Describe how calcium and fluorine bond together to form calcium fluoride. The electron arrangement of each atom is shown.

Answers

Answer:

Detail is given below.

Explanation:

Calcium is alkaline earth metal. It has two valance electron. Thus calcium needs six more electron to complete the octet. Thus, its very easy for calcium to remove its two electron and get complete octet.

Electronic configuration of Ca:

Ca₂₀ = [Ar] 4s²

While,

Fluorine is halogen. It has seven valance electrons. It needed only one electron to complete the octet. When it combine with calcium , calcium loses two electrons thus two atom of fluorine combine with one atom of fluorine and stable compound calcium fluoride is formed.

Electronic configuration of F:

F₉  = [He] 2s² 2p⁵

Chemical equation:

Ca  + F₂     →     CaF₂

How do I put Chlorofluorocarbons in a sentence?

Answers

Answer: Here are some examples

Explanation:

1. In the southern spring, ozone is destroyed above Antarctica, mainly by manufactured compounds called chlorofluorocarbons (CFCs )

2. It is now generally accepted that the loss of stratospheric ozone is caused by chemical reactions initiated by chlorofluorocarbons.

3. Your refrigerator and other home appliances emit Chlorofluorocarbons, or CFCs, as do aerosol spray cans.

Hope this hlps!

Explanation:

To be able to put the chemical term chlorofluorocarbons in a sentence, you must first understand what the chemical species denotes.

We know chlorofluorocarbons are a group of compounds that consists of atoms of chlorine, flourine, and carbon.

Now, here are some sample sentences;

Chlorofluorocarbons are one of the leading causes of ozone depletion in the atmosphere. Most national governments are putting measures in place to check the use of chlorofluorocarbons in industrial manufacturing.If we can innovate a substitute for chlorofluorocarbons, the environment would be safer.

3. In an exercise to teach students how to use and analytical balance, the instructor
gives a student a quarter which has been pre-weighed as 5.6026 g. The weight that the
student obtains for the same quarter is 5.6013 g. What is the percent error in the
students reading?

Answers

Answer:

The percent error is 0.023%.

Explanation:

Pre-weighed of a quarter is 5.6026 g.

The weight that the  student obtains for the same quarter is 5.6013 g.

We need to find the percent error in the students reading. It is given by the formula as follows :

[tex]\%=\dfrac{|\text{original value-calculated value}|}{\text{original value}}\times 100[/tex]

Putting all the values, we get :

[tex]\%=\dfrac{5.6026 -5.6013 }{5.6026 }\times 100\\\\\%=0.023\%[/tex]

So, the percent error is 0.023%.

Boyd takes additional measurements of the mass of product formed in a reaction. He uses a balance that has smaller graduations than the first balance he used.
What is Boyd most likely trying to change?

Options:
He is trying to increase his accuracy but not his precision.
He is trying to increase his precision but not his accuracy.
He is trying to decrease his precision and increase his accuracy.
He is trying to increase his precision and decrease his accuracy.

Answers

Answer:

The correct option is A: "He is trying to increase his accuracy but not his precision"

Explanation:

Accuracy of measurement is when the value of the measurement is close to the actual value of that measurement while precision is when the experiment is repeated using the same instrument but obtaining different values.

When Boyd changed the weighing balance in his experiment to a smaller one, the smaller weighing balance has better accuracy (smaller graduations) than the initially used one because the smaller weighing balance will provide a value close to the actual value of the mass of the product. If he had, however, repeated the experiment without changing the weighing balance, he would have sought to increase his precision.

From the description above, it can be said that Boyd was trying to increase his accuracy but not his precision

The correct option is A: "He is trying to increase his accuracy but not his precision"

What are alkali metals

Answers

Answer:

Alkali metals are highly reactive elements that appear to be silver and they are found in group 1 of the periodic table.  It consists of lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).  As you go further down the group, the more reactive they are.  Those elements all react to water and air, so they must be kept in oil to preserve their state.  

