34. Explain how dimensional analysis is used to solve
problems.
By understanding conversion factors and how they are related to each other we can use dimensional analysis to solve problems.
Dimensional Analysis is a step by step approach to solving problems in Physics, Chemistry , and Mathematics. It involves having a clear knowledge and understanding to be able to convert a given unit to another in the same dimension using conversion factors and knowing how they are related to each other.
For instance, In Chemistry, we want to Convert 120mL to L.(note that ml stands for millilitres and ;L stands for litres)
Or first approach will be to write out the conversion factor related to our problem which is
1000ml =1L
such that 120ml = (we cross multiply))
giving us 120ml x 1L/1000ml =0.12L
This same process is applied to convert any type of dimensional analysis problems be it physics or mathematics.

Why Farmers kill the silkworm inside the cocoon .
Answer:
It allows the completion of the metamorphosis of the silkworm to its moth stage, whereas most silk harvesting requires the silkworms to be killed in their cocoon stage. No animals suffer or die for the silk to be produced, making it a favorable alternative to normal silk for those who do not believe in harming animals.

What is scientific notation?Scientific notation is a way of representing a quantity as a number having significant digits that are necessary for a specified degree and multiplied by ten to the power.
The general form of scientific notation can be written as [tex]N \times 10^{a}[/tex].
A significant digit is that digit in a number which adds to its precision. A significant includes all nonzero numbers, zeros between significant digits, and zeros represent to be significant while leading and trailing zeros are not significant digits as they exist only to represent the scale of number.
Given, using the scientific notation method we can write the scientific notation of the distance of 671,030 km.
The number 671,030 km can also be written as 6.71030 ×10⁵ km.
Therefore, the correct way to write this distance in the scientific notation of 671,030 km is 6.71030 ×10⁵ km.

do all types of energy have the same amount of energy
Answer:
Light is one type of radiant energy. Sunshine is radiant energy, which provides the fuel and warmth that make life on earth possible. Thermal energy, or heat, is the energy that comes from the movement of atoms and molecules in a substance. Heat increases when these particles move faster. Geothermal energy is the thermal energy in the earth.

Explanation:
just trying....hope that helps
1.6 grams of oxygen will react with 2.4 grams of magnesium.
Explanation:
Given:
2.4 grams of magnesium.
The reaction between magnesium and oxygen:
[tex]2Mg+O_2\rightarrow 2MgO[/tex]
To find:
The mass of oxygen required to react with 2.4 grams of magnesium.
Solution:
The mass of magnesium = 2.4 g
Moles of magnesium =[tex]\frac{2.4 g}{24.305 g/mol}=0.0987 mol[/tex]
[tex]2Mg+O_2\rightarrow 2MgO[/tex]
According to the reaction, 2 moles of magnesium reacts with 1 mole of oxygen, then 0.0987 moles of magnesium will react with:
[tex]=\frac{1}{2}\times 0.0987 mol=0.04935\text{mol }O_2[/tex]
Moles of oxygen required = 0.04935 mol
The mass of 0.04935 moles of oxygen :
[tex]=0.04935\times 31.999 g/mol=1.579 g\approx 1.6 g[/tex]
1.6 grams of oxygen will react with 2.4 grams of magnesium.

There are three stable forms of neon: neon-20, neon-21, and neon-22. Which statement is true?
Answer:
three stable isotopes
Neon has three stable isotopes: 20Ne (90.48%), 21Ne (0.27%) and 22Ne (9.25%). Ne and 22Ne are partly primordial and partly nucleogenic (i.e. made by nuclear reactions of other nuclides with neutrons or other particles in the environment) and their variations in natural abundance are well understood.
The statement that is true is the charge of all isotopes are same. The correct option is D.
What are isotopes?Isotopes are members of an element family that have the same number of protons but differ in terms of neutrons.
The atomic number of an element on the Periodic Table is determined by the number of protons in its nucleus.
There are three isotopes of neon. Since there is no significant global production of these isotopes, the more plentiful 20Ne and 22Ne are essentially all primordial.
Isotopes can form naturally through radioactive decay of a nucleus or unnaturally by bombarding a stable nucleus with charged particles in a nuclear reactor using accelerators or neutrons.
Thus, the correct option is D as they all have same charge.
