Answer:
The energy absorbed in the first move is greater than the energy released in the second move.
Explanation:
The greater the level number the greater the energy.
A movement up a level requires energy so energy id absorbed.
Dropping down a level releases energy.
A. NUCLEAR FUSION is the combination of two atomic nuclei in order to create an atom that in turn creates energy.
A.1 DISADVANTAGES
1. Expensive Construction Costs- To be able to put up such powerhouse, it needs ostentatious financial support to create a facility and gather experts and scientists.
2. Energy Input vs Energy Output- To be able to fuse the two nuclei together, there is a great demand for high levels of heat. Thus to be able to produce large amount of energy, it also needs a large amount of thermal energy which is not reasonable enough.
A.2 ADVANTAGES
1. Barely Any Waste- the only by product of nuclear fusion is helium and it is non toxic. This does not cause any harm to the environment and to people.
2. Unlimited Fuel- All of the components needed to produce energy can be made. Deuterium, which is the main ingredient needed to supply a truly unlimited and sustainable energy supply, can be distilled from the sea water.
B. NUCLEAR FISSION- refers to the process of splitting of the nucleus of an atom into several smaller particles to produce free neutrons and lighter elements.
B.1 DISADVANTAGES
1. It can be dangerous for employees- Radiation which is one of the byproducts of nuclear fission can be harmful to the personnel working within its premises.
2. It has high initial expenses- Nuclear power plants needs a specialized equipment for it to become functional.
B.2 ADVANTAGES
1. It helps minimize environmental pollution- Nuclear power plants can produce large amounts of energy while consuming relatively minimal amount of fossil fuel. To explain further, consumption and usage of fossil fuel poses adverse effect in the environment because it can emit carbon dioxide and other harmful chemicals.
2. It helps reduce global warming- If the world would opt for nuclear fission, then there would be less greenhouse gasses in the atmosphere. This in turn would mitigate global warming.
Answer:
Van der waal's force of attraction
Explanation:
Van der waal's force of attraction
Forces of Van der Waals involve attraction and repulsion among atoms, particles, and surfaces as well as many other intermolecular forces. These vary from covalent and ionic bonding in that they are caused by similarities in surrounding particle fluctuating polarizations (a result of quantum dynamics).
2,2-dichloroheptane because we have two Cl we should use the prefix ''di'' and the numbers "2" and "2" indicated that the two functional groups are located on the same second carbon
In the equation given above, there is conservation of MASS, CHARGE AND ENERGY.
These three parameters are usually conserved during the course of chemical reactions. When any of these parameter experience a reduction during the course of chemical reaction, such loss is always gained by other elements involved in the same reaction, so that at the end of the day, they are not considered as lost.