Alkali metals are any of the elements lithium, sodium, potassium, rubidium, cuisine, and francium, occupying Group 1A (1) of the periodic table. They are very reactive, electropositive, monovalent metals forming strongly alkaline hydroxides.

You are about to take a short trip. However, you will not be traveling by car or bus; instead you will be traveling up in a hot air balloon. You know that hot air balloons, like the ones pictured, are able to rise when the air contained in them is heated. Why does the balloon rise? What is happening at the molecular level to make the balloon rise?

Answers

Answer:

Hot air rises. Heated air molecules “spread out” or expand and bounce around, and the space becomes less dense than the surrounding space. Increasing the air temperature inside the balloon envelope makes it less dense than the air, thus making it “lighter than air”.

How do I solve both of the scenarios Lesson4Words to KnowUnderstanding the following words will help you read this lesson:TERMS & NAMESprimary sourcesecondary sourceoral historyHow HistoriansStudy the PastBuild on What You Know You may know where your parents or ancestors came from and some of the stories about them. Relatives and their stories help people understand their family history. Now learn what historians use to help them understand the past.Understanding the PastESSENTIAL QUESTION What questions do historians ask to help them understand the past?People investigate their family history to find out about their ancestors. In the process, however, they also find out about themselves. We study world history for the same reasons.Why Study History? What has already happened to a person, a family, or asociety affects what will occur today and in the future. But history is much more than simply recounting and studying past events. Examining a historical event also involves studying a societys culture, religion, politics, and economics.When historians examine past events, they try to find patterns. They look for causes and effects that explain how and why events happened. They also try to understand why some ideas and traditions last and why others die out. Just as important, historians attempt to see the past through the eyes of the people who lived it. By doing so, historians gain greater insight into human nature and answer important historical questions.Asking Historical Questions As historians study the past, they ask themselves questions like those below. These questions help historians compare different societies and draw conclusions about the past. How have groups or societies interacted, and what have been the results? How have leaders governed societies? How have belief systems developed and changed? How have societies dealt with differences among their people? How have societies tried to protect peoples security? How are societies similar and different?Why do we study history?The Historians ToolsESSENTIAL QUESTION What methods do historians use to help them answer questions about what happened in the past? When you hang up a picture, you use a hammer to pound in the nail. Historians also use tools to do their job. These tools include primary sources, secondary sources, and oral history.Primary Sources A primary source is something written or created by a person who witnessed a historical event. You will learn about an ancient primary source on the next page. Primary sources include letters, diaries, eyewitness articles, videotapes, speeches, and photographs. Artifacts, such as the human-made tools, are also primary sources.loading...How Knowledge of the Past ChangesESSENTIAL QUESTION What steps do historians take as they answer historical questions?Detectives use fingerprints and other evidence to solve crimes. Historians act as detectives too. They use evidence from primary, secondary, and oral sources.Fact or Fiction? Historical evidence isnt always as simple as a bloodstain at a crimescene. Historians sometimes have more information than they can use when they try to answer a question. They must sort through all of the information and choose whats most important and most trustworthy as evidence. In addition, sometimes what historians thought was true turns out to be false. For instance, one historian proved that the so-called mummyscurse was false. According to legend, the curse would kill anyone who entered the tomb of an ancient Egyptian ruler. Many people believed the curse had caused the death of English archaeologist Lord Carnarvon. He died suddenly in 1923, shortly after entering the tombof ancient Egyptian ruler King Tut. People believe that the other archaeologists who had entered the tomb between 1923 and 1926 would also die as a result of the curse. However, a historian later examined the archaeologists death records. Their average age at death was70 years. The evidence did not support the existence of the mummys curse.Drawing Conclusions The mummys curse was easy to disprove. But not all historical questions are so easily answered. Sometimes different historians arrive at different conclusions based on the same facts.Answer the following questions2. What is the difference between primary and secondary sources?
