Chemical bonds are broken to supply us with energy. Without bonds, and our ability to break them, the food we eat would not supply us with energy.
Answer:
C9H13N
Explanation:
Since there is no common factor besides 1, the formula is already the empirical formula for this compound.
Answer:
For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively. Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively. Valence electrons are responsible for the reactivity of an element. They determine how "willing" the elements are to bond with each other to form new compounds.
Explanation: it might be 18 my guess:)
Word equation
Magnesium + Oxygen = Magnesium oxide
Symbolic equation
Mg + O2 = MgO
Balanced symbolic equation
2Mg + O2 = 2MgO
16.00 grams of oxygen
since in one mole the mass would be the molecular mass, which is found on the periodic table
