Correct Answer is Option C i.e. <span>production of wastes needing long-term storage.
Reason:
Most of the nuclear power plant uses nuclear fission reaction for generation of electricity. In a nuclear fission reaction, a radio-active nuclei (high atomic mass) is bombarded with fast moving projectile. This results in nuclear disintegration. The mass defect between product and reactant results in generation of energy. The daughter element generated during this event, may also be radio-active in nature. These materials have extremely high half-life. Hence, this waste product needs to be stored safely for long-time so as to minimize the risk of nuclear contamination. </span>
Answer:
Jane has 2.77 * 10^20 molecules cholesterol in 1 dL of blood
Explanation:
<u>Step 1:</u> Given data
Molar mass of Cholesterol = 386.654 g/mol
Jane has a cholesterol of 178 mg/dL
<u>Step 2:</u> Calculate mass of cholsterol in 1 dL
178 mg/dL means in 1 dL she has 178 mg cholesterol or 0.178 grams
<u>Step 3</u>: Calculate number of moles of cholesterol
Number of moles = mass of cholesterol / molar mass of cholesterol
Number of moles = 0.178 grams / 386.654 g/mol = 4.6 * 10^-4 moles
<u>Step 4: </u>Calculate number of molecules
Number of molecules = 4.6 * 10^-4 mol * 6.022 *10^23 / mol = 2.77 * 10^20 molecules
Jane has 2.77 * 10^20 molecules cholesterol in 1 dL of blood
The volume of pure sulfur would be 62.8
Answer: A chemical reaction that stores energy is called an endothermic reaction. More energy might be released as products form than the energy needed to break the reactants apart.
