Answer:

The answer to your question is below

Explanation:

a) CI Chlorine is located in group VIIA, so its must gain one electron to be stable.

b) Se Selenium is located in group VIA, it must gain 2 electrons to be stable.

c) N Nitrogen is located in group VA, it must gain 3 electrons to be stable.

d) I Iodine is located in group VIIA, so it must gain 1 electron to be stable.

e) S sulfur is located in group VIA, so it must gain 2 electrons to be stable.

how much energy would it take to heat a section of the copper tubing that weights about 660.0 gram, from 12.93 degree Celsius to
expeople1 [14]

Answer:

                      Q  =  2647 J

Explanation:

                    Specific heat capacity is the amount of energy required by one Kg of a substance to raise its temperature by 1 °C.

In thermodynamics the equation used is as follow,

                                                 Q  =  m Cp ΔT

Where;

           Q  =  Heat  =  ?

           m  =  mass  =  660 g

           Cp  =  Specific Heat Capacity  =  0.3850 J.g⁻¹.°C⁻¹

           ΔT  =  Change in Temperature  =  23.35 °C - 12.93 °C  =  10.42 °C

Putting values in eq. 1,

                            Q  =  660 g × 0.3850 J.g⁻¹.°C⁻¹ ×  10.42 °C

                            Q  =  2647 J

Which of these safety features aims to keep nuclear radiation contained
rewona [7]

The safety feature aimed at keeping nuclear radiation contained is steel-reinforced concrete.

<h3>What is nuclear power plant?</h3>

A nuclear power plant is a building with reactors that contain controlled nuclear reactions to produce energy.

Nuclear power plants are able to generate warm water by using atomic properties of matter  (i.e.,m the process of nuclear fission), which is in turn converted into steam to move turbines.

The walls of nuclear power reactors are composed of steel-reinforced concrete in order to avoid radiation release.

In conclusion, the safety standard property that maintains nuclear radiation contained is steel-reinforced concrete.
