Are these correct ?! Please help !!!!!

Separate this redox reaction into its balanced component half-reactions. What is the oxidation and reduction half reactions

erma4kov [3.2K]

Separate this redox reaction into its component half-reactions.
Cl2 + 2Na ----> 2NaCl

reduction: Cl2 + 2 e- ----> 2Cl-1
oxidation: 2Na ----> 2Na+ & 2 e-

2) Write a balanced overall reaction from these unbalanced half-reactions:

oxidation: Sn ----> Sn^2+ & 2 e-
reduction: 2Ag^+ & 2e- ----> 2Ag

giving us
2Ag^+ & Sn ----> Sn^2+ & 2Ag Steve O · 5 years ago

Coffee is decaffeinated industrially using supercritical (sc) CO2. One advantage to using scCO2 is that the polarity of the supe

koban [17]

Answer:

Yes

Explanation:

A supercritical fluid has good properties for both liquid and as for extraction properties, the advantages then include:

The fact that it has a lower viscosity than liquid CO2 allowing it to move through and around coffee beans more thoroughly with creating back pressure
Its density is comparable to that of liquid CO2 meaning there is much CO2 per litre as there is liquid form making it more efficient
It has a higher diffusivity than liquid CO2 which aids with penetration of the coffee beans on a molecular level

This experiment would not work with tea leaves because they also contain caffeine

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

Serggg [28]

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 Rn per second 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

If you were able to magnify a penny down to the atomic level, what two

The two observations you would make about the atoms are

They are made up largely of empty space
Their mass is concentrated at the center called a nucleus

These observations were made by Ernest Rutherford in his model of the atom established in 1911, when he performed his gold foil experiment and observed the scattering angle of the alpha particles which led him to conclude that the mass of the atom was concentrated at the center.

Also, that most of the alpha particles also went through the gold foil suggested that the atom was made up basically of empty space.

So,
