Using dimensional analysis How many mg are there in 8.75 X 107 kilograms?
Conversion factors:
[1000 g = 1 Kg]
[1000 mg = 1 g]
Can you please show the work
Answers
Answer:
8.75×10¹³ mg
Explanation:
From the question given above, we obtained:
Mass (in Kg) = 8.75×10⁷ Kg
Mass (in mg) =?
Next, we shall convert 8.75×10⁷ Kg to grams (g). This can be obtained as follow:
1 Kg = 1000 g
Therefore,
8.75×10⁷ Kg = 8.75×10⁷ Kg × 1000 g/1 kg
8.75×10⁷ Kg = 8.75×10¹⁰ g
Therefore, 8.75×10⁷ Kg is equivalent to 8.75×10¹⁰ g.
Finally, we shall convert 8.75×10¹⁰ g to mg. This can be obtained as illustrated below:
1 g = 1000 mg
Therefore,
8.75×10¹⁰ g = 8.75×10¹⁰ g × 1000 mg/ 1 g
8.75×10¹⁰ g = 8.75×10¹³ mg
Thus, 8.75×10⁷ Kg is equivalent to 8.75×10¹³ mg.

c

d

e

Answers
Answer:
b is constant
Explanation:
The half-life of a radioisotope is constant throughout its life cycle.
Half-life is the time taken for half of the radioactive nuclei to disintegrate.
Every radionuclide has its characteristic half-life and it is independent of the number of radioactive atoms.
The half-life does not depend on any variable. It is an inherent property of a radioactive isotope. The shorter the half-life, the faster a radionuclide decays. Nuclides with a long half life are fairly stable for a long period of time. The decay of a radioactive element is usually characterized by its half-life.Therefore, the most ideal statement about half-life is that it is constant.

Answers
Answer:
cannot be used to produce energy in reactors.
Explanation:
Currently, there is no reactor that can allow the use of nuclear fusion, although nuclear plants use nuclear fission reactors.
Nuclear fusion happens when thousands of atoms collide with each other when they are in the midst of extreme conditions of literature and pressure. This collision causes the atoms to fuse, creating another element. The process releases amounts of light and heat, promoting a high release of energy. This whole process occurs without the release of CO2 into the atmosphere, without the release of toxic waste and without the risk of explosions, which makes nuclear plants have a strong interest in building a reactor to use this type of energy. For this reason, scientists from different countries have collaborated with each other on a project called Iter, which seeks to build a reactor and achieve the first reaction in 2025.

Explanation:
The molar absorptivity of a compound at 500 nm wavelength is 252 M-1cm-1. Suppose one prepares a solution by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution. What would be the absorbance in a 3 .00 mm pathlength cell?
Answers
Answer:
The absorbance of the solution is 0.21168.
Explanation:
Given that,
Wavelength = 500 nm
Molar absorptivity = 252 M⁻¹ cm⁻¹
Number of moles = 0.00140
Volume of solution = 500.0 mL
Length = 3.00 mm
We need to calculate the molar concentration
Using formula of the molar concentration
[tex]C=\dfrac{N}{V}[/tex]
Where, N = number of moles
V = volume
Put the value into the formula
[tex]C=\dfrac{0.00140}{0.5000}[/tex]
[tex]C=0.0028\ M[/tex]
We need to calculate the absorbance of the solution
Using formula of absorbance
[tex]A=\epsilon C l[/tex]
Put the value into the formula
[tex]A=252\times0.0028\times0.300[/tex]
[tex]A=0.21168[/tex]
Hence, The absorbance of the solution is 0.21168.
The absorbance of a compound, with a molar absorptivity at 500 nm wavelength of 252 M⁻¹ cm⁻¹, prepared by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution, measured in a 3 .00 mm pathlength cell, is 0.212.
First, we will calculate the molarity of the compound, which is equal to the moles of solute divided by the liters of solution.
[tex]M = \frac{0.00140mol}{0.5000L} = 0.00280 M[/tex]
Then, we will convert 3.00 mm to cm using the conversion factor 1 cm = 10 mm.
[tex]3.00 mm \times \frac{1cm}{10mm} = 0.300 cm[/tex]
Finally, we will calculate the absorbance of the compound using the Beer–Lambert equation.
[tex]A = \epsilon \times b \times C[/tex]
where,
A: absorbanceε: molar absorptivityb: length of light pathC: molar concentration[tex]A = \epsilon \times b \times C = \frac{252}{M.cm} \times 0.300 cm \times 0.00280 M = 0.212[/tex]
The absorbance of a compound, with a molar absorptivity at 500 nm wavelength of 252 M⁻¹ cm⁻¹, prepared by dissolving 0.00140 moles of a solute in enough water to make a 500.0 mL solution, measured in a 3 .00 mm pathlength cell, is 0.212.

The Central America is near the equator could explain the above statement.
What is equator?Equator is an imaginary line that passes through the centre of the globe at 0 degrees latitude and at equal distance between the North and South Poles.
Some countries of Central America are situated near the equator. The places near equator have little seasonal variation. These places have same amount of daylight and darkness throughout the year and remain warmer year round. These places near the equator have an alternating dry and rainy seasons.

The process of water migrating from areas of low electrolyte concentration to areas of high electrolyte concentration is called diffusion.
Cerebral edema is the medical term for the swelling of the brain.
What is diffusion?Diffusion is a process where the substance or ions of from a low concentration to a high concentration. It occurs against the concentration gradient, so it needs energy.
Cerebral edema is a condition where fluid gets filled in the brain and the brain swells and make pressure on the skull called intracranial pressure.
Thus, Diffusion is the mechanism by which water moves from regions with low electrolyte concentrations to regions with high electrolyte concentrations.

1. sulfur II. hydrogen III. strontium IV. iodine
V. oxygen
Answers
Answer:
sulfur
hydrogen
iodine
oxygen
strontium
Explanation:
An atom gets larger as the number of electronic shells increase; therefore the radius of atoms increases as you go down a certain group in the periodic table of elements.
In general, the size of an atom will decrease as you move from left to the right of a certain period.
Order of increasing atomic radius:
O < H < S < I < Sr
Describe the trend of atomic radius.The atomic radius measures the separation between an atom's nucleus and its farthest electrons.
The trend across a periodAtoms' atomic radii typically decrease from left to right.As electrons are added to the same primary energy level, protons are gradually added to the nucleus. Because of the increased positive charge on the nucleus, these electrons are gradually drawn closer to it. Atomic sizes shrink as the strength of attraction between nuclei and electrons grows.The trend down the groupWithin a group, atoms' atomic radii typically increase from top to bottom. Again, the positive nuclear charge rises as the atomic number decreases inside a group. The number of major energy levels that are occupied is increasing as well, though. The orbitals from higher primary energy levels have greater sizes than the orbitals from lower principal energy levels. Atomic radius increases down a group as a result of the stronger impact of the major energy levels outweighing the increase in nuclear charge.Learn more about atomic radius here:
