On May 26, 1924, the U.S. government enacted the eugenics-inspired Immigration Act of 1924, which completely prohibited immigration from Asia. The law reflected the desire of Americans to isolate themselves from the world after fighting World War I in Europe, which exacerbated growing fears of the spread of communist ideas. It also reflected the pervasiveness of racial discrimination in American society at the time.
<u>Answer</u>:
When Uranium-238 decays, it emits 8 Alpha particles and 6 beta particles before finally becoming the stable daughter product. The atomic number and mass number of the daughter product is 92 and 234 respectively.
<u>Explanation</u>:
In the process of decay of Uranium-238, it emits alpha particles, and the resultant product is Thorium-234, which turns into Protactinium-234, and this Protactinium-234 undergoes the beta decay to form the Uranium-234.
As per the question, a stable daughter product is created after the emission of alpha and beta particles, this implies that Uranium-234 is a stable product after the decay of Uranium-238. Therefore, the atomic number is 92 (number of protons) and the mass number is 234 (protons+neutrons) which is also the element of the naming.
because the bottom of the ocean is basically unreachable without the right equipment.
Answer:
The following is NOT part of the definition of a mineral: c. can be produced by natural or laboratory processes. Is glacial ice a mineral? d. Yes. Which type of bonds results when two atoms share electrons? d. Covalent
Explanation:
Mineral are composed of specific chemical elements. The are organized and their atomic structure forms crystals. They occur naturally and they are associated with rocks. The reason why they are inorganic is because they do not contain carbon, however, they can be produced by organic processes. Therefore, c. is NOT part of the definition of a mineral. Following the same principles, ice is considered a mineral because it is composed of one single chemical molecule (H2O), it occurs naturally and it contains a well organized crystal structure. The process of sharing two atoms is called covalent bond. In an ionic system, the electron is transferred to another atom so the concept of sharing is limited to the covalent bond.
Answer:
Lack of technocrats.
Explanation:
There is a widely known phrase in mining industry in Africa, its called the "resource curse". In countries like Nigeria, which produces mammoth amount of Oil all year round, the proceeds from oil is not evenly distributed to better the lives of the masses. Profits derieved from oil is expected to help fund education and training of expats. It is not the case. Thereby, we hear of the oil curse.
It is widely believed and statististically proven that Africa lacks adequate and capable technocrats to harness its vast resources.
Africa owns the resources and the West have the brains to harness them. The Western countries have the right technologies and financial capabilities to explore and produce oil in Africa.
Africa is not as technologically bouyant as the West and does not have the right structure to tap its vast oil reserves. Technologies have to constantly be imported from foreign countries. Most companies believes that it is cheaper to import foreign technocrats with an excellent track record than to start training new ones and deploy them to work in their various climes.
Although, there has been a rigorous drive through indigenous policies to bring up more Africans into the oil industry.
