    Fog near Los Angeles has been measured to be as acidic as vinegar.

    • True

    • False

    • I don't know

    Correct Answer
    A. True
    Explanation
    The given statement is true. Fog near Los Angeles has been measured to be as acidic as vinegar. This means that the pH level of the fog is very low, similar to the acidity level of vinegar. The high levels of air pollution in the Los Angeles area contribute to the acidity of the fog, which can have negative effects on the environment and human health.

    Starting in 1887, what was used by miners to extract gold from ore in a process called leaching? - ProProfs

    Starting in 1887, what was used by miners to extract gold from ore in a process called leaching?

    • Leaches

    • Cyanide

    • Milk

    • Chlorine bleach

    Correct Answer
    A. Cyanide
    Explanation
    In the late 19th century, miners began using cyanide to extract gold from ore in a process known as leaching. Cyanide is a highly effective chemical compound that dissolves gold and allows it to be separated from the surrounding rock and other impurities. This method revolutionized the mining industry as it provided a more efficient and cost-effective way to extract gold from large quantities of ore. The use of cyanide in gold extraction continues to be a common practice in modern mining operations.

    Filtering tap water through activated carbon removes _______ ? - ProProfs

    Filtering tap water through activated carbon removes _______ ?

    • Dissolved calcium

    • Nitrates

    • Bad tastes, odours, and color

    • Viruses

    Correct Answer
    A. Bad tastes, odours, and color
    Explanation
    Filtering tap water through activated carbon removes bad tastes, odors, and color. Activated carbon has a porous structure that helps to trap and absorb impurities in the water. It is particularly effective in removing organic compounds that can cause unpleasant tastes, odors, and discoloration. However, it does not remove dissolved calcium, nitrates, or viruses, as these substances require different filtration methods or treatments.
