<h3><u>Answer and explanation</u>;</h3>
- <em><u>The isotope U-235 is an important common nuclear fuel because under certain conditions it can readily be split, yielding a lot of energy. It is therefore said to be 'fissile' and use the expression 'nuclear fission'.</u></em>
- <em><u>Uranium 238 on the other hand is not fissionable by thermal neutrons, but it can undergo fission from fast or high energy neutrons. Hence it is not fissile, but it is fissionable.</u></em>
- In a nuclear power station fissioning of uranium atoms replaces the burning of coal or gas. Heat created by splitting the U-235 atoms is then used to make steam which spins a turbine to drive a generator, producing electricity.
In the reaction as follows: NH2- + CH3OH → NH3 + CH3O−, NH2- is the Brønsted-Lowry base.
BRØNSTED-LOWRY BASE:
- According to Bronsted-Lowry definition of a base and acid, a base is substance that accepts an hydrogen ion or proton (H+) while an acid is a substance that donates a proton.
- According to this reaction given as follows: NH2 + CH3OH → NH3+ CH3O-
- NH2- is a reactant that accepts a hydrogen ion (H+) to become NH3+
- NH3+CH3OH is a reactant that donates hydrogen ion (H+)
- Since NH2- accepts a proton, this means that in the reaction as follows: NH2 + CH3OH → NH3 + CH3O−, NH2- is the Brønsted-Lowry base.

Answer:
Mass = 55.52 g
Explanation:
Given data:
Number of atoms of Li = 4.81×10²⁴ atom
Number of grams = ?
Solution:
The given problem will solve by using Avogadro number.
It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.
The number 6.022 × 10²³ is called Avogadro number.
For example,
1.008 g of hydrogen = 1 mole = 6.022 × 10²³ atoms of hydrogen
For Li:
4.81×10²⁴ atom × 1 mol / 6.022 × 10²³ atom
8 moles
Mass in gram:
Mass = number of moles × molar mass
Mass = 8 mol × 6.94 g/mol
Mass = 55.52 g
Answer:
- <u>Agents that can homogenize immiscible solutions are</u> milk , lotion , glue , paint ,alcohol etc.
- The primary difference between fats and oils is that, whereas oils are generally derived from plants, fats are usually derived from animals.
- Eating too much of the wrong kinds of fats will increase unhealthy LDL cholesterol of decrease healthy HDL cholesterol, such as saturated and trans fats.
- Your risk of high blood pressure, arterial hardening (atherosclerosis), heart attack and stroke may be enhanced by the imbalance of fats and oils.
- <u>Among the doctor and the patient , the patient's health is deteriorating. </u>
<u>To minimize the intake of fats and oils by suggesting them simple ways-</u>
- Eat more vegetables and fruits.
- Stop cream and cheese sauces, or use low-fat milk and cheese to make meals.
- Instead of butter or margarine, try cooking with herbs , spices, lemon juice, etc.
- Try cooking with herbs, spices, lemon juice, etc., instead of butter or margarine.
- Beware of confectionary foods, such as chocolate or pastry dishes and crisps. These are very high in fat instead consider swapping for a more balanced snack or restricting portion sizes.
<u>Explanation:</u> <u>FATS -</u>: Fats are usually derived from animals. Fats contain a larger proportion of fatty acids that are saturated. Fats at room temperature are solid.
<u> OILS -</u> Oils at room temperature are liquid. From plants, oils are extracted. A greater proportion of unsaturated fatty acids are found in oils.
