What else can I help you with?
Does phenol react with bromine?
Yes, at room temperature bromine reacts with phenol and forms 2,4,6-tribromo phenol.
What changes in color occur when bromine or KMnO4 reacts with an alkane?
Bromine reacts with an alkane to produce a colorless solution, due to the formation of a colorless alkyl halide. On the other hand, potassium permanganate (KMnO4) reacts with an alkane to form a brown precipitate of manganese dioxide.
What is the formula for manganese(viii) arsenide?
The formula for manganese(VII) arsenide is Mn3As7.
What element reacts to make bromide ions?
Bromide ions are derived from the element bromine (Br). When a bromine atom gains one electron, it forms a bromide ion (Br-).
Does Bromine react with air?
Yes, bromine reacts with air to form bromine vapors. Bromine reacts with oxygen present in the air to form bromine oxides.
What happens when bromine reacts with sodium?
When bromine reacts with sodium, it forms sodium bromide. The reaction is a displacement reaction where sodium displaces bromine from its compound to form sodium bromide. The reaction is highly exothermic and produces a bright orange flame.
What is bromine plus hydrogen?
When bromine reacts with hydrogen, it forms hydrogen bromide. The balanced chemical equation for this reaction is Br2 + H2 → 2HBr.
How can you tell whether a compound reacts with bromine?
You can test if a compound reacts with bromine by adding bromine water to the compound. If the compound reacts with bromine, the characteristic reddish-brown color of the bromine water will fade as it reacts with the compound. This reaction is often used to test for the presence of unsaturated bonds in organic compounds.
What is the formula of manganese II bromide?
The formula for manganese(II) bromide is MnBr2. This is because manganese has a +2 oxidation state, while bromine has a -1 oxidation state, requiring two bromine atoms to balance the charge of one manganese atom.
What molecular compound is MnBr5?
Manganese pentabromide is the molecular compound MnBr5. It is composed of one manganese atom and five bromine atoms.
How does Mn bond to Br?
Ionic bonds. Manganese is a metal and bromine is a nonmetal, therefore, they react by means of an oxidation-reduction reaction, forming ions, manganese donates electrons and bromine receives them.
What is the mass of aluminum metal that reacts to give 11.1g of manganese metal?
To find the mass of aluminum that reacts to give 11.1g of manganese, you need to use the molar ratio between aluminum and manganese in the reaction. Once you have the balanced equation, you can calculate the molar mass of manganese and aluminum, and then determine the mass of aluminum needed to produce 11.1g of manganese.
