Answer:
The molar concentration of radon is 4.38 x 10⁻⁶ mol.L⁻¹
Explanation:
Molar fraction = number of moles of a certain component / total number of moles
Partial pressure = Total pressure x molar fraction
Partial pressure = 34 atm x 3.2 x 10⁻⁶
Partial pressure = 1.09 x 10⁻⁴ atm
Considering radon as an ideal gas, PV = nRT
molar concentration = n/V
n/V = P/RT
n/V = 1.09 x 10⁻⁴ atm / 0.082 L.atm.mol⁻¹K⁻¹ x 303.15K
n/V = 4.38 x 10⁻⁶ mol.L⁻¹
the most important methods are A and B
Ernest Rutherford was a famous British physicist who lived and worked in the 19th and the first half of the 20th century. He is now considered to be the father of nuclear physics, given that he was the one responsible for figuring out about the nuclear structure of an atom (proton, electron, neutron) and about the nuclear processes in general. The element rutherfordium (Rf) is named after this scientist. When it comes to his personal life, his parents are both British, however, Ernest was born in New Zealand because his mom and dad before he was born. He worked as a professor in several universities, and was even knighted in 1914. He is a Nobel prize winner, which he won for Chemistry in 1908.
Answer:
1
The heat of reaction is
The enthalpy is
2
The concentration of HCl is
Explanation:
From the question we are told that
The volume of is
The number of concentration of is
The volume of HCl is
The number of concentration of is
The temperature difference is
Now the heat of reaction is mathematically represented as
Where
is the specific heat of water with value
Now
where is the molar mass of NaOH with the value of 0.04 kg/mol
So
While
Where is the molar mass of with the value of 0.03646 kg/mol
So
=>
The enthalpy is mathematically represented as
=>
From the second question we are told that
The volume of HCl is
The volume of NaOH is
The concentration of NaOH is
The first temperature change is
The second volume of
The mass of NaOH is
substituting values
The mass of the product formed is
substituting values
The multiplication by 1000 is to convert it from kg to grams
Now the mass of HCl is
substituting values
Now the concentration of HCl is
The multiplication of is to convert it from kg/mol to g/mol
B. has the storms strongest winds is not a characteristic of the eye of a hurricane because in the eye it is actually completely calm.
Hope that helps u!!
