Cyclopentane is converted into Ctclopentyl Cyanaide in following two steps,

Step 1:
           Cyclopentane is reacted with Chlorine in the presence of sunlight. A Free Radical Substitution Reaction results in the formation of Chlorocyclopentane.

Step 2:
           In second step, Chlorocyclopentane is reacted with Potassium Cyanide which undergoes Nucleophilic Substitution Reaction resulting in the formation of Cyclopentyl Cyanide as shown below,

Reika [66]

Answer:

False.

Explanation:

(5 kilometers / 30 minutes), you could then say that in 60 minutes (one hour) you would be traveling at (10 kilometers / 60 minutes)...

Therefore, it is unlikely that you would be traveling at (6 kilometers / hour), so the answer should be... False.

Rosa eats peanut butter sandwich for lunch. Peanut butter contains a lot of proteins, and bread is mostly starch. Rosa plan to g
Gemiola [76]

Answer:

Explanation:

This question comprises a couple of questions that are interwoven. However, the description below should suffice.

The part of the food she needs to go for the run is bread (starch) while the component of the air she requires is oxygen. This is because starch are polymers that are made of glucose monomers which are known sources of energy for the body. Air contains nitrogen, oxygen, carbon dioxide and rare gases; the oxygen from air here is necessary for many metabolic activities in the body during the race.

Her respiratory and her digestive system work together to provide her with the molecules (mainly oxygen and glucose) that she needs in her cells. The digestion of starch is a multienzyme process that is summarized as follows. The digestion of the starch (bread) begins in the mouth. The bread is acted upon by the enzyme amylase which is present in the saliva. The enzyme breaks down this starch into small glucose chains and then to dextrins and maltose (which is a disaccharide). The disaccharide is then broken down into glucose. Only a small fraction of the starch is broken down to glucose in the mouth. The broken and unbroken food substance is then taken to the stomach where little activity occur because of the acidic condition but the process continues/accelerates in the small intestine until alot of glucose is produced from the food (bread). The oxygen taken in through the respiratory system is then transported through the circulatory system to various parts of the body. The glucose molecules produced by the breakdown of starch is also diffuses into blood stream and taken up by various cells in the body.

The cells in her body convert these glucose to energy (ATP) through the process known as glycolysis (breakdown of glucose). This energy is what is released from her cells and then used to run.

Empirical formula of at least four binary ionic zn2+,pb4+,br-,s2-
Tasya [4]

Four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

<h3>What are binary ionic compounds?</h3>

Binary ionic compounds are those compounds that contain only two elements. The ionic compounds are those compounds that contain ions. The compounds are able to dissolve in water and they have high melting and boiling points.

Now, four binary ionic compounds that could be formed from each of these ions are;

  • Zn^2+ - ZnCl2, ZnI2, ZnBr2, ZnF2
  • Pb^4+ - PbF4, PbCl4, PbBr4, PbI4
  • Br^- - MgBr2, NaBr, CaBr2, KBr
  • S^2- - CaS, MgS, Na2S, K2S

The prefix mili-means a thousand
OLEGan [10]
<h2>Answer:</h2>

<em>Given data:</em>

1 kilogram = 1,000 grams

how many kilograms is 1,216 grams?

<em>Solution:</em>

1000 grams = 1 kilogram

1 gram = 1/1000 kilograms

1216 grams = 1/1000 * 1216 = 1.216 kilograms.

                                                    <em> Hence 1216 grams =  1.216 kilograms.</em>
