Only 0.7% of natural uranium is 'fissile', or capable of undergoing fission, the process by which energy is produced in a nuclear reactor. The form, or isotope, of uranium which is fissile is the uranium-235 (U-235) isotope. ... Most is then converted into uranium hexafluoride, ready for the enrichment plant.
Answer: as copper has lower electrode potential value than hydrogen, it could be reduced by hydrogen.
Explanation: hydrogen has zero reduction potential while Cu has +0.34V and Al has -1.66 V .
SO in electrochemical series who has most negative or less reduction potential value tends to be a good reducing agent than the other.
Hope it helps...
Answer:
True
Explanation:
The greenhouse effect is the process whereby there is radiation from a atmosphere planet and the planet increase the temperature of the planet's surface to a temperature above normal.In this process the Earth's atmosphere becomes thicker with the influence substances such as gases
and the radiation coming from the sun is trapped, then the Earth becomes warmer. Green house effect is seen in global warming.
Carbon neutral can be described as a process of removing huge amount of carbon dioxide from the atmosphere in order to achieve zero carbon neutrality.It is also reffered to as carbon neutrality, and this can be achieved by actions of organizations, businesses and individuals .
Carbon neutral can be achieved in two ways;
: 1.) Maintaining a balance between carbon dioxide emissions and carbon removal by means of the process called carbon offsetting
2 ) the process of removal of carbon dioxide from the atmosphere in order to balance up emissions in another place.
Carbon positive is crucial to increase the positive influence of our daily activities on climate change and our resources.
while reduce the negative effect of our activities and business on evironment.
Therefore, the practice of making operations "carbon neutral" is a way to offset whatever damage is being done to the environment due to greenhouse gas emissions by purchasing credits from "carbon-positive" projects to balance out emissions is true because the harmful gasses that is been released to the atmosphere is balance up by the carbon neutral process hence the reduction in green house effect.
Quartz is a substance because the material has uniform properties throughout and is held together via chemical bonds.
