practice\ndirections: identify whether the following substances are held together by ionic or covalent bonds.\nsubstance ionic or covalent\n1. water, h₂o\n2. propane, c₃h₈\n3. magnesium oxide, mgo\n4. methane, ch₄\n5. magnesium chloride, mgcl₂\n6. potassium bromide, kbr\n7. calcium chloride, cacl\n8. carbon dioxide, co₂\n9. ammonia, nh₃\n10. glucose, c₆h₁₂o₆
Answer
Explanation:
Step1: Recall bond - type rules
Ionic bonds form between a metal and a non - metal, while covalent bonds form between non - metals.
Step2: Analyze Propane ($C_3H_8$)
Carbon and hydrogen are non - metals, so it has covalent bonds.
Step3: Analyze Magnesium oxide ($MgO$)
Magnesium is a metal and oxygen is a non - metal, so it has ionic bonds.
Step4: Analyze Methane ($CH_4$)
Carbon and hydrogen are non - metals, so it has covalent bonds.
Step5: Analyze Magnesium chloride ($MgCl_2$)
Magnesium is a metal and chlorine is a non - metal, so it has ionic bonds.
Step6: Analyze Potassium bromide ($KBr$)
Potassium is a metal and bromine is a non - metal, so it has ionic bonds.
Step7: Analyze Calcium chloride ($CaCl_2$)
Calcium is a metal and chlorine is a non - metal, so it has ionic bonds.
Step8: Analyze Carbon dioxide ($CO_2$)
Carbon and oxygen are non - metals, so it has covalent bonds.
Step9: Analyze Ammonia ($NH_3$)
Nitrogen and hydrogen are non - metals, so it has covalent bonds.
Step10: Analyze Glucose ($C_6H_{12}O_6$)
Carbon, hydrogen, and oxygen are non - metals, so it has covalent bonds.
