What will be the probable effect if you kept the crucible completely covered during the entire heating and cooling processes? Would your calculated percent water in the hydrate be high, low, or unaffected? Explain. 3. If 2.752 g sample of Ca(NO:); XH;O is heated to constant mass, the residue weighs 1.941 g. Determine the value of x and the formula of the hydrate.

Procedure it attached below, but question is in the screenshot.   Part A: Solution Preparation Work in pairs.  Wear safety goggles and an apron.  Connect the temperature probe to Channel 1 of the LabQuest2. The vertical axis has temperature scaled from 0 to 50°C.  To set the horizontal axis (time) to 0 to 1000 seconds, go to the  menu and change the Duration to 1000 seconds. Wear gloves for this step only, 2.5 M acid can cause burns.  When diluting concentrated acid, pour acid into water, slowly with stirring; never the reverse. HAVE A DILUTION PLAN BEFORE COMING TO LAB.  (Use the concentration values and volume below in the dilution equation to find the volume of stock solution needed to create the dilute solution.)  Using only volumetric glassware, prepare 250.00 mL of approximately 1.0 M HCl solution from the stock HCl solution in the hood (approximately 2.5 M).  The exact concentration for the stock solution must be recorded from the bottle’s label and the exact concentration for…

my unknown # is 5.

. Be sure to understand what the dilutionfactor is for each sample (dilution factor = the number used to determine the actualconcentration of the stock UK after the diluted samples are analyzed) ?

TRUE OR FALSE _ 1. To dispense chemicals, read the label at least twice before removing any chemical from the reagent bottle. __________ 2. When heating a liquid in a test tube, the test tube should be more than two- thirds full, moved continuously in and out of the cool flame at a 45o angle, mostly near the top of the liquid. __________ 3. The volume of a liquid should be read at the bottom of the meniscus. __________ 4. A litmus paper test for the acidity or basicity of a solution is done by dipping a stirring rod into the solution and using this to wet the litmus paper. __________ 5. Water or glycerol should be applied to the glass tubing and the hole in the rubber stopper before inserting the glass tubing.

PROCEDURE 1. On a clean, dry, and flat surface, place a parchment paper, or any non-porous flat sheet. 2. Obtain your medicine tablet. Take note of its mass. [Note: Since this is home experiment and that you might not have a weighing scale at home, assume that given mass of the tablet is pure, with any excipient/(s). For example, a 500 mg ascorbic acid will have a mass of 500 mg as indicated.] 3. Pulverize the tablet into fine powder and trransfer it in a clean and dry vessel or bottle. 5. Add the necessary amount of distilled water to make the desired concentration of stock solution assigned to your group. [Note: Assume that the volume of the solute is negligible compared to the volume of the solution.]  Concentration of STOCK SOLUTION, M Concentration of DILUTED SOLUTION, M 0.8 M 0.16 M 6. Make sure to place the computations used in the data sheet. PLEASE FILL IN THE MISSING TABLES IN THE DATA SHEET. THANK YOU!

Question 7/19 > NEXT A BOOKMARK Almonds are edible seeds that grow on trees. Wild almonds typically have a bitter taste caused by a chemical in the almond. If an organism eats wild almonds, a chemical reaction occurs that releases the bitter taste. However, a genetic mutation in the almond tree can occur that prevents wild almonds from producing the bitter taste. Which statement describes how this type of mutation could affect these wild almond trees? 7 A This mutation could increase the population of wild almond trees. B This mutation could increase the life span of wild almond trees. (c) This mutation could decrease the rate of the production for wild almond tree P Type here to search DELL
