The pauli exclusion principle states that many electrons may have the same four quantum numbers. answer true false

1 answer:

3 0

The statement is false. We know this beause this principle states that impossible for two electrons to have the same four electronic quantums. Remember that the orbtials can each have only two electrons max.

Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of _______.

murzikaleks [220]

Cerebrospinal fluid of the central nervous system and synovial fluid of joint capsules are both examples of extracellular fluid

Extracellular fluid called cerebrospinal fluid is present throughout the CNS
It acts as a protective layer for CNS ftom injury and shock
Cerebrospinal fluid is clear, colorless fluid produced by the choroid plexus.
It surrounds the brain and spinal cord.

Synovial fluid is a viscous solution found in cavities of synovial joints. The principal role of synovial fluid is to reduce friction between articular cartilages of synovial joints during movement.

Synovial fluid is a small component of transcellular fluid component of extracellular fluid.

An aqueous solution of potassium sulfate (K2SO4) has a freezing point of -2.24

iragen [17]

An aqueous solution of potassium sulfate exhibits colligative properties. Colligative properties are properties that depends on the concentration of a substance in a solution. These properties are freezing point depression, vapor pressure lowering, osmotic pressure and boiling point elevation. For this problem we use the concept of freezing point depression since we are given the freezing point of the solution. Freezing point depression is as:

ΔT = -k(f) x m x i
-2.24 - 0 = -1.86 x m x 3
m = 0.4014

Thus, the molality of the solution is 0.4014.

The temperature is -14°C the air pressure in an automobile tire is 149K PA if the volume does not change what is the pressure af

Jet001 [13]

Answer: The pressure after the tire is heated to 17.3°C is 167 kPa

Explanation:

To calculate the final temperature of the system, we use the equation given by Gay-Lussac Law. This law states that pressure of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

$\frac{P_1}{T_1}=\frac{P_2}{T_2}$

where,

$P_1\text{ and }T_1$ are the initial pressure and temperature of the gas.

$P_2\text{ and }T_2$ are the final pressure and temperature of the gas.

We are given:

$P_1=149kPa\\T_1=-14^0C=(273-14)=259K\\P_2=?=27.5psi\\T_2=17.3^0C=(273+17.3)=290.3K$

Putting values in above equation, we get:

$\frac{149}{259}=\frac{P_2}{290.3}\\\\P_2=167kPa$

Hence, the pressure after the tire is heated to 17.3°C is 167 kPa

Which of dalton's postulates about atoms are inconsistent with later observations? do these inconsistencies mean that dalton was

Neporo4naja [7]

1) Dalton stated that atom is matter that can not be divided, but it is proved that the atom can be divided into subatomic particles (electrons, protons and neutrons).

2) He stated that atoms of one element can not be changed into atoms of other elements, but now that is possible by nuclear reactions.

Today we still use his postulate: Atoms combine in the ratio of small whole numbers to form stable compounds, for example H₂O.
