What is the formula for silver phospate?
The formula for silver phosphate is Ag3(PO4).
How many electrons are in Ag 3?
There are a total of 3 silver atoms in Ag3. Since each silver atom has 47 electrons, the total number of electrons in Ag3 would be 3 * 47 = 141 electrons.
What is the oxidation number of silver 1?
+1 . The oxidation number of an ion is always equal to the charge. The silver ion is Ag+ in compounds such as silver chloride. There is also an Ag3+ in compounds such as AgO, which contains Ag+ and Ag3+ in 1:1 proportions, so contains silver with +1 and +3 oxidation numbers and is called silver(I,III) oxide
What is the value of an US 1845 silver dollar?
Retail prices range from $275 to $600 depending on condition.A circulated Liberty Seated Dollar dated 1845 retails at $275.00-$410.00 for average coins that show heavy wear, better coins are $475.00-$810.00. A mint state coin is $8,700.00
What is different between ag4 and ag3 batteries?
AG4 and AG3 batteries differ primarily in size and capacity. The AG4 battery, also known as LR626, has a diameter of 6.8 mm and a height of 2.6 mm, while the AG3 battery, or LR41, measures 7.9 mm in diameter and 5.4 mm in height. Consequently, the AG4 typically has a lower capacity compared to the AG3, which can affect their applications in devices. They are not interchangeable due to these size and voltage differences.

I found a 1916 Barber Dime minted in San Francisco. Can anyone tell me the approx. value Condition appears poor.?
A 1916-S Barber Dime in about good condition (AG3) is worth: $2.50.
What is the total ionic equation for silver nitrate plus sodium sulfate?
3 AgNO3 + Na3 PO4-->Ag3 PO4 + 3 NaNO3 You need three silver nitrate molecules:one sodium phosphat molecule to complete the reaction. Just swap the ions.
How much are copper pennies worth?
There were about one billion coins produced this year. The mint went back to brass coins and used spent shells from the navy and army to produce Lincoln cents in 1944. So the coins are also called "shellcase bronze". A 1944 Lincoln cent in AG3 to MS67 Red is equal .04 cents to about $115.00. If you have a D/S Mintmark the value runs from $35.00 to Thousands.

What is the chemical property of silver?
Silver is in group 11, it has an electronic configuration of [Kr]4d105s1Silver metal is chemically relatively inert hence its use as a coinage metal. It is sensitive to sulfur compounds forming a black tarnish of silver sulfide Ag2SSilver(I)It has some similarities to the alkali metals as it loses one electron to form the Ag+ ion. One difference is that the Ag+ ion is small and therefore polarising (Fajans rules) and the salts such as AgCl are more covalent in character than their alkali metal analogues. AgCl unlike NaCl is quite insoluble in water. Precipitation of AgCl and weighing the precipitate ("gravimetric" analysis) is a method of determining chloride. AgBr is particularly sensitive to light, producing Ag metal and was used in photographic film. The silver mirror test for for aldehydes which reduce the Ag+ ion to Ag metal depositing it on the side of the vessel shows how easily Ag+ is reduced. (Note ketones do not reduce Ag+)The oxide Ag2O is known readily forming when precipitated AgOH is allowed to dry.Many compounds of silver(I) are best described as covalent, for example silver cyanide, silver sulfate where the coordination number of silver is 2 with linear bonding. Silver (I) forms many complexes with nitrogen ligands for example AgCl dissolves in liquid ammonia to form [Ag(NH3)2]+Silver(II)Ag can form other compounds where it loses a further one or two electrons (from the 4d shell). The Ag2+ ion is produced in aqueous solution by oxidation of AgI compounds with ozone. These ions are not stable, unlike copper where Cu2+ is well known. e.g. copper sulfate. AgF2 is known but AgCl2, AgBr2 are not. The oxide which appears to contain AgII is in fact a mixed valence oxide silver(I, III) oxideSilver(III)Some silver(III) compounds are known, AgF3 which is red. This oxidises xenon the inert gas to form XeF2. Then [Ag(OH)4]- ion containing Ag3+ is produced electrolytically in strong (12M) KOH solution. It gives the solution a yellow color which fades slowly, half life 100 mins or so.The wikipedia article on silver is not very good imho and most text books are weak on summarising trends.
What chemical reactions take place in photography?
Several different chemical processes have been used in photography. Some of the earliest used silver salts that darkened on exposure to light. These salts were coated on metal plates and then had an image projected on them through a lens. Daguerreotypes used silvered copper plates that were exposed to iodine and bromine vapors to convert the surface silver to silver iodide and/or silver bromide. Once the image was created by exposure to light, the image was made permanent by exposing the plate to mercury vapor which probably formed an amalgam with the sliver in the lighter areas that stuck to the plates. After development, the plates were washed with a hot salt solution which removed the silver from the darker areas where the mercury had interacted less with the silver. More modern black and white photography uses grains of silver halides suspended in a gel. The chemistry of exposure is typically something like: Ag+Br- (crystal) + hv (radiation) --> Ag+ + Br + e- The silver ion can then combine with the electron to produce a silver atom. Ag+ + e- --> Ag0 Association within the grains produces species such as Ag2+, Ag20, Ag3+, Ag30, Ag4+, and Ag40. The grains containing the free silver in the form of Ag4º are readily reduced by chemicals referred to as "developers" forming relatively large amounts of free silver; the deposit of free silver produces a dark area in that section of the film. The developer under the same conditions does not significantly affect the unexposed grains. Silver halide developers include: p-Dihydroxybenze, Monomethylparaminophenol,1,2,3 Trihydroxybenzene, p-Aminophenol, Diamonophenol, and 1-Phenyl-3-pyrazolidone. Once the exposed image has been developed to the desired degree, it is necessary to halt the chemical process quickly to prevent over-development and the production of fog. The solution used to that end is referred to as the "stop" bath. Since developers function a relatively high pH's, the typical stop bath is simply a solution of acetic or some other weak acid. The action of the acid is so rapid it usually requires only seconds for the process to be effectively halted. The silver halides are only slightly soluble in water; therefore, to remove the material remaining after development it is necessary to convert it to soluble complexes which can he removed by washing. Sodium thiosulfate, commonly termed "hypo," has been used for this purpose since 1839. The reactions in fixing can be written as follows: AgBr + S2O3-2 --> AgS2O3- + Br- (adsorption complex) which is followed by AgS2O3- + S2O3-2 --> Ag(S203)2-3 (desorbed) and by Ag(S203)2-3 <--> AgS2O3- + S2O3 -2; AgS2O3 <--> Ag+ + S2O3-2 Recovery of the dissolved silver complexes is rather important in order to make this process affordable, so the used "hypo" is saved for later processing.
What does ms 67 mean in coin collecting?
Coins are graded according to their condition. The grades are expressed in letters and numbers from 1 to 70.. For example, a very worn coin may be graded as AG3 which would mean "almost good 3", the number indicates the coin is in poor condition and is low on the scale from 1 to 70. G4 would mean "good" and the 4 indicates the coin is in a little better condition than the AG3. You will find terms like "F12" meaning the coin is grades "fine 12", or you may see EF40 meaning the coin is "extra fine 40". A higher number indicates a better grade coin. . All coins that have never gone from hand to hand in daily business, will have the letters "MS" and then a number from 60 to 70. "MS" means "mint state" and refers to the condition of a new coin while it was at the mint. These coins that are never used after they leave the mint are called "uncirculated" [like new]. In your question you asked about MS67. This means the coin is in "mint state" [like new] and the 67 indicates it is of very high quality and nearing perfection.
