Answer:
intruducing nuclear in a country like nepal where the knowledge of nuclear science is limited is a major task.
Explanation:
(maybe it will help if not sorry because my answer is wrong)
Nepal is a landlocked country that has been facing challenges in meeting its energy demand. The country is heavily dependent on imported fossil fuels, which are expensive and have negative environmental impacts.
Nuclear energy is the energy that is released from the nucleus of an atom through a process called nuclear reaction. Nuclear reactions can occur spontaneously or can be induced by bombarding the nucleus with particles such as neutrons.
However, Nepal currently does not have any nuclear power plants, and the country has not developed any nuclear energy infrastructure. Therefore, the development of nuclear energy in Nepal would require significant investment in terms of time, money, and human resources. Additionally, there are concerns about the safety and security of nuclear energy, and these issues would need to be addressed before nuclear energy could be developed in Nepal.
Despite these challenges, there are some potential benefits to the development of nuclear energy in Nepal. Nuclear energy has the potential to provide a reliable source of energy that is not dependent on imported fossil fuels. Additionally, nuclear energy is a low-carbon source of energy that could help Nepal reduce its greenhouse gas emissions and mitigate the impacts of climate change.
In conclusion, the development of nuclear energy in Nepal is a complex issue that requires careful consideration of the potential benefits and risks. While nuclear energy could provide a reliable and low-carbon source of energy, there are significant challenges that would need to be addressed before nuclear energy could be developed in Nepal.

Explanation:All atoms are made up of particles known as protons, neutrons, and electrons.
Mass Number
The mass number of an atom is most commonly given in amus. Amu stands for atomic mass unit. In an atom, a proton = 1 amu, a neutron = 1 amu, and an electron = 0 amu. Since atoms are so small, it is hard to measure a singular in normal units such as grams. So, instead, scientists use amus. Comparatively, protons and neutrons are far larger than electrons. This is why electrons are given a mass of 0 amu. Of course, electrons do technically have mass, but that mass is so small that it is negligible in many calculations.
Counting Neutrons
When given the atomic number and mass number, it is easy to find the number of neutrons. The atomic number of an element tells you how many protons there are. The mass number gives you the mass of the atom in amus; this number is equal to protons + neutrons. This means that mass number - atomic number = neutron number.
So, we can set up a very simple equation to find the number of neutrons.
1 - 1 = 0 neutrons.Most hydrogen atoms have no neutrons.

John Dalton was born in a poor weaver's family in 1766 in England. He began his career as a teacher at the age of twelve. Seven years later he became a school principal. In 1793, Dalton left for Manchester to teach mathematics, physics and chemistry in a college. He spent most of his life there teaching and researching. In 1808, he presented his atomic theory which was a turning point in the study of matter.
Dalton's Atomic Theory:According to Dalton's Atomic theory, all matter whether an element, a compound or a mixture is composed of small particles called atoms.
The postulates of this theory may be stated as follows:
All matter is made of very tiny particles called atoms, which participate in chemical reactions.Atoms are indivisible particles, which cannot be created or destroyed in a chemical reaction.Atoms of a given element are identical in mass and chemical properties.Atoms of different elements have different masses and chemical properties.Atoms combine in the ratio of small whole numbers to form compounds.The relative number and kinds of atoms are constant in a given compound.Which words correctly describe CO2?

The kcal required for one year is 730kcal (kilo calories).
A calorie is a unit of energy measurement. Typically, the energy content of meals and beverages is determined in terms of calories. You must consume fewer calories each day than your body uses up in order to lose weight. On the other hand, in order to gain weight, you must eat more calories than you burn.
The daily caloric needs of adult women range from 1,600 to 2,200. Estimates for men range from 2,000 to 3,200 per day. The low end of the range may be ideal for you if you move very little or not at all during the day. If you are very active throughout the day, the high end of the range can better match your needs. The number of calories we require decreases as we age.
The kcal required for one year is:

how much water should be added to 28 ml of 15% alcohol solution to reduce the concentration to 14%?
The amount of water that should be added to 28 ml of 15% alcohol solution to reduce the concentration to 14% is: 2 ml
To solve this problem, the formula and the procedure that we have to use is:
c1 * v1 = c2 * v2
Where:
c1= concentration of the concentrated solutionv1 = volume of the concentrated solutionc2 = concentration of the diluted solutionv2 = volume of the diluted solutionInformation about the problem:
c1 = 15%v1=28 mlc2 = 14%v2=?amount of water should be added=?Applying the dissolution of concentrations formula and clearing the volume of the diluted solution (v2) we get:
c1 * v1 = c2 * v2
v2 = (c1 * v1)/ c2
v2 = (15% * 28 ml)/ 14%
v2= 30 ml
In order to know how much water should be added we have to subtract 28 ml from the volume of the diluted solution:
amount of water should be added = v2 - v1
amount of water should be added = 30 ml - 28 ml
amount of water should be added = 2 ml

which would least strongly attract electrons from other atoms in a compound? elements of group 1 elements of group 2
Elements from group 1 have the least chances to attract electrons due to their low electronegativity.
The atom's tendency to attract electrons in a molecule is known as electronegativity. The trend of electronegativity on the periodic table is as follows:
electronegativity increases across a period and decreases down a group.This means that the least electronegative element is from group 1 elements, specifically Cesium and Francium which have electronegativity of 0.79 and 0.70, respectively. In general, group 2 elements have higher electronegativity compared to group 1 elements.
