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.

You want to minimize an objects thermal energy loss on a cold day. How does heat energy transfer affect thermal energy loss?
san4es73 [151]

Answer:

4- A material that transfers heat energy more easily than another material will experience a greater rate of thermal energy loss than an object that does not transfer heat energy easily.

Explanation:

Thermal energy loss has to do with loss of heat energy by a body to another body or its environment. The aim of the process is usually the attainment of thermal equilibrium between the body and its environment.

On a cold day, a material that transfers thermal energy more easily will loose thermal energy faster than an object that does not transfer thermal energy. The rate of heat transfer of a body determines its rate of loss of thermal energy.

Lithium arsenate (Li3AsO4) and iron nitrate (Fe(NO3)3) are dissolved in water. What precipitate would you expect to form? what i
Alla [95]

Answer:

  • CO₃²⁻ +  H₂O <---------------->  HCO₃⁻ + OH⁻
  • The chemical formula of the precipitate is Fe(OH)₃

Explanation:

  • Fe(NO₃)₃ and K₂CO₃ are strong electrolytes and completely dissociate in water. Carbonate ions is a weak base and combine with water to form hydroxide ions (OH⁻), CO₃²⁻ +  H₂O <---------------->  HCO₃⁻ + OH⁻
  • Ferric, Fe (III), combines with these hydroxide ions to form insoluble precipitates. Fe(OH)₃ is only partially soluble i.e., it does not completely dissociate in water. When the solutions of Fe(NO₃)₃ and K₂CO₃ are mixed, Fe(OH)₃ precipitates out due to the strong electrostatic attraction between Fe (III) and hydroxide ions.

Consider the following voltaic cell:(j) In which direction do anions within the salt bridge move to maintain charge neutrality?
aniked [119]

In order to maintain neutrality, the negatively charged ions in the salt bridge will migrate into the anodic half-cell. A similar (but reversed) situation is found in the cathodic cell.

<h3>What purpose does a salt bridge serve in an oxidation process?</h3>

Anions (negatively charged particles) are added to the solution of the oxidation half of the cell by the salt bridge, and cations (positively charged particles) are added to the solution of the reduction half of the reaction. 

<h3>What purpose does the salt bridge serve in a galvanic cell?</h3>

For instance, KCl, AgNO3, etc. In a galvanic cell, such as a voltaic cell or Daniel cell, salt bridges are typically used. A salt bridge's primary job is to assist in preserving the electrical neutrality of the internal circuit. Additionally, it aids in keeping the cell's response from reaching equilibrium.

at standard pressure, what is the temperature at which a saturated solution of NH4Cl has a concentration of 60g NH4CL/100 g H2O
Nataliya [291]

Answer: Temperature = T, unknown

Saturated Solution, NH4Cl concentration = 60g/100g H2O = 0.6g NH4Cl/g H2O

Assume density of H2O = 1 g/ml

m = 0.6g NH4Cl/g H2O / 1 g/ml

m = 0.6g NH4Cl/ml

See the table of saturated solutions and identify the temperature at which the concentration of NH4Cl is 60g/100g H2O.

Explanation:  The line on the graph on reference table G indicates a saturated solution of NH4CL as a concentration of 60. g NH4 Cl/100. g H2O
