Answer:
B. False
Explanation:
Solution -
A solution is referred to be a uniform mixture of various components , where the components are classified as solute and solvent .
The components can easily be segregated on the basics of the amount of the component , i.e. ,
- The component with higher concentration is referred to as the solvent.
And ,
- The component with lower concentration is referred to as the solute .
For example ,
In the solution of sugar and water , where 1 tablespoon of sugar is dissolved in 100 mL of water ,
- the concentration of sugar is less , and hence , is referred to as the solute ,
and ,
- the concentration of water is more , and hence, is referred to as the solvent.
Photoelectron spectroscopy (pes) is a technique used for determining the ionization
potentials of molecules. Underneath the banner of PES are two separate techniques for
quantitative and qualitative measurements. They are ultraviolet photoeclectron
spectroscopy (UPS) and X-ray photoelectron spectroscopy (XPS). UPS focuses on
ionization of valence electrons while XPS is able to go a step further and ionize core
electrons and pry them away.
Answer:
Non-Metals can be all three.
Answer:
Option B. 10
Explanation:
If 1 mol of butanol contains 6×10²⁴ atoms of H, let's calculate the amount of H.
(number of atoms / NA)
6.02 x 10²³ atoms ___ 1 mol
6×10²⁴ atoms will occupy (6×10²⁴ / NA) = 9.96 moles
H, has 10 moles in the butano formula.
