is copper a renewable resource? explain your reasoning
In an electrical wire, if instead of copper, plastic wire is used. Would it conduct electricity?Justify your answer.
Answer:
No, a plastic wire would not conduct electricity. This is because plastic is an insulator that does not allow electric current to flow through it. In a wire, electrical conductivity is provided by the movement of charged particles - typically, electrons. Copper is an excellent conductor of electricity because it has a high number of free electrons that are not bound to atoms and can move through the wire very easily. However, in a plastic wire, the tightly bound electrons of its atoms do not allow for the free flow of charges, thus preventing the passage of electric current.

1. Using D10W and a vial of NaCl 4 mEq/mL, how many mL of NaCl are needed to prepare 250 mL of a
D10/NS solution?
a. 4.8mL
b. 9.6ml
c. 19.6mL
d. 154mL
To prepare 250 mL of a D10/NS solution using D10W and a vial of NaCl 4 mEq/mL, you would need 9.6 mL of NaCl. Normal saline (NS) contains 154 mEq/L of sodium chloride (NaCl). To prepare 250 mL of NS, you would need 250 mL * (154 mEq/L) = 38500 mEq of NaCl. Since the vial of NaCl contains 4 mEq/mL, you would need 38500 mEq / (4 mEq/mL) = 9625 mL = 9.6 mL of NaCl. So the correct answer is b. 9.6ml.

Which of the following is true about gravity? Select all that apply.
Answer:
A and B are the correct answers.
Answer:
A and B are correct
Explanation:
A and B are the most logical answers from the 4 given. This is because just like the moon and Earth, Earth keeps the moon in its orbit with gravity.
A gravitational force can happen with any two objects in the universe. An example of this is a passing asteroid being pulled into Jupiter's atmosphere, because of the gravitational pull. Even two asteroids can have a gravitational pull/force on each other. If there is a big asteroid with smaller asteroids surrounding it, the smaller asteroids will "follow" the larger asteroid.
C is false, because the bigger the mass the bigger the pull (gravitational)
D is also false because if the gravitational force could only exist if there was contact, logically then the moon wouldn't still be orbiting Earth. In other words "Does the moon touch the Earth?" No, it does not "Is the moon still orbiting around Earth without contact?" Yes it is
Where does most fresh water exist?
Answer:
aquifers, ice caps, and glaciers I think
Argument 1
The water in the puddle that Claire observed evaporated. The highest temperature was 32°C (90°F). Since the puddle was there in the morning and gone later in the day, it must have evaporated.
Argument 2
The water in the puddle that Claire observed evaporated. Since the highest temperature was 32°C (90°F), we know that it was a warm day. When water gets hot, it can change from liquid to gas. This is called evaporation. I think the water became so warm that it became water vapor (gas), and that’s why the puddle was gone by the afternoon.

Part 3: Writing to the People of Westfield
Dr. Yung wants you to explain what the reddish-brown substance is to the people of Westfield. As you write your argument, remember to:
state your claim about the identity of the reddish-brown substance.
use evidence from both your observations and the atomic-scale models to support your claim.
include the vocabulary words listed below in your argument.
Chapter 1 Question: What is the reddish-brown substance in the water?
Claim 1: The reddish-brown substance is the same as the substance that makes up the pipes.
Claim 2: The reddish-brown substance is the same substance as the fertilizer.
Claim 3: The reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes.
Word bank: atom, model, property, substance
Answer:
Dear People of Westfield,
As you may be aware, there has been a lot of concern about the reddish-brown substance found in the water supply. After conducting extensive research and analysis, I am here to share my findings with you.
Based on my observations and the atomic-scale models, I can confidently state that the reddish-brown substance is not the same as either the fertilizer or the substance that makes up the pipes. In fact, the reddish-brown substance has its own unique set of properties that distinguish it from these other substances.
One of the key pieces of evidence supporting this claim is the atomic-scale model of the reddish-brown substance. This model shows that the substance is made up of its own distinct atoms arranged in a specific way. These atoms have unique properties, such as their size and charge, that differentiate them from the atoms that make up the fertilizer and the pipes.
Furthermore, my observations of the reddish-brown substance also support this claim. I have noticed that the substance behaves differently than both the fertilizer and the pipe material. For example, the substance dissolves at a different rate and reacts differently to various chemicals.
In conclusion, it is clear that the reddish-brown substance in the water supply is its own unique substance, with its own distinct properties and atomic makeup. It is not the same as either the fertilizer or the substance that makes up the pipes. I hope that this explanation provides some clarity and reassurance to the people of Westfield.

When is the Law of Conservation of Mass not true? I am so confused...
Answer:
When one of the products of the equation is a gas. The gas escapes and isn't weighed and what is left is not the total mass of the system.
Explanation:
;)
Answer:
The conservation of mass does not apply if the system is open and energy escapes. However, it does continue to apply to totally closed/isolated systems. Therefore, if energy cannot escape a system then its mass cannot decrease.

Is there a relationship between CO2 levels rising and heavy precipitation? If so, what is it?
Answer:
Explanation:
Yes, there is a relationship between rising CO2 levels and heavy precipitation. As the concentration of CO2 in the atmosphere increases, it leads to a warming of the Earth's surface due to the greenhouse effect. This warming, in turn, causes an increase in the rate of evaporation of water from the Earth's surface, including from the oceans, lakes, and rivers.
This increased evaporation results in more water vapor in the atmosphere, which can lead to heavier precipitation events, including more frequent and intense rainstorms, snowstorms, and other forms of precipitation. This is because warmer air can hold more moisture, making it more likely to produce heavy rainfall.
In addition, the warming of the Earth's surface can also lead to changes in atmospheric circulation patterns, which can further increase the likelihood of heavy precipitation events in some regions.
Overall, the relationship between rising CO2 levels and heavy precipitation is complex and can vary depending on the specific location and other environmental factors. However, there is evidence to suggest that as global temperatures continue to rise due to rising CO2 levels, heavy precipitation events are likely to become more frequent and intense in many parts of the world.
Answer: Yes there is a direct relationship between CO2 and heavy precipitation. Rising in CO2 means increasing the temperature in the atmosphere which causes more water vapor evaporates into the atmosphere and which causes high rainfall or precipitation.
Explanation: Increased atmospheric CO2 levels are causing plant stomata to close, allowing plants to hold more water in their stems, reducing transpiration, and possibly impacting tropical rainfall patterns in varying ways depending on region.
How did this piece of evidence change your thinking about the channel on Mars? Explain your ideas below.
The piece of evidence changed thinking about the channel on Mars because it shows that the rock was formed next to flowing water as such rock formations exist on Earth and were formed by flowing water.
Was there flowing water on Mars ?The geologic process that could have created the channel on Mars is water moving. We can infer from the image that water running across the terrain on Mars created channels similar to those on Earth.
We can claim that the flowing of water creates the channels on Mars because when the water runs for a long period from the same region, it takes the sediments and creates channels.
