What is the equation for when an iron -53 goes through alpha decay and beta decay

Chemistry
1 answer:
Semenov [28]3 years ago
3 0

Answer:

Explanation:

β decay is a process in which a nucleus emits an electron.

The nuclear symbol for a β particle is

l

0

-1

e

.

In any nuclear equation, the sum of the subscripts (atomic numbers,

Z

) and the sum of the superscripts (atomic masses,

M

) must be equal on each side of the equation.

For the β decay of iodine 131, we have

131

53

I

→

l

M

Z

X

+

l

0

-1

e

Hence

131

=

M

+

0

, so

M

=

131

53

=

Z - 1

, so

Z

=

53

+

1

=

54

The element

X

with

Z = 54

is

Xe

.

So the equation is

131

53

I

→

131

54

Xe

+

l

0

-1

e

Note that in β decay, the product has the same mass number but an atomic number that has increased by 1.

Construct an argument for or against the immediate introduction of fuel-cell cars. Include likely points of objection from those
ryzh [129]

Answer:

Explanation:

Fuel Cell Cars are the vehicles built to run on hydrogen gas rather than running on the hydrocarbon.

Hydrocarbons are the organic compounds which are derived mostly from the crude oil. They are usually composed of Hydrogen and Carbon.

Fuel cell cars are much more better than the regular vehicles running on hydrocarbon in so many ways especially environmentally.

Listed below are some of the advantages of fuel cell cars over the regular vehicles

Fuel cells have a higher efficiency than diesel or gas engines.

Most fuel cells operate silently, compared to internal combustion engines. They are therefore ideally suited for use within buildings such as hospitals.

Fuel cells can eliminate pollution caused by burning fossil fuels; for hydrogen fuelled fuel cells, the only by-product at point of use is water.

If the hydrogen comes from the electrolysis of water driven by renewable energy, then using fuel cells eliminates greenhouse gases over the whole cycle.

Fuel cells do not need conventional fuels such as oil or gas and can therefore reduce economic dependence on oil producing countries, creating greater energy security for the user nation.

Since hydrogen can be produced anywhere where there is water and a source of power, generation of fuel can be distributed and does not have to be grid-dependent.

The use of stationary fuel cells to generate power at the point of use allows for a decentralised power grid that is potentially more stable.

Why is it that the north star is the only star in the night sky that seems to stay still
Masja [62]

I think it is because it is directly about the north or south pole (I forget) so while all the other stars seem to rotate around because the Earth is rotating but the North Star is directly in the center. Don't take my word though.

Which of the following solutions would have the highest osmotic pressure?
Gennadij [26K]

Answer:

Option d. 0.10 m Cr₂(SO₄)₃

Explanation:

Formula for the osmotic pressure is determined as:

π = M . R . T . i

So you have to take account the i (Van't Hoff factor, numbers of ions dissolved)

  • CH₄N₂O → 0.35 m

Urea is an organic compound, so the i value is 1

  • H₂O → The i is also 1
  • Zn(CH₃COO)₂ → 0.15 m

Zync acetate can be dissociated:

Zn(CH₃COO)₂  →  1Zn²⁺  + 2CH₃COO⁻

In this case, the i is 3. (you see, the stoichiometry of ions)

Cr₂(SO₄)₃ →  0.10 m

Chromium sulfate is dissociated:

Cr₂(SO₄)₃ →  2Cr³⁺  +  3SO₄⁻²

i = 5

BaI₂ → 0.16 m

BaI₂ →  1Ba²⁺  +  2I⁻

i = 3

What is included in counting the electron domain around the central atom vsepr theory
In-s [12.5K]

Answer:

Lone pairs and bonding pairs  

Explanation:

The electron domain around the central atom includes

  • All lone pairs on the central atom
  • All bonding pairs between the central atom and the atoms directly attached to it

Double and triple bonds count as single domains.

Thus, the nitrite ion has three electron domains:

  1. A lone pair
  2. An N-O single bond
  3. An N-O double bond
