Nuclear power produces more toxic mercury than coal-burning power plants do. True Or False?

Chemistry

Answer: True  

Explanation:

Nuclear power plant produces energy by fission or fusion reactions occurring in the nuclear reactor. The energy is harnessed by the heavy metal atom nuclei like uranium. The nuclear power plant produces radioactive wastes.  It does not produce toxic substances and greenhouse gases.

The coal is a fossil fuel, which when burned generates energy in the form of heat. But it also generates pollutant toxic and gases such as carbon dioxide, carbon monoxide, sulfur dioxide, toxic metals elements such as arsenic, mercury and cadmium.  

The quantity and concentration of a mercury released by the nuclear power plant is more than the coal burning plant. Also it is released in the form of radioactive wastes. Thus capable of causing direct hazardous damages such as deadly mutation in the genome. The mercury toxicity by coal power plant will result in gastrointestinal and respiratory diseases.

Anika [276]

Answer:

5)0.53liters

6)1.634.6°c

Explanation:

using \:  charles \: law \\ v1 \div t1 = v2 \div t2

5) v1=25liters, t1=12000°c. v2=?, t2=250°c

v2=(250×25)/12000

v2=6250/12000

v2=0.52liters

6)v1=130,v2=85, t1=2500, t2=?

t2=(85×2500)/130

t2=212500/130

t2= 1634.6°c

In the reaction between CO and Fe3O4, the theoretical yield in an experiment is calculated to be 47.2 g Fe. When a chemistry stu
dusya [7]

Answer:

C. 63.3%

Explanation:

Theoretical yield = 47.2g

Actual yield = 29.9g

Percentage yield = ?

The percentage yield of a compound after chemical synthesis is the ratio of the actual yield to the theoretical yield multiplied by 100.

Percentage yield = (actual yield / theoretical yield) × 100

Percentage yield = (29.9 / 47.2) × 100

Percentage yield = 0.6334 × 100

Percentage yield = 63.34%

The percentage yield of Fe is 63.34%
