Answer:
Cells
Explanation:
High-powered microscopes are used in order to see microscopical (extremely small) structures of objects that cannot be seen with a naked eye.
When we look at a leaf, we will see the composition of it and the structural patterns that we couldn't see clearly or at all without a microscope.
Leaves consist of cells and spores (stomata) between the cells. Using a microscope will enable us to see them.

Answer:
S = 21.92 %
F = 78.08 %
Explanation:
To find the percent composition of each element in SF6, we must find the molar mass of SF6 first.
Molar mass of SF6 = 32 + 19(6)
= 32 + 114
= 146g/mol
mass of Sulphur (S) in SF6 = 32g
mass of Fluorine (F) in SF6 = 114g
Percent composition = mass of element/molar mass of compound × 100
- % composition of S = 32/146 × 100 = 21.92%.
- % composition of F = 114/146 × 100 = 78.08%.
