and richterite, which form a solid solution series and are not regulated under Federal Regulations (EPA 1987d; OSHA 1998a, 1998b). Asbestiform varieties of these amphiboles were found in vermiculite ore in Libby Montana (Wylie and Verkouteren 2000). Table 4-1 lists common synonyms and other pertinent
The procedure is done in 3 steps 1) Preparation of a standard Ca2+ solution, 2) Standardi-zation of EDTA with the standard calcium solution and, 3) Analysis of an unknown Ca2+ sample with the standardized EDTA solution. 1. Standard calcium solution. 0.405 g of CaCO 3 is dissolved in HCl and diluted to a volume of 250.00 mL. What is the
3.56 to 3.76. Only common mineral with significant hardness difference in two directions. Two directions: Perfect in one direction (prismatic), poor in another direction (prismatic) 3 to 4. Colorless to White or Grey, may be tinted other colors. Vitreous to sub-vitreous, silky when fibrous.
1. A 10.00 mL volume of unknown liquid was added to a stoppered Erlenmeyer flask which weighed 48.217 g. If the weight of the unknown liquid plus the stoppered Erlenmeyer flask was 57.056g, calculate the density of the unknown to the correct number of significant figures.? This is …
Oct 26, 2000 OBSERVE: A source of confusion is the switch from mineral names to rock names.Clay is a mineral that forms from the weathering of feldspars such as orthoclase.Clay is extremely fine grained; it is the mud on your shoes, or the mud (suspended clay) in a river or pond. When clay is deposited it becomes the rock shale Calcite (CaCO 3) is a mineral with rhombohedral cleavage that reacts with ...
A 307-g sample of an unknown mineral was heated to 98.7 C and placed into a calorimeter containing 72.4 g of water at 23.6 C. The heat capacity of the calorimeter was 15.7 J/ C. The final temperature in the calorimeter was 32.4 C. What is the specific heat capacity of the mineral? a. 0.124 J/g C b. 0.131 J/g C c. 0.138 J/g C
1. While transferring a solution from a flask to a beaker, the solution accidentally spills down the front of the lab bench. _____. 2. While checking on a stirring solution, the solution splashes up towards your face. _____. 3. While picking up a buret, an unknown solution left by a previous solution drips onto your hand. _____. 4.
1 ml of the previously diluted solution is taken and volume is made up to a final volume of 2 ml by the addition of distilled water. how to calculate the concentration of the diluted solutions if they unknown ? First: find the D.F: Dilution factor (D.F) = final volume / aliquot volume = 2/1 = 2 Second: divide the previous solution concentration
Very little is known about how mineral oil hydraulic fluids and polyalphaolefin hydraulic fluids will affect your health. There are reports of health effects in people exposed to these classes of hydraulic fluids. After drinking mineral oil hydraulic fluid, a child developed pneumonia and bleeding in the intestines and then died.
Each higher-numbered (harder) mineral will scratch any mineral with a lower number (softer). A rough measure of mineral hardness can be made by assembling a kit of handy objects (table 6). A fingernail has a hardness ranging from 2 to 2.5, a penny is a little harder than 3, window glass ranges from 5.5 to approximately 6 in hardness, and a ...
