Ca 2 Br

If you are combining 2 Calcium and one Bromide atoms, it would not end up as Ca 2 Br - ...you must cross the charges, as in the charges those atoms have in their ionic forms, to get the final formula (no matter how many atoms you start with, as long as you balance the equation later: (Br^1- charge) + (Ca^2+ charge) --> CaBr(subscript 2) once you cross the Calcium's 2+ charge to the subscript of the bromine, and the bromine's 1- charge to the (invisible) subscript of the calcium, 1. Hope this helps! :D

What is the ionic formula for Ca 2 Br-1?

The ionic formula for Ca 2 Br-1 is CaBr2. This is derived by balancing the charges of calcium (Ca2+) and bromine (Br-). Two bromine ions are needed to balance the double positive charge of the calcium ion.


What is the chemical formula for Ca and Br?

All you have to do is flip the numbers and reduce. If you have Ca+2 and Br-, Switch the numbers so you get CaBr2. 1 and 2 do not have any common factors so you don't have to reduce! CaBr2 is the final answer.


What is the chemical formula that forms from a chemical reaction between calcium and bromine?

Ca+2 Br-1 -----> these are the ions and their chargesCa+2 Br-1 Br-1 ------> the charges have to add up to zero, so one -1 Br ion is added to cancel out the +2 Ca.CaBr2 -----> simplify


Is Ca2 plus likely to form How about Br- Ne- Ne plus?

Ca(2+) and Br- are common ions; the neon ion probable doesn't exist.


What is the oxidation number for Ca in Ca Br?

The molecular formula should be CBr4. The oxidation numbers are -1 for each Br, +4 for C.


Which compound will form by the joining of Ca and Br?

Calcium bromide (CaBr2) will form when calcium (Ca) and bromine (Br) react together. In this compound, one calcium atom will combine with two bromine atoms to create a neutral ionic compound with a 1:2 ratio of calcium to bromine atoms.


What is the oxidation number of Br in Br?

-2 for each O, +5 for Br


What type of bond is Ca-Br?

The bond between calcium (Ca) and bromine (Br) is an ionic bond. Calcium will donate electrons to bromine, forming a positively charged calcium ion and a negatively charged bromine ion, resulting in strong electrostatic attraction between the two ions.

Mercurous carbonate plus calcium bromide?

When mercurous carbonate (Hg2CO3) reacts with calcium bromide (CaBr2), it forms mercurous bromide (Hg2Br2) and calcium carbonate (CaCO3). This is a double displacement reaction where the positive ions in the compounds switch places to form the products.

PbBr2 soluble in water?

It is very slightly soluble in water.In a saturated solution:[Pb2+] = 1.2x10-2 mol/L[Br-] = 2.4x10-2 mol/Lbecause [Pb2+]*[Br-]2 = Ks = 6.3*10-6 and [Br-] = 2*[Pb2+]
