What characteristics do atoms of mangnaese-55 iron-56 and nickel-58 have in common?
They are all transition elements, so all are fairly unreactive, form coloured compounds and are hard and strong elements, they can be used to make alloys.
How does gasoline remove tar spots?
Tar and gasoline are both hydrocarbons, and so tar is fairly soluble in gasoline, which means that it will dissolve in it, and you can then wipe it off. There are safer cleaning products to use than gasoline however, which is extremely flammable and dangerous to work with.
How do water soluble vitamins differ from fat-soluble vitamins?
Solubility refers to the ability of a substance to dissolve in a particular solvent. Most vitamins are soluble in either water or fats. fats soluble vitamins cannot be dissolved in water and require mixture with oils or fats in order to be used by the body.
Are esters soluble in alcohols?
"The small esters are fairly soluble in water but solubility falls with chain length.The reason for the solubility is that although esters can't hydrogen bond with themselves, they can hydrogen bond with water molecules. One of the slightly positive hydrogen atoms in a water molecule can be sufficiently attracted to one of the lone pairs on one of the oxygen atoms in an ester for a hydrogen bond to be formed." http://www.chemguide.co.uk/organicprops/esters/background.html
What is thought to be the physical mechanism that was responsible for the present mix of chemical elements in the universe?
1) Hydrogen and some helium and a fairly small amount of lithium were formed very shortly after the start of the Universe, when matter cooled down enough for quarks to join into nucleons, and for some nucleons to join into heavier elements. There wasn't enough time to form any of the heavier elements.2) The heavier elements - the so-called metals - were formed inside of stars, by nuclear fusion. In some cases, significant amounts of this matter went back into space, in supernova explosions.For additional information, I suggest searching Wikipedia or Google for the following topics:NucleosynthesisSupernovaMetallicityNuclear fusion
CaCO3 soluble or non soluble in water?
It's not soluble in water, although it does produce a precipitate.
Do wombats have special markings?
No. Wombats have fairly uniform grey-brown coloured fur.
Is a hilo monster poisonous?
If you mean Gila monster, the answer is yes--its venom is poisonous. Because the lizard is fairly slow and stays out of the way of humans, though, encounters with them are fairly rare. Also, their bite has to be firm and deep to inject the venom, so fatalities are almost unheard of.
Why is that benzaldehyde is not soluble in water?
It is soluble in water 0.6 g/100 ml (20 °C). It has fairly low solublity because its a non-polar hydrocarbon with a low percentage of oxygen in the molecule.
Are poinsettias poisonous to deer?
Not really, no, unless your rabbit munched its way through a LOT of plants. Poinsettias being poisonous to pets and kids is a fairly old urban myth.
Why alcohol used instead of mercury in modern thermometers?
Because mercury is toxic, poisonous while alcohol is fairly harmless.
Why does copper sulfate and hydrochloric acid produce no precipitate?
All chlorides are fairly soluble, as are copper compounds. Sulfate ions are also relatively soluble as well, so there is nothing to precipitate (unless you cool the solution down a bit).
Are orange spiders poisonous?
No. While an orange spider might have a fairly painful bite, it's bite is not considered to be venomous or poisonous. Some shockingly common spiders with dangerous and poisonous bites are black widows (known by their reddish hourglass design on their back) or brown recluse spiders.
Is silver iodide harmful to humans?
silver isn't unless you get it in your bloodstream. iodine is fairly poisonous so i would say it is harmful.
What are the solubility of zirconium salts in water?
Zirconium fluoride (ZrF4) is nearly insoluble, but Zirconium sulfate (Zr(SO4)2.4H2O) is fairly soluble.
What is Mechanical Chisel?
A mechanical chisel is a heavy, rounded steel chisel with a fairly blunt point. It often has a heavier end for hitting it with a hammer.
Why potassium carbonate cannot be prepared by solvay process?
It is because unlike sodium carbonate potassium carbonate is fairly soluble in water and it does not forms precipitate.
