6. Why can't water be used to dissolve the
caffeine found in coffee and tea?

Answers

Caffeine or supercritical carbon dioxide is a less polar compoundWater is highly polar solvent.So water can't dissolve caffeine much.

Alcohol is used to extract caffeine

Tea's chief component is cellulose, which is not soluble in water. Caffeine is water soluble, but so are tannins and gallic acid, which have been established during the heating process of tea leaves. The latter two components can be converted to insoluble in water calcium salts.

What is solubility?

The maximum amount of a substance that will dissolve in a given amount of solvent at a given temperature is defined as solubility.

Solubility is a property of a specific solute-solvent combination, and the solubilities of different substances vary greatly.

It is one of the critical parameters for achieving the desired drug concentration in systemic circulation for the desired (anticipated) pharmacological response.

Caffeine is more soluble in nonpolar methylene chloride than in water, so it will migrate to the methylene chloride layer (known as the organic layer). Because the organic layer is denser than water, it will be at the bottom.

Thus, water can not be used to dissolve the caffeine found in coffee and tea.

Type your answer here: The purpose of the experiment was to perform and observe the results of a variety of chemical reactions. To become familiar with the observable signs of chemical reactions. To identify the products formed in chemical reactions and predict when a reaction will occur. To write balanced equations for the reactions studied.

Explanation:

sorry i can only tell you the first one

Introduction

What was the purpose of the experiment?

The purpose of this experiment is to create CO2, also known as carbon dioxide, and observe chemical reactions.

How can you identify the gas produced in a chemical reaction without observing the atoms and molecules directly? Explain.

If I look at how the gas would react or its qualities, I can identify the gas without having to observe its atoms directly.

Write a hypothesis based on observations and scientific principles.  

I hypothesize that the mixture produced carbon dioxide, an acidic and colorless gas. In addition to organic materials, such as leaves and dirt, carbon dioxide is also produced when they decay.

Experimental Methods

What tools or materials did you use to collect your data?

To conduct my experiment, I used a glass cup, baking soda, vinegar, paper to record my observations, and a match.

Data and Observations

Record your observations.  

The baking soda and vinegar made bubbles and some steam. When I put the match above the glass, the flame went out.

Conclusions

What conclusions can you draw about the identities of the gases produced in each chemical reaction? Write an evidence-based claim.

The chemical reaction of CO2 caused the flame to go out.

Based on your observations, which equation best models the reaction of vinegar (C2H4O2) and baking soda (NaHCO3)? Explain.

"C" _"2"  "H" _"4"  "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2

"C" _"2"  "H" _"4"  "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"O" _2

"C" _"2"  "H" _"4"  "O" _"2" +"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"H" _2

"C" _"2"  "H" _"4"  "O" _"2" +2"NaHC" "O" _"3" →"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2

The equation that best models the reaction of vinegar is A

Because "C" _"2"  "H" _"4"  "O" _"2"  is the acid vinegar

"NaHC" "O" _"3"   is the baking soda  

"Na" "C" _2 H_3 "O" _"2" + "H" _2 "O"+"C" "O" _2 is the product or the reaction.

Answers

Answer:1).A nonrenewable resource is a natural substance that is not replenished with the speed at which it is consumed. It is a finite resource.

2)Rocks are made of minerals, like quartz, calcite, feldspars, and micas. Most rocks are made from more than one mineral, but there are quite a few kinds that are made from only one mineral. Minerals are not rocks, rocks are made of minerals.

3)Coal is a very useful rock that formed over millions of years from the ... No, coal is not a mineral because coal is made of dead plants.

4)The relatively cheap cost of fossil fuels is a major positive aspect. They are in abundant supply, which makes them inexpensive to drill or mine for. In particular, coal is one of the most widely available fossil fuels.

5)High initial costs for material and installation and long ROI (however, with the reduction in the cost of solar over the last 10 years, solar is becoming more cost feasible every day) Needs lots of space as efficiency is not 100% yet.

its attention during the early days of the civil rights movement on doing which of the following?

Answers

Answer:

Although the Declaration of Independence stated that "All men are created equal," due to the institution of slavery, this statement was not to be grounded in law in the United States until after the Civil War (and, arguably, not completely fulfilled for many years thereafter). In 1865, the Thirteenth Amendment was ratified and finally put an end to slavery. Moreover, the Fourteenth Amendment (1868) strengthened the legal rights of newly freed slaves by stating, among other things, that no state shall deprive anyone of either "due process of law" or of the "equal protection of the law." Finally, the Fifteenth Amendment (1870) further strengthened the legal rights of newly freed slaves by prohibiting states from denying anyone the right to vote due to race.

Despite these Amendments, African Americans were often treated differently than whites in many parts of the country, especially in the South. In fact, many state legislatures enacted laws that led to the legally mandated segregation of the races. In other words, the laws of many states decreed that blacks and whites could not use the same public facilities, ride the same buses, attend the same schools, etc. These laws came to be known as Jim Crow laws. Although  many people felt that these laws were unjust, it was not until the 1890s that they were directly challenged in court. In 1892, an African-American man named Homer Plessy refused to give up his seat to a white man on a train in New Orleans, as he was required to do by Louisiana state law. For this action he was arrested. Plessy, contending that the Louisiana law separating blacks from whites on trains violated the "equal protection clause" of the Fourteenth Amendment to the U.S. Constitution, decided to fight his arrest in court. By 1896, his case had made it all the way to the United States Supreme Court. By a vote of 8-1, the Supreme Court ruled against Plessy. In the case of Plessy v. Ferguson, Justice Henry Billings Brown, writing the majority opinion, stated that:
