Answer:
The root mean squared velocity for CF2Cl2 is
Explanation:
From the question we are told that
The temperature is
Root Mean Square velocity is mathematically represented as
Where T is the temperature
MW is the molecular weight of gas
R is the gas constant with a value of
For CF2Cl2 its molecular weight is 0.121 kg/mol
Substituting values
The oil slick thick = 1.256 x 10⁻⁴ cm
<h3>Further explanation</h3>Volume is a derivative quantity derived from the length of the principal
The unit of volume can be expressed in liters or milliliters or cubic meters
The conversion is
1 cc = 1 cm3
1 dm = 1 Liter
1 L = 1.06 quart
<em>so for 1 quart = 0.943 L</em>
Volume of oil dumped = volume of swimming pool
Answer:
12.78 kJ
Explanation:
The correct balanced reaction would be
Mass of methanol =
Moles of methanol can be obtained by dividing the mass of methanol with its molar mass
Enthalpy change for the number of moles is given by
The change in enthalpy is 12.78 kJ.
