Answer:- B: 4.21 is the correct option.
Solution:- The given balanced equation is:
From the balanced equation, there is 1:1 mol ratio between and Sn.
To calculate the moles of required to produce500.0 grams of Sn, we need to convert the grams to moles and multiply it by the mole ratio as:
=
So, the correct option is B: 4.21 moles.

Hope this helps!
Answer:
B. Na and Li
Explanation:
Only lithium and Sodium will have similar properties based on their groupings in the periodic table.
The periodic table of elements shows the arrangement of elements based on their atomic number.
- As general rule, elements in the same group on the periodic table will have the same chemical properties
- This is because they have the same number of valence electrons.
- Valency of an atom determines the chemical properties of such atom.
The empirical formula of the compound containing 0.64 g of copper, 0.32 g of sulphur and 0.64 g of oxygen is CuSO₄
From the question given above, the following data were obtained:
Mass of Cu = 0.64 g
Mass S = 0.32 g
Mass of O = 0.64 g
<h3>Empirical formula =? </h3>
The empirical formula of the compound can be obtained as follow:
Cu = 0.64 g
S= 0.32 g
O = 0.64 g
Divide by their molar mass
Cu = 0.64 / 63.5 = 0.01
S= 0.32 / 32 = 0.01
O = 0.64 / 16 = 0.04
Divide by the smallest
Cu = 0.01 / 0.01 = 1
S= 0.01 / 0.01 = 1
O = 0.04 / 0.01 = 4
Therefore, the empirical formula of the compound is CuSO₄
