How do you get the specific gravity of a mineral?
Fill a beaker with water, and weigh it. Weigh a sample of the mineral. That's the mass of the mineral. Put the sample in the beaker and weigh that. The weight of the water-filled beaker plus the weight of the mineral sample will be greater than the weight of the beaker with mineral sample and water. The difference is the weight of the displaced water, in grams. The volume of the mineral sample, in cubic centimeters is equal to the weight of the displaced water, in grams. Calculate the specific gravity of the mineral by dividing the weight of the mineral sample by the volume of the mineral sample. Example: your beaker weighs 40 grams. Filled with water, it's 1040 grams. The sample of mineral weighs 160 grams. The beaker with the sample of mineral and water weighs 1179.7 grams. The mineral, and the beaker with water would have a combined weight of 1200 grams, but the beaker with mineral and water weighs 20.3 grams less than that, so the mineral sample is displacing 20.3 cubic centimeters of water. Given a mass of 160 grams and a volume of 2.03 CC, the specific gravity would be found by dividing 160 by 20.3. It's 7.85. (Which happens to be the specific gravity of some iron.)
Why does limewater disslove in rainwater?
Limewater IS dissolved in water. Limestone dissolves in water because the mineral calcite it comprises of is soluble. This is why limestone dissolves in water.
Mineral dissolves in water this is called?
The mixture when elements that form a mineral dissolve in hot water is called a solution.
When sugar dissolves es in water is the change in entropy positive or negative?
increase
If sugar dissolves in tea is it positive or negative?
Sugar dissolves in water because both water and sugar are polar.
When chalk dust dissolve in water it is called?
When chalk (the mineral) dissolves in water, it's called "limewater".
What is the mineral property defied by Density of the mineral sample divided by the density of water?
Specific gravity.
When HCl is dissolved in water the only positive ion present in the solution is?
When HCl (a strong acid) dissolves in water, the positive ion that forms is the hydronium ion, H3O+.
What happens sodium chloride dissolves in water?
It separates into positive sodium and negative chloride ions.
When rock dissolves into water?
The main agents for chemical weathering are water and weak acids formed in water, such as carbonic acid (H2CO3). These agents dissolve some rocks, loosen mineral grains, form clay mineral, and widen fractures.
