Jason is researching the dangers and benefits of nuclear power. He found the following information. Source 1: Nuclear energy red

uces the amount of fossil fuels burned. This reduces the amount of pollution produced. It also requires less fuel to create energy. This makes it a cheaper option for providing electricity. Source 2: Nuclear power plants create radioactive waste, which is dangerous. This waste poses a hazard to the public if it is not stored properly. Accidents can occur at nuclear power plants, which could cause a disaster. Which statement best synthesizes the information he found?
A. Nuclear power plants can cause danger to the public because nuclear waste is hazardous, and accidents at a plant could cause a disaster.

B. While an accident at a nuclear power plant could cause an ecological disaster, the same type of risk is found in power plants that use fossil fuels to produce electricity.

C. Although nuclear power can provide cheaper electricity while producing less pollution, the risk of nuclear waste and the potential for a disaster should be considered.

D. The benefits of nuclear power plants are that they can reduce the amount of pollution created by fossil fuels. They can also provide electricity at a much lower cost than fossil fuels.

Answer: C. Although nuclear power can provide cheaper electricity while producing less pollution, the risk of nuclear waste and the potential for a disaster should be considered.

Explanation:

The nuclear power plants uses the radiation energy to cause fission of heavy atoms. The energy is produced in the form of thermal energy. The nuclear power plants do not produce, carbon dioxide and other pollutants in the environment, thus these do not cause pollution in the environment. The radioactive waste are highly mutagenic in nature this causes deadly mutations in the living beings. Thus a risk is associated with the generation of energy in the nuclear power plant.

Why do atoms of elements take part in chemical reaction?​
Marina CMI [18]

Explanation:

During a chemical reaction, the atoms of the original substances gain, lose or share their electrons with those of the substances with which they are reacting. The reaction creates new substances made up of a new combination of atoms and a different configuration of electrons.

Acetylene, C2H2, can be converted to ethane, C2H6, by a process known as hydrogenation. The reaction is C2H2(g)+2H2(g)?C2H6(g)
Alecsey [184]

Answer:

Keq =1.50108

Explanation:

The given reactionis

 C₂H₂(g) +2H₂(g) -------------> C₂H₂(g)

   ΔG0 f=ΔG0f n (products) - ΔG0f n (reactants )

              = -32.89 kJ/mol - (209.2 kJ/mol+2*0.0 kJ/mol)

              = - 242.09kJ/mol

   ΔG= -RTlnKeq

   ln Keq = -ΔG/RT

           =-(- 242.09kJ/mol ) / 2 k cal /mol*298 K

           =0.406

    Keq =e0.406

         Keq =1.50108

A scientist observed a 5-mL sample of an unknown substance. It is a blue liquid with a density of 1.2 g/cm. the substance reacts
LenaWriter [7]
Characteristic properties can be used to describe and identify the substances, while non-characteristic properties, although can be used to describe the substances, cannot be used to identify them.

Temperature, mass, color, shape and volume are examples of non-characteristic properties.

Density, boiling point, melting point, chemical reactivity are examples of characteristic properties.

List of the properties observed by the scientist:
-----------------------------------------------------------------
Property                                     Type of property
----------------------------------------------------------------
Volume: 5 ml                              non-characteristic
----------------------------------------------------------------
Color: blue                                 non-characteristic
----------------------------------------------------------------
State: liquid                                characteristic
------------------------------------------------------------
density: 1.2 g/cm                        characteristic
------------------------------------------------------------
Reaction: reacts with CO2         characteristic

What is the Bayer process explain it
Vlada [557]

Answer:

The Bayer process is the principal industrial means of refining bauxite to produce alumina (aluminium oxide) and was developed by Carl Josef Bayer. Bauxite, the most important ore of aluminium, contains only 30–60% aluminium oxide (Al2O3), the rest being a mixture of silica, various iron oxides, and titanium dioxide.
