1. Define fission and fusion. Give an example of fission and fusion reflecting in real life application.
Alja [10]

Answer :

  • Nuclear fission : In nuclear reaction, the nucleus of a larger atom breaks into two or more smaller nuclei. In fission process, protons and neutrons are produced and larger amount of energy is released.

Example : In nuclear power plant, the energy released from the process of nuclear fission which is converted into electrical energy that is used in our homes and factories.

  • Nuclear fusion : In nuclear reaction, the nuclei of two or more smaller atoms combine together to form single larger molecule. In fusion process, the mass of the resulting nuclei is more as compared to the starting nuclei and large amount of energy is also released.

Example : This process occurs in the sun and stars. In this, the isotopes of Hydrogen, Tritium and Deuterium combine together to form a neutron and a helium atom under high pressure and temperature.

In Chile, the deepest earthquake occurred at 61.7°W longitude at a depth of 540 km. If the rocks at the focus began subducting 1
victus00 [196]

The correct answer is - 1 cm/yr.

Alongside the western coast of South America, the Nazca plate and the South American plate are in a collision for several million years now, with the Nazca plate being the one that is subducting in this convergent plate boundary.

If the Nazca plate's focus has moved 1,000 km in the last 10 million years, than in order to get to the annual movement of the subduction we need to convert the km into cm first:

1 km = 10,000 cm

1,000 x 10,000 = 10,000,000

1,000 km = 10,000,000 cm

Than we need to divide the number of cm with the number of years:

10,000,000 / 10,000,000 = 1

And we get the result of 1 cm/yr.

What is the percent by mass of carbon in C10 H14 N2?
MrMuchimi
Multiply the number of each element by its mass on the periodic table.

Add them together.

Put the mass of carbon only over the total mass and multiply the result by 100 to get the percentage.
