Explanation:
Name the four different types of Spheres belonging to Earth and give examples of Renewable resource and the Biotic factors that exist in those spheres. There are three Abiotic (Non Living) spheres and the Biotic (Living)Biosphere exist within the three of the others
Write a short summary of the renewable resources in each sphere and explain how the biosphere interacts within the three of them
Answer:
Everything in Earth's system can be placed into one of four major subsystems: land, water, living things, or air. These four subsystems are called "spheres." Specifically, they are the "lithosphere" (land), "hydrosphere" (water), "biosphere" (living things), and "atmosphere" (air).

how can an xray image show differences between bone and soft tissues, such as muscles and lungs? How might the atoms that make up bones be different from the atoms that make up soft tissues?
Answer with Explanation:
1. An "x-ray image" shows the difference between the bones and soft tissues because the bones appear white in color while the soft tissues appear gray in color.
2. The reason behind the difference in the appearance of bones and soft tissues on the x-ray film is their density. Bones are denser than soft tissues, which means that its atoms are closely-knitted when compared to the soft tissues that are far apart from each other. This allows the x-ray radiation to be absorbed by the bone while it passes through most of the soft tissues.
This is the reason why pregnant women are advised not to undergo an x-ray examination because the fetus is denser and it will surely absorb the x-ray radiation.
An X ray is a X wave radiation that can penetrate from a high EMR and has wavelengths that are shorter than the UV rays. The concept of X rays where discovered in 1895.
The X ray image shows the difference between bones and the soft tissues. As the bones appear to be white in color and soft tissues appear grey in color. As lungs also consists of bones they can vividly shown. Due to the bones being made of calcium they are different form the atoms that makes the soft tissues.Learn more about the x-ray image show differences between bone and soft.

4) What is one advantage of using non-renewable resources?
Answer:
The main advantages of non-renewable energies is that they are abundant and affordable. For example, oil and diesel are still good choices for powering vehicles. Non-renewable energy is cost effective and easier to product and use.

5.Calculate the number of moles of 18.0 dm3 of carbon monoxide (CO) at rtp.
Answer:
0.81mole
Explanation:
Given:
Volume of carbon monoxide = 18dm³
Unknown
Number of moles of carbon monoxide = ?
Solution:
To solve this problem;
1 mole of any gas at rtp occupies a volume of 22.4dm³
So;
x mole of carbon monoxide will occupy a volume of 18dm³ at rtp
22.4x = 18
x = [tex]\frac{18}{22.4}[/tex] = 0.81mole
If the heat of combustion for a specific compound is −1160.0 kJ/mol and its molar mass is 86.47 g/mol, how many grams of this compound must you burn to release 541.20 kJ of heat?
Answer:
40.34 g
Explanation:
First, we divide the heat to release by the heat of combustion to obtain the required moles of compound:
541.20 kJ/(1160.00 kJ/mol) = 0.4665 mol
So, we have to burn approximately 0.47 mol of the compound. We convert the moles to mass in grams by using the molar mass:
mass = molar mass x moles = 86.47 g/mol x 0.4665 mol = 40.34 g
Therefore, you must burn 40.34 grams of the compound to release 541.20 kJ of heat.

Answer:
Contribute evidence; help us understand how people use resources.
Explanation:
Environmental science can be defined as an interdisciplinary field of science that comprises of chemistry, economics, engineering, zoology, geography, geology, biology, ecology, physics, etc., used for the study and understanding of various environmental factors, issues in relation to human life.
Many disciplines are involved in environmental science, including chemistry and biology which contribute evidence and economics and political science which help us understand how people use resources in the production of goods and services to meet the need or requirements of consumer. These resources include land, labor, entrepreneurship and capital.

Which element creates an ion who is LARGER in size than the original atom? Rb Rn S Ca
Answer:
The element S creates an ion which is larger in size than the original atom.
Explanation:
The atomic radius of elements is a measure of the size of atoms of elements. The atomic radius is defined as one-half the distance between the nuclei of identical atoms that are bonded together. Atomic radius increases on going down the group in the period table but decreases on going rom left to right across a period in the periodic able. The increase in atomic radius on going down the group is due to the addition of an extra electron shell to successive atoms of elements in a group. However, atomic radius decreases across a period due to increase in the positive charge of the nucleus of elements in the same period.
When atoms of elements form ions, the ionic radius of the resulting ion can either increase or decrease. For positive ions, the ionic radii decreases due to loss of electron increasing the attraction of the positive nucleus or even a complete loss of an electron shell. For anions, ionic radii increases due to gain of electrons which results in greater repulsion among neighboring electrons.
Among the elements given, rubidium (Rb), and calcium (Ca) for cations, hence, their size becomes smaller. Radon, Rn, being a noble gas is relatively inert, but forms positive ions when it does take part in reactions. Sulphur, S, however forms an anion, S²⁻, hence, its size increases.
