Response: In transverse waves, the movement occurs perpendicular to the vibration source.
In contrast, longitudinal waves oscillate parallel to the source of vibration.
Both types share a common aspect: they facilitate energy transfer within the respective wave forms.

The soccer field's length is 3.94 × 10^2 in.
Length = 100 m × (39.37 in/1 m) = 394 in = 3.94 × 10^2 in
The empirical formula is K₂CO₃.
This formula represents the most simplified whole-number ratio of atoms in a chemical compound.
The atom ratio aligns with the mole ratio, which means our task is to find the molar ratios for K:C:O.
I prefer to summarize these calculations in table form.
Element Moles Ratio¹ Integers²
K 0.104 2.00 2
C 0.052 1.00 1
O 0.156 3.00 3
¹ To obtain the molar ratio, each mole value is divided by the smallest mole count.
² Convert the ratio values to integers (2, 1, and 3).
The empirical formula is K₂CO₃.
Answer:
Explanation:
The percent composition indicates the mass percentage of a specific element within the compound.
The chemical formula for chromium(III) nitrate is 
.
The molar mass for chromium(III) nitrate is calculated at 238.011 g/mol.
Each mole of chromium(III) nitrate includes 9 moles of oxygen.
The molar mass of oxygen is 16 g/mol.
Hence, Mass = Molar mass * Moles = 16 * 9 g = 144 g.
