What else can I help you with?
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 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
Another name for a key on a map?
The Key, or Legend, or a map gives a list of the symbols used on the map and what they represent. There is a fairly standard set of symbols used for different types of map so that anyone looking at the map can understand what it is being shown. For example, on a weather map a cold front is shown as a black line with semi-circular bumps (in blue if coloured), a warm front is shown as a black line with triangles (in red if coloured) and an occluded front is shown as a black line with alternate semi-circular bumps and triangles.
What materials could have been found in a giant cloud that formed the solar system?
More or less the same materials that are in the Solar System today - except that our Sun must already have converted a significant amount of hydrogen-1 to helium-4 in the meantime. So, the original materials must have been: mainly hydrogen-1, less hydrogen-2 (deuterium) and helium-4, and only fairly small amounts of the so-called "metals", i.e., any heavier elements. Of course, those heavier elements were essential in the formation of the Earth and hence the existence of life in the solar system.
Do wombats have special markings?
No. Wombats have fairly uniform grey-brown coloured fur.
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 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.
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.
What is Fairly soluble?
"Fairly soluble" refers to a substance that dissolves in a solvent to a moderate extent, meaning it has a noticeable but limited solubility. This implies that while some of the substance can dissolve, there is a significant amount that does not, resulting in a mixture that is not completely homogeneous. The term is often used in chemistry to describe the solubility of compounds in solvents like water.
CaCO3 soluble or non soluble in water?
Calcium carbonate (CaCO3) is considered sparingly soluble in water. While a small amount of calcium carbonate can dissolve in water to form calcium and carbonate ions, its solubility is limited and it is often observed as a white precipitate in water.
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.
Can we use hot distilled water to dissolve KMnO4 properly when preparing solution?
Yes, you can, but it isn't necessary because KMnO4 is fairly soluble in room temperature water.
How fast does a B12 injection work?
b12 is water soluble so it should be out of your system fairly quickly.... but I would guage it on the amount of your fatigue. when u get tired its gone.
How long is a baby?
50 to 55 cm (20 to 22 inches) is fairly average. Heavier babies may be up to 70 cm (28 in) in length / height.
What is the difference between water soluble and fat soluble vitamins?
Fat soluble vitamins do not have to be taken everyday because they are stored in your liver, and too much of them can cause health problems. On the other hand, water soluble vitamins are not stored in the body and must be ingested everyday (whether in food or supplement). Still, taking too much of water soluble vitamins isn't healthy either.Water soluble vitamins are not stored in the body to any great degree and must be supplied on a fairly regular basis examples are Vitamins ; C,B1,B6,B12 (the are more)fat soluble vitamins can be stored in the body for longer periods of time and are stored in the bodies tissues most often in fat cells;some examples of fat soluble vitamins are A,E and D (there are more)The difference between them is the water soluble vitamins can be absorbed into your body and be used for energy, the fat soluble ones are turned into fat molecules and stored in your body.
