and lenses. How do the elements magnesium (Mg) and fluorine (F2) produce the compound magnesium fluoride (MgF2)?
Answer: by chemically combining
Hypothesis: a chemical reaction is caused by magnesium and fluorine combined chemically
Supporting facts: sent1: the bonds of chemical compounds contain chemical energy sent2: amount is a property of something and includes ordered values of none / least / little / some / half / much / many / most / all sent3: chemical reactions cause new substances to form sent4: magnesium and fluorine react chemically producing magnesium fluoride sent5: fluorine is a kind of gas sent6: chemical bonds are formed by chemically combining elements / atoms / molecules sent7: combining two substances chemically causes chemical reactions sent8: a source of something increases the amount of that something sent9: magnesium oxide is a kind of compound sent10: in a chemical reaction reactants have the role of molecules / substances that chemically combine sent11: when two substances together form a compound then those substances cannot be physically separated sent12: magnesium is a kind of alkaline earth metal sent13: alkaline earth metal elements have two valence electrons sent14: to add means to combine sent15: chemical compounds contain chemical bonds between atoms / between elements sent16: chemical reaction means chemical bonds change sent17: sodium chloride is always made of chemically combined chlorine and sodium sent18: the chemical symbol for fluorine is f sent19: the periodic table is a table displays elements sent20: if the elements have similar electron configurations , then the elements will be grouped into same family / group on the periodic table of elements sent21: chemical reactivity is a property of elements and includes ordered values of reactive / unreactive sent22: a molecule of water is made of 2 hydrogen atoms and 1 oxygen atom sent23: calcium / beryllium / strontium / radium / barium / magnesium belongs to alkaline earth metal family , group 2 on the periodic table sent24: if a material / a substance is a mixture of two or more materials or substances then that material / substance is made / is formed / contains those materials / substances sent25: a molecule is made of atoms chemically combined / bonded
Reasoning: [BECAUSE] magnesium is a kind of alkaline earth metal [AND] magnesium and fluorine react chemically producing magnesium fluoride [AND] fluorine is a kind of gas [INFER] int1: magnesium fluoride is a new substance produced by magnesium and fluorine reacting chemically [BECAUSE] int1 [AND] chemical reactions cause new substances to form [INFER] int2: a chemical reaction happened between magnesium and fluorine [BECAUSE] int2 [AND] combining two substances chemically causes chemical reactions [INFER] int3: a chemical reaction is caused by magnesium and fluorine combined chemically
