A student observes the chemical process described by this equation:
choli [55]

Answer:

Both are equal

Explanation:

Mass of starting material i.e Aluminium is 4.480 * 10^{-23} grams

The weight of oxygen is 2.65 * 10^{-23}

There are 4 atoms of aluminium and 3 atoms of oxygen

Thus, the total mass of starting material is

4 * mass of one atom of aluminium + 6 * mass of one atom of oxygen

4 * 4.480 * 10^{-23} +  6* 2.65 * 10^{-23}

35.1 * 10^{-23} grams

Mass of new substance is also equal to

4 * mass of one atom of aluminium + 6 * mass of one atom of oxygen

4 * 4.480 * 10^{-23} +  6* 2.65 * 10^{-23}

35.1 * 10^{-23} grams

2LiClO+KHSO - Li2SO4 + Cl2 + KOOH
agasfer [191]

Answer:

2.5 moles of KOOH are produced.

Explanation:

1)Given data:

Number of moles of KOOH produced = ?

Number of moles of LiClO = 5 mol

Solution:

Chemical equation:

2LiClO +  KHSO₄     →      Li₂SO₄ + Cl₂ + KOOH

now we will compare the moles of KOOH and LiClO.

                 LiClO          :          KOOH

                    2              :              1

                   5               :             1/2×5 = 2.5

2.5 moles of KOOH are produced.
