What are the steps to evaporate Copper sulfate crystals?
Answer:
copper sulfate is soluble in water its crystals dissolve in water to form copper sulfate solution. During evaporation, the water evaporates away leaving solid copper sulfate crystals behind. A solution is placed in an evaporating basin and heated with a Bunsen burner

H2 (2 as in a subscript)+ Cl2 (2 as in a subscript) = 2HCL
If the reactant contains one chlorine Molecule, Do you know how many Chlorine Atoms will be in the Product? Include Conversations Of matter in your explanation.
Answer:
2 chlorine atoms.
Explanation:
H₂ + Cl₂ → 2HCl
The Law of Conservation of Mass states that matter can neither be created nor destroyed in a chemical reaction.
If 2 molecules of Hydrogen and 2 molecules of Chlorine is present in the reactants, the same no. of atoms should also be present in the product.
∴ the no. of chlorine atoms in the product is 2.

What roles do society, politics, and economics play in science?
Discovering the roles and influence that society, politics, and economics have on science takes some practice. Sometimes these influences are not obvious but appear only after a solution to the problem has been tested over a period of time.
These articles describe conservation problems and solutions that were influenced by scientific, social, economic, or political issues. As you read each article, take note of the sections that represent these factors. You will use these articles in your assignment for this lesson.

Community Conservation

Using both of the articles, answer the questions below. You can answer questions on a word processing document and upload it for grading, or you can submit answers to questions directly. Be sure to review the grading rubric before you begin.
Summarize the scientific information that leads to conservation in each of the articles.
What social issues affected the problem or its solution in each of the stories?
How did economics delay scientists' first attempts for conservation in each story?
Describe the political actions that led to successful conservation in both stories.
Answer:
Hey mate....
Explanation:
This is ur answer.....
1A) The articles are expressing that how each field affects conservation. They also talk about problems and solutions that are influenced by social, economic or political issues.
2A) If people stop cutting down as many trees, there won’t be as many resources from that such as paper maybe the cost will go up. Companies will be mad if people stop them from doing business, cutting down trees and making money for example some experiences people had when they confronted companies went like this, "We had chief executives slamming the phone down on us. I even had people threaten to punch me." But there are a lot of good things happening such as a lot of materials are made that FSC certified so you can have a clear conscience.
3A) If people are cutting down trees, then those companies aren’t getting money then they lose job opportunities without people there doing their jobs then no products like paper can be made. Also, if trees aren’t being cut down clearing space places like houses or malls can’t be built there. There are some solutions though like what FSC certified places do is after they cut down a tree they plant a new one in that exact spot.
4A) A lot of countries are becoming FSC certified such as Russia. Just a little bit ago Russia had very little forest that was FSC certified now it's 260,000 sq. km—a quarter of its commercial forests. 40 percent—forest area of Europe and North America certified by the FSC...

Answer:
Summarize the scientific information that leads to conservation in each of the articles?
In the article “using forest wisely”, the article states that people have destroyed the forest at an alarming rate. In the absence of trees, the ecosystem will eventually die. Which causes a major issue to not only the animals who lives in the forest but also the world's population nearly a quarter. We all rely on the forest for the air we breathe and the products it provides for us. In the article “community conservation”, the article states the population of the gorillas have been decreasing. A big problem has been Poaching, it has taken a heavy toll only about 700 hundred gorillas remain in the wild.
What social issues affected the problem or its solution in each of the stories?
In the article “community conservation”, the article states there hasn’t been many tourist since there’s been a decrease population of mountain gorillas. Tourist revenues helps to fund conservation work and new infrastructure and enterprises such as tree plantations and animal habitats. In the article “using forest wisely”, the article states that Forest Stewardship Council (FSC) was created so the committee can save the forest with strict regulations and laws. Local workers are employed and help saving the environment.
Explanation:
How is it possible that heat is transferring from the water in the tank to the water in the bag, even though the water in the tank doesn’t feel hot?
Answer:
animals unlike us adapt faster to heat/cool weather or water
Explanation: Let's use fish as an example because that's the main water pet, so when you get a new fish and you have to put it in the water for about let's say 15 minutes. It's so it can adapt to the water. Water for us needs to be hot enough for us to actually feel the heat so therefore animals can adapt not only faster to heat but to cool air/water a lot faster than we can. I don't know if this helps or makes sense but it's what I know and have seen :P

7. A pool player hits a cue ball with a speed of 10 m/s. If the mass of the ball is 0.16 kg, calculate the kinetic energy of the moving cue ball. (Show your work!)
Answer: 8 Joules
Explanation:
0.16/2=0.08
10²=100
0.08x100=8
The kinetic energy of the moving cue ball is 8 Joules

Fredrick has two samples of pure water - sample X and sample Y. Sample X has a volume of 1 L and sample Y has a volume of 10 L. How do the boiling points of these two samples compare?
Group of answer choices
Sample X will boil at a lower temperature because it has less volume.
Sample Y will boil at a lower temperature because it has more volume.
Which ever sample receives heat first will have a lower boiling point.
Sample X and Y will boil at the same temperature.
Answer:
D. Sample X and Y will boil at the same temperature
Explanation:
The boiling point of a liquid is the temperature at which the vapor pressure equals the atmospheric pressure.
The boiling implies a phase change of water from liquid to vapor. This requires an input of energy in the form of heat. Since Y has a greater volume than X, Y will require a higher heat input. However, the boiling temperature will remain unchanged.
Please tell me if this is wrong Brainliest would be appreciated Hope this helps have a great day!

The weather map shows the weather conditions for one day across the United States. Based on the weather map, which city will most likely experience heavy rainstorms during the next 24 hours?
Answer:
THE ANSWER IS
C. St. Louis
Explanation:
Do you see that big, slightly curved line overlapping the united states, with little triangles in it? That represents the heavy rainstorm. If you look close enough, St. Louis is closest to one of the tiny triangles, aka the rainstorm.
WHY IT CAN’T BE THE OTHER OPTIONS:
It cannot be the other choices because they are not as close to the line as St. louis is

A student filled a shallow pan of with water and wanted to investigate waves. The student used a dropper to drip water onto the surface and then made observations. Figure one shows the student view looking down on the pan.
Which of the following statements about the waves in the pan is true?
A.Waves transfer matter
B.Waves transfer energy
C.Waves transfer matter and energy
D.Waves transfer neither matter nor energy
Answer:
B
Explanation:
Waves does not transfer matter. Waves does not add any matter but it does add energy becuase of the movment.
The water waves are mechanical waves and they transfer both matter ad energy. Therefore, option C is correct.
What are mechanical waves ?Mechanical waves are those waves which can pass through a medium only. Hence, they are not like an electromagnetic wave which passes through vacuum too.
There are two types of mechanical waves namely, transverse waves and longitudinal waves are those in which the oscillation of particles is in the direction of the wave propagation.
In transverse waves, the oscillation is in perpendicular to the direction of propagation. Water waves are transverse waves. They can transfer both energy and matter. Hence, option C is correct.

Answer:
The velocity of ball and man after catching ball is
Explanation:
Since there is no friction and no external force the momentum is conserved .
Here when man catches ball then man and ball move with common velocity .
