Answer

Brief Explanations:

  1. Gold Leaf: Gold is used for its malleability, resistance to corrosion etc. The "Bible of gold leaf" is unclear without more context. Pure gold is refined through methods like electrolytic refining.
  2. Sand: Black grains in sand can be minerals like magnetite. A sand - particle is much larger than an atom.
  3. Julia Childes: The white layer of burnt food could be ash (inorganic salts). Burnt food is black due to carbonization. Food mostly contains carbon atoms. A chemical element is a pure substance made of only one type of atom.
  4. Electrolysis of Water: The proportion of oxygen to hydrogen in water is 1:2 by number of atoms. Electrolysis is the decomposition of a substance by an electric current, and in water, it splits water into hydrogen and oxygen gases.

Answer:

  1. Reasons for using gold: Malleability, corrosion - resistance. Stat of "Bible of gold leaf" is unclear. Pure gold refining method: Electrolytic refining.
  2. Black grains in sand: Minerals like magnetite. Sand - particle vs atom size: Sand - particle is much larger.
  3. White layer of burnt food: Ash (inorganic salts). What makes burnt food black: Carbonization. Atom in food: Carbon. Chemical element: Pure substance of one - type atom.
  4. Proportion of oxygen to hydrogen in water: 1:2. Electrolysis: Decomposition by electric current, e.g., splitting water into H₂ and O₂.
