Answer:Step 1: Gather the Needed Materials (coffee Filter, Pencil, Beaker, Water Soluble Pen/marker, Water) Step 2: Cut a Strip of Filter Paper From the Coffee Filter and Using the Marker Draw a Thick Line Near the Bottom of the Filter Paper- About 1/4 Inch From the Bottom. Step 3: Allow the Water to Move Up the Paper for Approx. 5 Minutes and Then Remove the Strip From the Water Step 4: Students Should Identify the Individual Colors in the Chromatogram That Make Up the Markers Unique Mix of Ink. Step 5: Once Students Have Mastered the Technique Its Time to Put Their Skills to the Test in "The Case of the Celebrity Dog-napping" Step 7: Write the Ransom Note on a Piece of Filter Paper in One of the Suspect Inks.
Explanation: Chromatography is the physical separation of a mixture into its individual components. This lesson integrates mixtures, solutions & solubility into an activity where students will identify the solute & the solvent. Because chromatography can be used to separate the components of inks & dyes, students are able to identify the unique "recipe" that makes up the mixture of a specific brand of pen. After the students are taught the ink chromatography technique, the fun can continue with a mini forensic investigation, "The Case of the Celebrity Dog-napping".
just use avogardo's number which show that 1 mole has 6.022×10^23 atoms. so if you have 6.33 x 10^24 atoms of C, just divide that by 6.022x 10^23 and plug it into a calculator.
1.rate of reaction should be indicated by symbols 2.we should indicate physical states by sybloms 3.reversible reaction should be indicated by using double arrows
N<span>etwork of bonded ions is established</span> between two atoms due to transfer of electrons from one atom to the other. therefore, Sodium chloride is formed from a network of bonded ions. hence the right answer is <span>D) salt, NaCl</span>
