There are five critical functions of skin. They are: Prevents loss of essential body fluids (blood), protects body from harmful effects of radiation and sun, allows for toxic substances to excrete (Sweat), supports the body by giving mechanical support, and regulates body temperature.
Answer:
One AMU or 1 Atomic Mass Unit
The most widely accepted explanation of how the solar system formed is called the nebular hypothesis. According to this hypothesis, the Sun and the planets of our solar system formed about 4.6 billion years ago from the collapse of a giant cloud of gas and dust, called a nebula

Answer:
0.86 g
Explanation:
Given:
Pressure = 725 torr
The conversion of P(torr) to P(atm) is shown below:
So,
Pressure = 725 / 760 atm = 0.9539 atm
Volume = 225 mL = 0.225 L (1 mL = 0.001 L)
Temperature = 25 °C
The conversion of T( °C) to T(K) is shown below:
T(K) = T( °C) + 273.15
So,
T₁ = (25 + 273.15) K = 298.15 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
0.9539 atm × 0.255 L = n × 0.0821 L.atm/K.mol × 298.15 K
⇒n = 0.0099 moles
From the reaction,
1 mole of chlorine is formed from 1 mole of
Thus, moles of = 0.0099 moles
Molar mass of = 86.9368 g/mol
Mass = Moles*Molar mass = 0.0099 moles * 86.9368 g/mol = 0.86 g
