How can a redox reaction be used as a source of electrical energy?
stepladder [879]
A redox reaction be used as a source of electrical energy only when two half-reactions are physically separated. <span>The electrons that are released at the anode flow through the wire, producing an electric current. Galvanic cells therefore transform chemical energy into electrical energy that can then be used to do work.</span>

What is the name of IBr4?<br> And is it covalent or ionic?
BlackZzzverrR [31]

Answer: The name of the IBr_4 is Iodine tetrabromide and it is a covalent compound.

Explanation:

Inter-halogen compounds are compounds which composed of two different halogen atoms. For example ;ICl_3,IF_5 etc.

The naming is done by first writing the central atom symbol's name followed by the prefix corresponding to the number of atoms of another halogen atom like: Mono for 1, di ,for 2 tri for 3, tetra for 4 , penta for 5 etc. After this name of the another halogen is written with suffix 'ide' in the end.

The name of the IBr_4 is Iodine tetra bromide.

In halogen compounds, the difference in electronegativities is not so large due to which they form covalent compounds by the means of sharing the electrons. Hence the Iodine tetrabromide  covalent compound.

What would you observe when zinc is added to solutions of iron II sulphate? write the chemical reaction that takes place.​
kompoz [17]

Answer:

When zinc is added to the solution of iron sulphate, the colour of iron sulphate solution changes. It is because zinc is more reactive than iron, it displaces iron from its solution of iron sulphate and a grey precipitate of iron and a colourless solution of zinc sulphate is formed.

Explanation:

Zn(s) + FeSO4(aq) -----> ZnSO4(aq) + Fe(ppt.)

What chemical property is given to a biomolecule with a hydroxyl (--oh) functional group?
marin [14]

A biomolecule with a hydroxyl (--oh) functional group is given the polar chemical property since organic molecules with an OH group are polar.

 

A part of a larger molecule is made up by a functional group. The hydroxyl group (-OH) that characterizes alcohols, an oxygen with a hydrogen attached, is an example of it. This group can be found on any number of different molecules.

 

Functional groups have characteristic chemistries, just as elements have unique properties., although perhaps not identically, to an -OH on another molecule. Although perhaps not identically to an -OH on another molecule, an -OH group on one molecule will tend to react similarly.
