Describe some of the practical uses of controlled fission reactions.

Answers

Answer 1
Answer:

Some practical uses of controlled fission reactions are to produce electricity from the turbine source and as a power source in water craft.

What is fission reaction?

Fission process is one of the kind of nuclear reaction in which one large nuclei will convert into 2 or many small nuclei by the releasing of gamma photon radiation and lots of energy in the form of light and heat.

  • Heat generated in the fission reaction will be used to generate electricity through the turbine process by providing steam.
  • And another main use of controlled nuclear fission is used as power in many watercrafts like ships, submarines, etc.

Hence main uses of controlled fission reaction is to produce electricity and as a power.

Answer: Synthesis reaction

Explanation:

Corrosion is the process of slow eating away of metal due to attack of atmospheric gases on the surface of metal resulting into formation of compounds such as oxides, sulfides , carbonates etc is called as corrosion.

Corrosion of iron is called as rusting. Rust is hydrated ferric oxide (Fe_2O_3.xH_2O.

Which gas is not known as green house gas

Answers

Carbon dioxide is a main greenhouse gas, found in car exhaust pipes. Methane and nitrous oxide is another type of greenhouse gas. Oxygen is the only clean gas out there because we need it to survive. Therefore, the only gas that is not a greenhouse gas is (c) oxygen.

A man relaxes in his hot tub after a day at work. his body temp is 98.6F and the water is 102Fhow does the heat transfer?
A. Heat does not transfer between his body and the water
B. Heat transfers to his body from the water by conduction
C. Heat transfers from his body to the water by convection
D. Heat transfers from his body to the water by conduction
Thank you !

Answers

Answer is: B. Heat transfers to his body from the water by conduction.

Thermal conductuction is the transfer of heat through physical contact. Thermal conduction is the transfer of heat by microscopic collisions of particles.

Heat spontaneously flows from a hotter (in this example water) to a colder body (in this example human body).

The process of heat conduction depends on four basic factors: the temperature gradient, the cross section of the materials involved, their path length and the properties of those materials.

I think it is b.heat transfers to his body from the water by conduction

How many moles of hydrogen gas are generated when 4.0 moles of water react with excess calcium

Answers

Answer:

2moles of H2

Explanation:

First, let us generate a balanced equation for the reaction between calcium and water. This is illustrated below:

Ca + 2H20 —> Ca(OH)2 + H2

From the equation,

2moles of H2O produced 1mole of H2.

Therefore 4moles of H2O will produce = 4/2 = 2moles of H2.
