    • Tidak ada jawaban benar

    Correct Answer
    A. NH4Cl, KOH, Na2CO3
    Explanation
    The correct answer is NH4Cl, KOH, Na2CO3. This is because ammonium chloride (NH4Cl) is an ionic compound composed of ammonium ions (NH4+) and chloride ions (Cl-). Potassium hydroxide (KOH) is also an ionic compound composed of potassium ions (K+) and hydroxide ions (OH-). Sodium carbonate (Na2CO3) is a compound composed of sodium ions (Na+) and carbonate ions (CO3^2-). Therefore, the given compounds have the correct chemical formulas.

    • 2

    • 1

    • 3

    • 4

    • 5

    Correct Answer
    A. 2
    Explanation
    The equation represents the reaction between hydrogen gas (H2) and iodine gas (I2) to form hydrogen iodide (HI). In order for the reaction to be balanced, there needs to be an equal number of hydrogen and iodine atoms on both sides of the equation. Since there is only one iodine atom on the left side, the coefficient for I2 should be 1. Therefore, the correct answer is 2, indicating that there are two hydrogen molecules reacting with one iodine molecule to produce two molecules of hydrogen iodide.

    • Magnesium Fluorida

    • Magnesium Fosfat

    • Magnesium Mono Fluorida

    • Magnesium Monosulfat

    • Magnesium Di Fosfatida

    Correct Answer
    A. Magnesium Fluorida
    Explanation
    The correct answer is Magnesium Fluorida. This is because the compound with the chemical formula MgF2 is made up of one magnesium (Mg) atom and two fluoride (F) atoms. When naming ionic compounds, the name of the cation (in this case, magnesium) is written first, followed by the name of the anion (in this case, fluoride) with its ending changed to "-ide". Therefore, the correct name for MgF2 is Magnesium Fluorida.

    Persamaan berikut :aMg   +   bHCl  ------> cMgCl2   +   dH2Supaya persamaan reaksi diatas setara nilai a,b,c,d berturut-turut adalah.....

    • 1,2,1,1

    • 2,2,2,1

    • 1,1,2,2

    • 3,1,2,1

    • 1,1,1,1

    Correct Answer
    A. 1,2,1,1
    Explanation
    The balanced equation for the reaction given is aMg + bHCl → cMgCl2 + dH2. To balance the equation, we need to ensure that the number of atoms of each element is equal on both sides of the equation. In this case, we have 1 atom of Mg on the left side and 1 atom of Mg on the right side, so a = 1. Similarly, we have 2 atoms of H on the left side and 2 atoms of H on the right side, so b = 2. For Cl, we have 1 atom on the left side and 2 atoms on the right side, so c = 1. Finally, we have 0 atoms of S on the left side and 1 atom of S on the right side, so d = 1. Therefore, the correct values for a, b, c, and d are 1, 2, 1, and 1 respectively.
