Neurilemma (also known as neurolemma, sheath of Schwann, or Schwann's sheath) is the outermost nucleated cytoplasmic layer of Schwann cells (also called neurilemmocytes) that surrounds the axon of the neuron. ... In the central nervous system, axons are myelinated by oligodendrocytes, thus lack neurilemma.
water is a major dissolved volatile constituent in both magmas and volcanic gases
Answer:
The answer is
<h3>1.340 × 10²⁴ sodium atoms</h3>
To find the number of atoms of sodium we use the formula
N = n × L
where
n is the number of moles
N is the number of entities
L is Avogadro's constant which is
We need to find the number of moles first
The formula is
where
M is the molar mass
m is the mass
n is the number of moles
From the question
M = 22.9 g/mol
m = 51.0 g
n = 2.227 moles
So the number of sodium atoms is
We have the final answer as
<h3>1.340 × 10²⁴ sodium atoms</h3>

Answer:
First, let's express pressure P in Pa and volume V in m3:
⇒P=175 kPa
⇒P=1.75×105 Pa
and
⇒V=275 ml
⇒V=2.75×10−4 m3
Then, let's solve the ideal gas law PV=nRT for temperature T:
⇒PV=nRT
⇒T=PVnR
Substituting the appropriate values into the equation:
⇒T=1.75×105×2.75×10−40.80×8.314 K
⇒T=48.1256.6512 K
∴T≈7.24 K
Therefore, the temperature is around 7.24 K.
Answer:
True
Explanation:
Because electrons go in different paths they can be a wavy type of path and they have particle like properties too because they are small and then they can be in string like forms too.
