how is the volume of a solution used in calculating concentration?​

Answers

Answer 1

Answer:

Explanation:

Concentration is defined as mols of a chemical / volume. So volume tells you what the chemical is in.

There are other ways of defining concentration, but most of them have to do with units of volume in the denominator.

eg Concentration = grams / Liter

% solvent = grams or moles / amount of solvent (solvent is a volume)

I take a medication that is 5% active ingredient. That means that the solute is 5% of the solution and water (in this case) is 95% of the solution.

So in 100 mL of solution, 5 grams of the active ingredient is put in 95 grams of water.

Just as a note (and I don't care about it, but someone might), this looks like it should be in chemistry.

5. During a park protest, a speaker tells the crowd to tear down the park fences. He is arrested. Are
his actions protected by the First Amendment? Why or why not?

Answers

Answer:

No his actions are not protected by the first amendment.

Explanation:

The first amendment only gives you the freedom of speech, religion, and press when you are peaceful. You are allowed to peacefully protest against something, but once you start to break the law (or property in this matter) the first amendment is no longer a form of protection.

The First Amendment protects free speech, but there are limits based on potential harm or danger. Encouraging actions like tearing down park fences may not be protected under the First Amendment.

While the First Amendment broadly safeguards freedom of speech, it does not protect speech that incites illegal activity or poses a clear and present danger. The Supreme Court has established that incitement to imminent lawless action is not covered by the First Amendment.

In this particular case, the speaker's directive to destroy the park fences could be seen as directly promoting vandalism or destruction of property, which are criminal actions.

Animals are eukaryotes i.e they have membrane bound organelles in their cells. They are multicellular organisms with different cells organised to perform specific life functions. Group of cells that serves a specific purpose is called Tissue. Group of tissue with a specific function is an Organ. Organs that provides a specific purpose are called Systems. Most animals have levels of organisation for their multicellular body.

All animals are heterotrophs. They derieve their nutrition from other sources. Animals do not produce their own food, they depend on plants and other sources for their food. Some animals are herbivores that feeds on plants. Some are carnivores they feeds on flesh. Some can feed on both plants and animals and are called omnivores.

Explanation: Invasive species are living organism that create ecological or economical harm. They either ruin the enviorment or the people living in it when found in large quanitites. Hope this helps!

Final answer:

Invasive species in Australia, such as the cane toad, European rabbit, and red fox, pose significant threats to native ecosystems. Climate change may also increase the risks of 'sleeper' weeds becoming invasive, requiring proactive management and biodiversity protection strategies.

Explanation:

Invasive species in Australia are non-native organisms that disrupt the local ecosystems. An infamous example is the cane toad (Bufo marinus), accidentally introduced to control pests in sugar cane fields, this species now threatens the native Australian fauna due to its toxic skin that poisons predators. Other significant invaders include the European rabbit (Oryctolagus cuniculus), which has caused extensive ecological damage due to overgrazing, and the European red fox (Vulpes vulpes), a predator that has contributed to the decline of ground-nesting birds and small mammals.

Research such as Duursma et al. (2013) indicates that climate change could introduce "sleeper" weeds that may become invasive under future climate scenarios, which could pose new challenges to Australia's biodiversity. Studies by Gallagher et al. (2011, 2015) have explored the invasiveness of species traits and the assisted colonization as a tool for adapting to these changes. With climate change potentially exacerbating the impacts of invasive species, like altering predator-prey dynamics (Doody et al., 2009), early intervention and effective management strategies are crucial.

(D) The special court set up by the executive branch to try suspected terrorists.

Military commissions:On November 13, 2001, President George W. Bush issued a Military Order creating the Guantanamo military commissions to trial some non-citizen terrorist detainees at the Guantanamo Bay jail.Six of the eight military commission convictions to date resulted from plea bargains with the defendants. Most frequently by U.S. federal courts, the appeals process resulted in the complete or partial reversal of several of the eight convictions.Five cases are still pending before the commissions, and two more are on appeal. One of these cases, United States v. Khalid Sheikh Mohammed, et al., involves the prosecution of the inmates who are thought to be most culpable for the September 11 attacks. All five of those cases have yet to be tried in court.

Therefore, the correct answer is (D) the special court set up by the executive branch to try suspected terrorists.

What was a Nazi concentration camp?

