    Study Notes

    Importance of Liquid Materials

    • Knowing the properties of common liquid materials is crucial in various applications.

    Ethyl Alcohol Uses

    • Ethyl alcohol is used as a solvent, antiseptic, and fuel.

    Methane Uses

    • Methane is commonly used as a fuel and in the production of electricity.

    Preservatives for Fish

    • To preserve a fish for a Biology class project, Maria Paula should use a compound like formalin or paraformaldehyde.

    Chocolate Mousse Recipe

    • To prepare a 250-g chocolate mousse containing 30% cream, 75g of cream would be needed (250g x 0.30 = 75g).

    Covalent Compounds

    • Water (H₂O) is an example of a covalent compound.

    Avogadro's Number

    • Avogadro's number represents the number of particles in 1 mole, which is 6.022 x 10²³ particles.

    Mole Concept in Environmentalism

    • Knowledge of the mole concept is useful for environmentalists in calculating the amount of substances in the environment and predicting the effects of pollution.

    Percentage Composition Applications

    • Knowledge of percentage composition is useful in calculating the amount of ingredients in a product, determining the purity of a substance, and comparing the composition of different substances.

    Atomic Combination

    • The valence electrons of an atom are important in determining how atoms combine.

    Ionic Bonding

    • Ionic bonding takes place through the transfer of electrons between atoms, resulting in the formation of ions with opposite charges that attract each other.

    Oxygen Bonding

    • A covalent bond is formed between two oxygen atoms (O₂).

    Electrolytes in Sports Drinks

    • Sucrose is not considered an electrolyte in sports drinks.

    Solubility of Sodium Chloride

    • The high solubility of sodium chloride (NaCl) in water is due to the strong attraction between the sodium and chloride ions and the polar water molecules.
