metals/non-metals 🪵

• What are the learning objectives of section 6.2.2?

  To name, classify, and describe oxidation reactions of metals and non-metals with oxygen.
• Why are metals suitable for making trumpets?

  Because metals are malleable and shiny.
• Why can't a trumpet be made from a non-metal like carbon?

  Because non-metals are brittle and cannot be shaped easily.
• What are three physical properties of a typical metal?

  • Malleable
  • Shiny
  • Good conductor of heat and electricity
• What are chemical properties used for in classifying elements?

  Chemical properties describe how elements react in chemical reactions.
• What new substances are formed when metals and non-metals react with oxygen?

  Oxides
• Write the word equation for the reaction of zinc with oxygen.

  zinc + oxygen → zinc oxide
• Write the word equation for the reaction of sulfur with oxygen.

  sulfur + oxygen → sulfur dioxide
• What are reactants in a chemical reaction?

  Reactants are the starting substances in a chemical reaction.
• What is the product of the reaction of zinc with oxygen?

  Zinc oxide
• What is an oxidation reaction?

  An oxidation reaction is when a substance reacts with oxygen to form one or more oxides.
• What happens when magnesium burns in oxygen?

  It reacts vigorously to form magnesium oxide.
• How does zinc react with oxygen?

  Zinc reacts with oxygen to form zinc oxide with bright white sparks.
• What is the product when iron reacts with oxygen?

  Iron oxide
• What is the reactivity of gold with oxygen?

  Gold is unreactive and does not burn in oxygen.
• What is formed when metals react with acids?

  Salts and hydrogen gas are formed.
• Write the word equation for the reaction of zinc with hydrochloric acid.

  zinc + hydrochloric acid → zinc chloride + hydrogen
• What happens when magnesium reacts with hydrochloric acid?

  It produces magnesium chloride and hydrogen gas.
• What is the product of the reaction of magnesium with sulfuric acid?

  Magnesium sulfate
• Which metals do not react with dilute acids?

  Platinum, gold, silver, and copper do not react with dilute acids.
• How do the reactions of different metals with dilute hydrochloric acid compare?

  Magnesium reacts most vigorously, while gold does not react at all.
• What is the product of the reaction of magnesium with nitric acid?

  Magnesium nitrate
• What is the general outcome when a metal reacts with an acid?

  A salt and hydrogen gas are produced.
• What is the product of the reaction of zinc with nitric acid?

  Zinc nitrate
• What is the significance of the word equation in chemical reactions?

  It represents the reactants and products in a chemical reaction.
• How do oxidation reactions differ from other types of chemical reactions?

  Oxidation reactions specifically involve a substance reacting with oxygen.
• What is the product of the reaction of copper with oxygen?

  Copper oxide
• What happens to magnesium when it is left in the air?

  Its surface atoms react with oxygen to form magnesium oxide.
• What is the pattern observed in the reactions of metals with oxygen?

  Metals generally react vigorously with oxygen to form oxides.
• What is the product of the reaction of iron with oxygen?

  Iron oxide
• What is the significance of the term 'oxide' in chemistry?

  An oxide is a compound formed when a substance reacts with oxygen.
• What is the product of the reaction of lead with hydrochloric acid?

  Lead chloride
• What is the role of hydrogen gas in metal-acid reactions?

  Hydrogen gas is a product formed during the reaction.
• How do the reactions of metals with acids compare to their reactions with oxygen?

  Both reactions produce different types of compounds, but acids produce salts while oxygen produces oxides.
• What is the product of the reaction of magnesium with hydrochloric acid?

  Magnesium chloride and hydrogen gas
• What is the outcome of the reaction of metals with sulfuric acid?

  It produces a sulfate salt and hydrogen gas.
• What is the product of the reaction of zinc with sulfuric acid?

  Zinc sulfate and hydrogen gas
• What is the significance of the term 'salt' in chemistry?

  A salt is formed when an acid reacts with a metal or metal-containing substance.
• How do the properties of metals compare to those of non-metals?

  Metals are malleable and shiny, while non-metals are brittle and dull.
• What is the product of the reaction of iron with sulfuric acid?

  Iron sulfate and hydrogen gas
