All of the following chemical laboratory practices are correct except A We must avoid weighing corrosive substances in an analytical balance. B We should always weigh hygroscopic substances using a weighing bottle We should always wait for the substance (to be weighed) to cool down first to room temperature before weighing D We should always prepare the stock solution from the working solution

1 . WHAT ARE THE EQUATIONS FOR THE REACTIONS IN THE EXPERIMENT BELOW A. Test for Carbon and Hydrogena. Grind or cut paper, dried leaves, wood and cloth into small pieces and mix well with 1.5 grams of cupric oxide.b. Transfer the mixture to a dry test tube. Cover with a cork fitted with a glass tubing. Attach rubber tubing to the exposed end of the glass tubing. This is your first test tube.c. Clamp the first test tube on an iron stand in an inclined position and try to distribute the contents by gently tapping itd. Fill another test tube ¾ full of clear lime water. This is your second test tube.e. Immerse the end of the rubber tubing from the first test tube to the second test tube. f. Heat the test tube by holding the Bunsen burner in your hand starting from the middle of the tube going down to the closed end, distributing the heat throughout its contents.g. Stop heating when a significant change in the lime water is observed. No need to answer the items below this. They are just…
Define the following constants and explain how these constants aid in the determination of samples’ quality and identity. a. Peroxide value b. Anisidine value c. Total oxidation value
how do you determine the relative reactivities of metals
When mixing sodium chlorate solution (volume 1.0L, density 1.1614 g/ml, mass fraction 22%) with hydrochloric acid( 2L, density 1.0980 g/ml, mass fraction 20%) an antiseptic substance was released. Write and balance the Mentioned reaction and name this anticipatic substance.
Gold can be determined in solutions containing high concentrations of diverse ions by ICP. Aliquots of 50.0 mL of the sample solution were transferred to each of four 100.0 mL volumetric flasks. A solution was prepared containing 10.0 mg/L Au in 20% H2SO4, and quantities of this solutions were added to the sample solution to give 0, 2.5, 5 and 10 mg/L added Au in each of the flask. The solutions were made up to a total volume of 100.0 mL, mixed and analyzed by ICP. The resulting data are presented in the following table: Added Au (mg/L) Emission Intensity (Counts) 0.0 12568 2.5 19324 5.0 26622 10.0 40021 a) Attach an excel graph for the determination showing the X intercept. b) Calculate the concentration of gold in the sample, report with its uncertainty. c) The known concentration of gold in the sample is 8.51 mg/L. Test the hypothesis that your result is equal to this value at the 95% confidence level. l
