    What is the IUPAC name of NaOH? - ProProfs

    What is the IUPAC name of NaOH?

    • Sodium oxalocetic

    • Nitrate oxygen

    • Sodium bicarbonate

    • Sodium hydroxide

    Correct Answer
    A. Sodium hydroxide
    Explanation
    The IUPAC name of NaOH is Sodium hydroxide. This is because Na represents the element sodium, and OH represents the hydroxide ion. In IUPAC nomenclature, the name of a compound is derived from the elements present in it. Sodium hydroxide is a strong base commonly used in various industrial and laboratory applications.

    Which of the following correctly rep Avogadro's constant? - ProProfs

    Which of the following correctly rep Avogadro's constant?

    • 6.02×10^23

    • 6.35×10^ 34

    • 6.82×10^45

    • Non of the above

    Correct Answer
    A. 6.02×10^23
    Explanation
    Avogadro's constant is a fundamental constant in chemistry that represents the number of particles (atoms, molecules, ions) in one mole of a substance. The correct answer, 6.02×10^23, is the value of Avogadro's constant. This value indicates that there are approximately 6.02×10^23 particles in one mole of a substance. The other options, 6.35×10^34 and 6.82×10^45, are significantly larger and therefore do not correctly represent Avogadro's constant.

    Which of the following is true? - ProProfs

    Which of the following is true?

    • Acid +base= water

    • Acid +base=salt

    • Base +water= Acid

    • Acid +Base= salt+water

    Correct Answer
    A. Acid +Base= salt+water
    Explanation
    When an acid and a base react, they undergo a chemical reaction called neutralization. In this reaction, the acid donates a proton (H+) to the base, forming water (H2O) as a product. Additionally, the remaining ions from the acid and base combine to form a salt. Therefore, the statement "Acid + Base = salt + water" is true.

    What is an acid? - ProProfs

    What is an acid?

    • They are substances when dissolved in water produces hydrozonion ion

    • Hydroxide of metals

    • Oxide of halogens

    • Non of the above

    Correct Answer
    A. They are substances when dissolved in water produces hydrozonion ion
    Explanation
    An acid is a substance that, when dissolved in water, releases hydrogen ions (H+). These hydrogen ions combine with water molecules to form hydronium ions (H3O+), also known as hydroxonium ions. This is why the correct answer states that acids produce hydrozonion ions when dissolved in water.

    What is the IUPAC name of HNO3 - ProProfs

    What is the IUPAC name of HNO3

    • Nitrate acid

    • Nitric acid

    • Nitrogen acid

    • Non of the above

    Correct Answer
    A. Nitric acid
    Explanation
    The IUPAC name of HNO3 is Nitric acid. This is because the compound consists of a nitrogen atom bonded to three oxygen atoms and one hydrogen atom. The prefix "nitric" indicates the presence of nitrogen in the compound, while the suffix "acid" indicates that it is an acidic compound. Therefore, the correct IUPAC name for HNO3 is Nitric acid.

    What is base? - ProProfs

    What is base?

    • Oxide and hydroxide of  halogens

    • Oxide and peroxide of anions

    • Oxide and oxyalogen of anions

    • Oxide and hydroxide of metals

    Correct Answer
    A. Oxide and hydroxide of metals
    Explanation
    The correct answer is "Oxide and hydroxide of metals." This is because bases are substances that can accept protons or donate electron pairs, and they typically react with acids to form salts and water. Oxides of metals are basic in nature and can react with water to form hydroxides. Hydroxides of metals are also basic compounds. Therefore, the combination of oxides and hydroxides of metals represents the definition of a base.

    Which of the following is not an example of acid? - ProProfs

    Which of the following is not an example of acid?

    • H2so4

    • Hcl

    • HNO3

    • NH3

    Correct Answer
    A. NH3
    Explanation
    NH3 is not an example of an acid because it is a base. Acids are substances that release hydrogen ions (H+) when dissolved in water, while bases are substances that release hydroxide ions (OH-) when dissolved in water. NH3, also known as ammonia, does not release H+ ions but instead accepts them, making it a base.

    Which of the following is a salt? - ProProfs

    Which of the following is a salt?

    • NH3

    • NH4

    • Cu2SO4

    • H3O

    Correct Answer
    A. Cu2SO4
    Explanation
    Cu2SO4 is a salt because it is composed of a cation (Cu2+) and an anion (SO4 2-) held together by ionic bonds. Salts are compounds formed when the hydrogen ions of an acid are replaced by metal ions or other positive ions. In Cu2SO4, the Cu2+ ion is the cation and the SO4 2- ion is the anion.

    Which of the following is not an example of base?  - ProProfs

    Which of the following is not an example of base? 

    • Naoh

    • NH4

    • CuO

    • Cao

    Correct Answer
    A. NH4
    Explanation
    NH4 is not an example of a base because it is the chemical formula for ammonium, which is actually an example of an acid. A base is a substance that can accept or donate a pair of electrons, while an acid is a substance that can donate a proton. NH4 is an ammonium ion, which is formed when ammonia (NH3) accepts a proton (H+), making it an acid rather than a base.
