The three functional groups are carboxylic acids, amines and phenols. These functional groups can be turn to ions by adjusting their pH during extraction.
Their chemical strictures are as follows:
Carboxylic acid: RCOOH
Amines: RNH2
Phenols: C6H6O.
Transparent - when light is in context with transparent materials almost all of the the light is allowed to go through these materials.
Ex: glass
Translucent- materials that do not allow light to pass through easily.
Ex: tissue paper
Opaque- materials that allow no light to go through them .
Ex: wood
Answer:
The answer to your question is: 3.745 x 10 ²³ atoms
Explanation:
Data
density = 8.96 g/cm³
mass = 29.54 g
atomic radius = 1.28 A° 1.28 x 10⁻¹⁰ m
Volume of a cube
density = mass / volume
volume = mass / density
volume = 29.54 / 8.96
volume = 3.29 cm³
Volume of a copper atom
volume = (4/3) πr³
volume = (4/3) π (1.28 x 10 ⁻⁸)³
= 8.784 x 10 ⁻²⁴ cm³
Number of atoms = 3.29 cm³ / 8.784 x 10 ⁻²⁴ cm³
= 3.745 x 10 ²³ atoms
Answer:
Explanation: The molar mass of a substance is defined as the mass of 1 mol of that substance, expressed in grams per mole, and is equal to the mass of 6.022 × 10 23 atoms, molecules, or formula units of that substance
