Radon (Rn) is the heaviest, and only radioactive, member of Group 8A(18) (noble gases). It is a product of the disintegration of

heavier radioactive nuclei found in minute concentrations in many common rocks used for building and construction. In recent years, there has been growing concern about the cancers caused from inhaled residential radon. If 1.0X10¹⁵atoms of radium (Ra) produce an average of 1.37X310⁴ atoms of Rn per second, how many liters of Rn, measured at STP, are produced per day by 1.0 g of Ra?

Given data                Atomic mass of Ra= 226g/mol

no. of moles =1.0/226g/mol           =0.04424moles

no. of atoms in 0.044moles

no. of atoms =no. of moles x avogadro's number

= 0.044x 6.022 x10^23                  = 0.264968 x 10^22

 If 10^15  atoms of Ra produce 1,373*10^4  atoms of<u> Rn per second</u> then 2,66 *10^21  forms 3,658*10^10 atoms of Rn per second.

Day has 246060=86400 s

That means that 2,66x10^21  atoms of Ra produces 3,16 x10^15  atoms of Rn in a day.

N(Rn)=3.16* 10 ^15                           n(Rn)=N/NA

n(Rn)=5,25*10−9                              pV=nR*T

T=273.15K                                        R=8,314

p=101325Pa                                      V=n∗R∗T/p

V=5.25∗10^−9 ∗ 8.314 ∗ 273.15  /  101325

V=1.1810^−10 m^3 =   118 x10^-7 liters of Rn, measured at STP, are produced per day by 1.0 g of Ra

What is a reaction mechanism
ehidna [41]

Answer:

In chemistry, a reaction mechanism is the step by step sequence of elementary reactions by which overall chemical change occurs. A chemical mechanism is a theoretical conjecture that tries to describe in detail what takes place at each stage of an overall chemical reaction.

What is the purpose of a salt bridge?
k0ka [10]

Answer:

A salt bridge refers to a device used to form an electrochemical cell by providing a means to support the free flow of ions between the oxidation and reduction half-cell components. A salt bridge facilitates corrosion because corrosive reactions typically occur in the presence of electrochemical cells.

Calculate the number of moles in 9 g of water​
tangare [24]

Answer:

= 0.5 moles of water

formular \: mass \: of \: water \:  = (2 \times 1)  + 16  = 18 \\ 18g \: of \: water \: are \: weighed \: by \: 1 \: mole. \\ 9g \: will \: be \: weighed \: by \:  \frac{9 \times 1}{18}  \\  =  \frac{9}{18} moles \\  = 0.5 \: moles \: of \: water
