Based on the graph, it can be concluded that the isotope which is most likely to be found with 6.25% of its original amount in 6 billion years is
Uranium-238
Thorium-235
Potassium-40
Rubidium-87
Potassium is most likely to be found with 6.25% of its original amount in 6 billion years because the half life of Potassium-40 is 1-1.5 billion years in graph. Thus the correct option is C.
If it half in 1 to1.5 billion years = 50% gain
1-1.5 billion years = 25%. gain
If we do that 2 more times we will get 12.5% and then 6.25% gain.
What is half life?
Half life is defined as the time required for half of the atoms of a radioactive substance to become disintegrated.
Our estimate is about 1-1.5 billion years so repeating that about 4 times we get around 4-6 billion years for it to gain 6.25%. From this it can be concluded that Potassium-40 as since it comes the closest to remaining at 6.25% its original amount after approximately 6 billion years.

3. What would be an example of deposition?
Answer:
frost
Explanation:
Frost is the deposition of water vapour from humid air or air containing water vapour on to a solid surface. Solid frost is formed when a surface, for example a leaf, is at a temperature lower than the freezing point of water and the surrounding air is humid.
In sub-freezing air, water vapour changes directly to ice without first becoming a liquid. This is how frost and hoar frost form on the ground or other surfaces. Another example is when frost forms on a leaf.

Compared to many other liquids, water has a high heat of vaporization, which means a relatively large amount of heat must be added to the water before the water molecules are moving fast enough to escape the surface as a gas. Which of the following explains why water has a high heat of vaporization?
A Adding heat to the water causes the molecules to move around, and the motion keeps pushing them back below the waters surface
B As water molecules heat up they tend to form more hydrogen bonds with each other, making it difficult for any of the molecules to vaporize.
C Water molecules have a relatively high molecular weight compared to other molecules, so more energy is needed for the water molecules to vaporize.
D Enough heat must be added to water molecules' hydrogen bonds to break the bonds and provide the molecules enough energy to escape the surface..
Answer:
D
Explanation:
Water has a fairly high specific heat, which means that enough heat must be added to it to break the hydrogen bonds between the molecules, allowing them to move freely from each other and escape the water's surface.

13. Give one use for ethyne.
Answer:
Ethyne is useful for artificial ripening and preservation of fruits. It is useful in acetylene lamps to generate light. Ethyne is used to prepare various organic compounds. It is also useful to manufacture important organic compounds like acetic acid, acetaldehyde, ethyl alcohol and polymers like PVC, etc.
Explanation:
Since ethyne burns with a very hot flame, one of its most notable applications is in oxyacetylene gas welding and oxyacetylene gas cutting. When ethyne is subjected to combustion with oxygen, the flame created is known to have a temperature of roughly 3600 Kelvin.

The san marcos salamander, eurycea nana, is a light reddish-brown translucent salamander about 2–5 cm in length. E. Nana is found only in spring lake and a portion of the san marcos river. Which human activity would most likely decrease the ability of the salamanders to survive?.
Human activity would likely decrease the salamanders' survivability is the growth of cities, which has led to greater use of water by people and increased problems of water pollution and sludge buildup.
What leads to the disappearance of the species?Reducing the flow of water from springs is the biggest threat to the survival of Salamandra San Marcos and other animals and plants dependent on the springs. The growth of cities has led to greater use of water by people and has increased problems with water pollution and sludge buildup. The introduction of non-native species is also a threat because they can destroy aquatic vegetation, attack endangered animals or compete with them for food.
With this information, we can conclude that human activity would likely decrease the salamanders' survivability is the growth of cities, which has led to greater use of water by people and increased problems of water pollution and sludge buildup.
