Does ethene react with Bromine in the presence of UV light?
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.
What would be the formula and name of the ionic compound formed when iron 2 reacts with bromine?
The reaction of iron(II) salts with bromine is a redox reaction forming iron(III). The aqueous reaction with bromine water is typical:- 2Fe2+ + Br2 -> 2Fe3+ + 2Br- If you started with iron(II) bromide, iron(III) bromide would be formed
When an ionic compound forms between sodium and bromine atoms what occurs?
One electron from each sodium atom is transferred to the outermost shell of a bromine atom, thereby forming a sodium cation and a bromide anion. If the transfer takes place at a temperature below the melting point of the salt sodium bromide, a solid product results, as the ions spontaneously migrate into their lowest energy positions in a crystal lattice of sodium bromide.
What is the balanced equation for copper 2 bromine?
copper 2 bromine is not a chemical name. copper and bromine are both elements. the term "copper 2" suggests divalent copper, ie copper in the Cu++ state. Bromine is almost always a monovalent anion, ie Br-. Copper bromide is then one copper ion and two bromine ions together forming CuBr2.
How are potassium and calcium atoms similar?
There near eachother on the periodic table
Can bromine and caesium be combined?
Yes they can be, forming Caesium bromide
Why does concentrated hydrochloric acid not react with potassium a predicted?
Potassium violently reacts with hydrochloric acid forming the potassium chloride and hydrogen gas.
What class of chemicals is potassium carbonate?
It is a base forming salt, very soluble (as all potassium salts are)
Can potassium dissolve in water?
Yes. potassium will dissolve in water forming potassium hydroxide and hydrogen gas. however, the reaction is very exothermic and will generally catch fire.
Why does bromine have a lower melting point than potassium chloride?
Bromine is a molecular compound Br2 and the intermolecular forces are london dispersion forces. Potassium chloride is an ionic compound forming a lattice with strong electrostatic forces holding the lattice together. Less thermal energy is required to shake solid Br2 apart than that required for KCl
What is the maximum amount of water that can be prepared from the reaction of Br2 with Ca?
Calcium react with bromine forming calcium bromide.
What kind of reaction occurs when potassium is placed in the water?
Metallic potassium, placed in water, will react with water molecules, forming potassium hydroxide, and releasing hydrogen gas. 2K + 2H2O ==> 2KOH + H2
Potassium metal in water?
Potassium will react violently with water, forming potassium hydroxide and hydrogen gas. 2K + 2H2O --> H2 + 2KOH The heat of the reaction will likely ignite the hydrogen, which will subsequently form water.
Is potassium can not be a substance to decomposed by chemical means?
Potassium is an element. Reacting it chemically will produce new chemical compounds but the the nucleus of the potassium ion is not affected, only the outermost electron shell which normally loses an electron forming the K+ cation
Does ethene react with Bromine in the presence of UV light?
Yes, however it doesn't require it either to react. ethene+bromine water→1,2-dibromoethane Ethane reacts with bromine only in the presence of UV forming bromoethane and hydrogen bromide.

Why does potassium tarnish quickly?
Potassium tarnishes very quickly as it is extremely reactive, due to the fact that it has only a single electron in its outer shell. This makes it react quickly with oxygen, forming a layer of potassium oxide around the metal. If you cut the potassium, you will the see the true, silvery coloured metal for a few moments before it tarnishes again.
