What if the negative sign is outside the exponet?
im not sure that is possible what you are saying is that 63- I have never seen this in my 8 years since first taking algebra. the negative sign outside the exponent can mean a negative charge on chemistry. lets say you have a copper ion... copper = Cu2- this means is has two extra electrons that it wants to share
When do you need to use a roman numeral in the name of a compound?
Roman numerals are typically used in compound names to indicate the oxidation state of an element. This is necessary when the element can have multiple oxidation states and is written as a cation in the compound. For example, iron can exist in the +2 or +3 oxidation state, so the compound name "iron(II) chloride" specifies that it is the +2 oxidation state of iron.
What is the stock name for Cu2 plus?
The stock name for Cu2+ is copper(II).
What is the correct cell notation for the reaction 2Au plus aq plus Cus 2Ausplus Cu2 plus aq?
Cu(s) | Cu2+(aq) Au+(aq) | Au(s)
What is the formula for Copper III sulfite?
Copper does not form +3 oxidation number. So there cant be a formula like that.
Calculate the standard emf of a cell that uses the Mg Mg2 plus and Cu Cu2 plus half cell reactions at 25 degrees C?
Cu + Mg2 --------> Cu2 + Mg Cu --------------> Cu2 + 2e Mg2 + 2e --------> Mg Cu --------------> Cu2 + 2e (E = +0.35) Mg2 + 2e --------> Mg (E = -2.36V) +0.35 + (-2.36) = -2.01V --------------------------------------… Mg + Cu2 --------> Mg2 + Cu Mg --------------> Mg2 + 2e Cu2 + 2e --------> Cu Mg --------------> Mg2 + 2e (E = +2.36V) Cu2 + 2e --------> Mg (E = -0.35V) +2.36 + (-0.35) = +2.01V
What is the complete ionic equation for copper II oxide plus hydrochloric acid yield copper II chloride plus water?
Cu2+ + O2- + H+ + Cl- = Cu2+ + 2 Cl- + H2O
What is the formula for copper II hypoborite?
The formula for copper(II) hypobromite is Cu(BrO).
What is the balanced net ionic equation for the reaction Cu2 plus?
E2xoy4=cu8
Is Cu plus 2 a cation or anion?
Cu is a cation. When Cu loses two electrons, it forms the Cu2+ cation.
What is the molarity of Cu2 plus if a 0.1025 gram sample of copper metal is dissolved in 35mL of concentrated HNO3 to form Cu2 plus ions and then water is added to make a total volume of 200.0 mL?
To find the molarity of Cu2+ ions, first calculate the moles of Cu2+ from the given mass of copper. Next, use the total volume of the solution to calculate the molarity. The molarity of Cu2+ ions in the solution is 0.377 M.
Why analysis of Cu from brass solution is considered as an iodometric titration?
Copper in brass can be oxidized to Cu2+ by iodine in a redox reaction. The iodine acts as the titrant in the reaction and the copper is being titrated. It is considered an iodometric titration due to the involvement of iodine in the titration process.
What is the formula for copper 2?
The formula for copper(II) is Cu^2+. In other words, copper commonly forms ions with a 2+ charge.
What is the chemical formula for copper ll?
The chemical formula for copper (II) is Cu^2+. When copper loses 2 electrons, it forms a 2+ cation.
