What color is cr3 plus?
CR3+ typically refers to chromium(III) ions which are green in color.
Will Cr3 plus have a noble gas configuration?
Yes, Cr3+ will have a noble gas configuration. It will have the electron configuration of argon (Ar) due to the loss of three electrons from the chromium atom.
What species is reduced in the reaction Fe plus AgNo3 plus Fe(No3)3 plus Ag?
Ag+
Which element has been reduced in the redox reaction AgNO3 plus Na NaNO3 plus Ag?
Silver (Ag)
Is Cr3 plus plus e-Cr2 plus reduced or oxidised?
Cr3+ is reduced to Cr2+ because it gains an electron, which leads to a decrease in oxidation state. Conversely, the electron is being donated, so the species donating the electron is oxidized.
What color is cr3 plus?
CR3+ typically refers to chromium(III) ions which are green in color.
The ions Cr3 plus and O2- combine to form the ionic compound chromium oxide. In what proportions do these ions combine to produce a neutral compound?
The Cr3+ ion has a +3 charge, while the O2- ion has a -2 charge. To form a neutral compound, we need two O2- ions to balance the charge of one Cr3+ ion. Therefore, the ions combine in a 1:2 ratio to produce the ionic compound chromium oxide (Cr2O3).
Which is a possible electrochemical cell?
Cr(s) Cr3+(aq) Ag+(aq) Ag(s) Cu(s) Cu2+(aq) Sn4+(aq), Sn2+(aq) Pt(s)
What type of ion is Cr3 plus?
Cr3+ is a cation, specifically a trivalent chromium ion. It has a +3 charge due to the loss of 3 electrons.
What is the formulae of the compound formed by Cr3 plus f minus1?
The compound formed by Cr3+ and F- is chromium(III) fluoride. The chemical formula is CrF3.
Will Cr3 plus have a noble gas configuration?
Yes, Cr3+ will have a noble gas configuration. It will have the electron configuration of argon (Ar) due to the loss of three electrons from the chromium atom.
What species is reduced in the reaction Fe plus AgNo3 plus Fe(No3)3 plus Ag?
Ag+
What is the compound name of Ag2O?
The formula of a compound that contains Ag, N and O is Ag(NO3). The name of the compound is silver nitrate.
What is the balanced equation for silver chlorine silver chloride?
Silver oxide --> silver and (+) oxygenAg2O --> Ag2 + O2BALANCED =2Ag2O --> 2Ag2 + O2
Which element has been reduced in the redox reaction AgNO3 plus Na NaNO3 plus Ag?
Silver (Ag)
What species is reduced in the reaction Fe plus AgNO3 Fe(NO3)3 plus Ag?
Fe + 3AgNO3 ==> Fe(NO3)3 plus 3Ag The oxidation number of Ag in AgNO3 (on the left side) is 1+ and in Ag (on the right side), it is zero. Thus, in this reaction, silver (Ag) has been reduced.
Ag plus H2O would a reaction occur?
Silver (Ag) does not react with water (H2O) under normal conditions because silver is relatively unreactive. However, silver can react with water containing dissolved oxygen or other reactive substances to form silver oxide compounds.