Answers

Nazi concentration camps were work camps that were run by Hitlers SS police. These camps were set up to hold prisoners while torturing them or using them for work. These are not the same as extermination camps which were used for the mass killings of Jews.

Most prisoners were anything labeled "undesirables" such as German Communists, Socialists, Social Democrats, Jehovah's Witnesses, homosexuals, and persons accused of 'asocial' or socially 'deviant' behavior by the Germans (criminals), Jews, Soviets, disabled people, and clergymen.

Nazi concentration camps were facilities where individuals were detained by the SS under severe and inhumane conditions, often leading to forced labor or execution. Established initially for political dissidents and groups deemed 'unfit,' they became sites of mass murder and systematic genocide, particularly against Jews, with over 1000 camps built by 1945.

A concentration camp during the Nazi regime was a facility where individuals were detained under harsh conditions without due process. These camps, controlled by the SS, were characterized by unsanitary conditions and inadequate provisions for the prisoners. Initially, camps like Dachau, established on 3/22/33, were used to incarcerate political dissidents and groups deemed undesirable by the Third Reich, including Jews, artists, and intellectuals. As the Second World War progressed, the concentration camps transformed into forced labor and death camps. Prisoners were exploited for labor, often related to war efforts, in factory settings or industries extracting raw materials. This forced labor was conducted under brutal conditions that resulted in high mortality rates. Furthermore, many camps, such as Auschwitz, were equipped with gas chambers to systematically exterminate prisoners, especially Jews.

Nazi Germany built over one thousand concentration camps across occupied territories from 1933 to 1945. The SS's implementation of 'protective custody' allowed for indefinite detention without trial, contributing significantly to a climate of fear that undermined potential resistance within Germany. These camps not only facilitated the Nazi's heinous genocide but also served as a tool for terror within the country itself.

How can the Federal Reserve control money supply? (Select all that apply.)
A- print more money
B- interest rate manipulation
C- open market operations
D- adjust reserve ratios

Answers

Answer:

C. open market operations , B. interest rate manipulation and D. adjust reserve ratios

Explanation:

The Federal Reserve control money supply by buying and selling of government securities.This is called open market operations.Buying of treasury bills from banks and  securities providers it will increase the money supply in the economy. In changing the interest rate, Fed can give banks more reserves by lowering the interest rate it charges on banks allowing them to borrow more. Fed can discourage banks from borrowing more through raising the interest rate. Reserve ratio is a percentage value that banks reserves should show/hold relative to deposits.When the reserve ratio decreases, the bank is going to led more to clients thus increasing the money supply in the economy. Increased reserve ratio will make the banks to led less to cliets thus reducing the money supplting in the economy.

Best of Luck!

Final answer:

The Federal Reserve controls the money supply primarily through interest rate manipulation, open market operations, and adjusting reserve ratios. The Federal Reserve's tools directly influence banks' lending capabilities and consequently affect the amount of money circulating in the economy.

Explanation:

The Federal Reserve can control the money supply through several methods, including B- interest rate manipulation, C- open market operations, and D- adjust reserve ratios. These are the primary tools used to implement U.S. monetary policy. The Federal Reserve does not print money; this is done by the Bureau of Engraving and Printing under the Department of the Treasury.

Open market operations involve buying and selling federal government bonds on the open market to alter bank reserves. When the Fed buys bonds, bank reserves increase, which can lead to more lending and an expanded money supply. Conversely, when the Fed sells bonds, bank reserves decrease, potentially tightening the money supply.

The Fed also manages the money supply through setting the reserve requirements, which dictate how much banks need to hold in reserves compared to their deposits. Changing these requirements can influence the amount of money banks have available for lending.

Lastly, the Fed affects the money supply via interest rate manipulation, such as adjusting the discount rate or the target federal funds rate, which influences the rates at which banks borrow money and thereby impacts their lending practices.

Explanation:

The Democratic Party is the oldest voter-based political party in the world and the oldest existing political party in the United States, tracing its heritage back to the anti-Federalists and the Jeffersonian Democratic-Republican Party of the 1790s.

After the Federalist John Adams was elected president in 1796, the Republican Party served as the country's first opposition party, and in 1798 the Republicans adopted the derisive Democratic-Republican label as their official name.

The political parties that eventually developed in the United States were the first modern political parties in the sense that they drew broader representation from the general electorate than political groups in other nations.
