Question

State one advantage of building a space station in orbit instead of sending it all up in one piece.

Solution 1

Building a space station in orbit is a safety measure. If a rocket fails to bring up the entire space station in one piece it would be extremely expensive to build a new one. Bringing it up in multiple places ensures less money would be lost if the rocket fails.

Question

Extreme (1, 2, or 3) in the center of nebulae causes hydrogen atoms to shed their electrons and collide with one another. The (4, 5, or 6) of the collisions cause the smaller, bare nuclei to fuse into large helium nuclei. 1. expansion 2. heat 3. density 4. size and luminosity 5. force and speed 6. mass and temperature

Solution 1

Extreme (Heat) in the center of nebulae causes hydrogen atoms to shed their electrons and collide with one another. The (force and speed) of the collisions cause the smaller, bare nuclei to fuse into large helium nuclei.

Solution 2

Answer:

2. heat

5. force and speed

Explanation:

Nuclear fusion in stars causes the hydrogen atoms to collide with each other and form the heavier helium atom. The fusion reaction is therefore:

₁H² + ₁H² → ₂He⁴

Extreme heat in the center of nebulae causes hydrogen atoms to shed their electrons and collide with one another. The force and speed of the collisions cause the smaller, bare nuclei to fuse into large helium nuclei.

Question

Why is radioactive decay a good method of measuring the absolute age of ancient fossils

Solution 1

radioactive decay is a good method of measuring the absolute age of ancient fossils because radioactive decay could be measure and confront again time in the most trusted and verifiable way, as it allows to have a degree of certainty that other measurements have not yet reached. it is also easy to test and compare with other methods.

Solution 2

Answer:

All ancient fossils contain C-14

Explanation:

All living things contain more than one isotope of carbon, the most prominent being, carbon -12 and carbon-14.

Carbon-14 is a radioactive isotope of carbon. When the artifact is retrieved, the activity of carbon-14 in that sample is matched with the carbon-14 activity of a living organism. When this is done, the age of the fossil can easily be accurately calculated.

Question

Balance the nuclear reaction equation for the beta minus decay of iodine-131 by completing the missing numbers. es001-1.jpg The superscript of xenon is . The subscript of the electron is .

Solution 1

Balanced nuclear reaction equation for the beta minus decay of iodine-131 is ${}_{{\rm{53}}}^{{\rm{131}}}{\rm{I}} \to {}_{54}^{{\rm{131}}}{\rm{Xe + }}{}_{{\rm{ - 1}}}^0{\rm{e}}$ .

What is nuclear reaction?

Nuclear reaction is a reaction which changes the identity of an atomic nuclei, when high energetic particles is bombarded on that.

Beta minus decay is one of the example of nuclear reaction, and in this reaction a neutron decays into an electron which is also known as beta particle having no mass in it. And at the same time gamma rays also. In the question, it is given that iodine-131 shows beta minus decay, where the superscript of xenon is 131 and subscript of electron is -1. i.e.

${}_{{\rm{53}}}^{{\rm{131}}}{\rm{I}} \to {}_{\rm{x}}^{{\rm{131}}}{\rm{Xe + }}{}_{{\rm{ - 1}}}^{\rm{y}}{\rm{e}}$

We have to balance the above equation and for that sum of the superscripts and subscripts is always equal on both left and right sides.

Calculation for superscripts:

131 = 131 + y

y = 0.

Calculation for subscripts:

53 = x - 1

x = 53 + 1 = 54

Hence, balanced nuclear equation can be written as ${}_{{\rm{53}}}^{{\rm{131}}}{\rm{I}} \to {}_{54}^{{\rm{131}}}{\rm{Xe + }}{}_{{\rm{ - 1}}}^0{\rm{e}}$ .

Solution 2

Answer:

131            131            0
      I    →         Xe   +     e
53             54           - 1

Explanation:

1) β decay is the radiactive process in which an element (Iodine - 131) in this case undergoes a desintegration by emitting beta radiation.

2) Beta radiation are electrons.

3) The electron has a negative charge 1-, and no mass (almost not mass), so it is represented with a left supersript 0 (does not change the mass number) and a left underscript 1- (the atomic number increases in 1).

4) Then when iodine-131 emits a beta particle (electron) its mass number does not change, but the atomic number is increased from 53 to 54, becoming the isotope xenon - 131.

That is what the superscript to the left of Xe shows (131), while the subscript shows 54.

The subscript of electron is - 1.

So the balance is:

Iodine              Xenon           electron

131       =          131       +       0

   53 =            54       -         1
