C. Nitric acid and perchloric acid are labelled with the pictogram below. Would you store the glacial acetic acid with these acids? Explain your decision. Asid nitrat dan asid perklorat dilabel dengan piktogram di bawah. Adakah anda akan menyimpan asid asetik glasial dengan asid-asid tersebut? Jelaskan keputusan anda. * d. Explain the probability of forming a combustible mixture if a 1 L of glacial acetic acid is used in a 3 x 4 x 2.5 m room? The specific gravity is 1.049, relative to water and the vapor density is 2.1, relative to air. The Lower Explosive Limit (LEL) is 4 % by volume of air and the incomplete mixing factor of 5.

How do you separate sodium hydroxide from the crude mixture?

Correct answers are given!!! Please just show me how to get them.

True or false 1.At melting point the equilibria exist between liquid and solid phase. 2.The mixture of solids which had eutectic point 108 C melted below 108 C. 3.The highest melting point temperature for the impure sample is higher than the pure sample. 4.Bronsted-Lawry acid base reaction can occur only in organic phase. 5.Weak acids are not ionized completely.

Need help with 6. Unsure why got rejected as this is a pre lab question and is not graded. Our lab itself is what is graded. We then follow it by post questions.

. What reaction occurs when sodium hydroxide is added to the stearic acid in cyclohexane and water?How does this change the solubility of cyclohexane in water? Does HCl reverse this reaction and if sowhy? Does sodium chloride have the same type of behavior as stearic acid or is it different? Explainwhy these two solutes are the same or different. (do not copy an answer from chegg, please)

Calculate the moles of OH- present in the sample aliquots for each trial

Part A The chemical 5-amino-2,3-dihydro-1,4-phthalazinedione, better known as luminol, is used by forensic scientists in analyzing crime scenes for the presence of washed-away blood. Luminol is so sensitive that it can detect blood that has been diluted 10,000 times. A basic solution of luminol is often sprayed onto surfaces that are suspected of containing minute amounts of blood. The forensic technician at a crime scene has just prepared a luminol stock solution by adding 15.0 g of luminol into a total volume of 75.0 mL of H2O. What is the molarity of the stock solution of luminol? Express your answer with the appropriate units. Luminol has a molecular weight of 177 g/mol. • View Available Hint(s) HẢ molarity of luminol solution = Value Units Submit Part B Before investigating the scene, the technician must dilute the luminol solution to a concentration of 6.00x10-2 M. The diluted solution is then placed in a spray bottle for application on the desired surfaces. How many moles of…
