What is Magnesium bromide + Chlorine's product

What type of reaction is this? thanks guys-Chlorine is more reactive than bromine(In group IV reactivity decreases as you go down the group), so chlorine could displace bromine from its compound. The

Help with chemistry!!!!!! not understanding

Chemistry question .. Help

A strip of sodium metal reacts with chlorine gas to form sodium chloride, better known as table salt. From your knowledge of periodic trends, explain why elemental sodium and chlorine react so readily

How many molecules are in 3.78 moles of PCL3

Im not getting this.-You know Avagadros number 6.02 x 10^23 atoms in one mole. And you have 3.78 moles. Now its just unit analysis... 3.78 moles PCl3 x ((6.02 x 10^23 molecules)/1 mol). Moles will can

How many different P–O bond lengths are observed in the H3PO4 molecule

please answer it correctly for me to get through a test, i will vote for best answer-well, it is a resonance structure so, there will be at least one P=O bond which is shorter than the other P-O bonds

Calculate the mass of a sample of gold that occupies 0.591 cm3. The density of gold is 19.3 g/cm3.

Answer in units of g-19.3 g/cm3 x 0.591 cm3 = 11.41 grams of gold. Thats it.-10.0167g/cm3

What is the purpose of an empirical formula

I believe the longer version of a formula is more useful, and you would be able to know what chemical it is by looking at it. On the other hand, empirical formulas are the shorter form, and so i am no

Why do we call H2O water instead of hydrogen oxide

When we call other compounds such as CO2, carbon dioxide? Is it just to make it easier since its so common and apparent in our lives?-The word water goes through many, many languages, as well as throu
