I think 2 mg is D...Mg is B....I don't know the rest...
Answer:
B 2° alcohol may reduce to aldehyde
Explanation:
Ionic compounds are formed between oppositely charged ions.
A binary ionic compound is composed of ions of two different elements - one of which is a positive ion(metal), and the other is negative ion (nonmetal).
To write the empirical formula of binary ionic compound we must remember that one ion should be positive and other ion should be negative, then only the correct formula should be written. To write the empirical formula the charges of opposite ions should be criss-crossed.
First empirical formula of binary ionic compound is written between
First Formula would be
Second empirical formula is between
Second Formula would be
Note : When the subscript are same they get cancel out, so would be written as
Third empirical formula is between
Third Formula would be :
Forth empirical formula is between
Forth Formula would be : or
Note- The subscript will be simplified and the formula will be written as .
The empirical formula of four binary ionic compounds are :
Answer:
a. Manganese(IV) oxide
b. Mercury(I) chloride
c. Iron(III) nitrate
d. Titanium(IV) chloride
e. Copper(II) bromide
Explanation:
The IUPAC nomenclature is regulated by International Union of Pure and Applied Chemistry which is used in organic chemistry for naming of the organic chemical compounds.
a. Manganese(IV) oxide is IUPAC name of manganesse dioxed
. It is an inorganic compound having the formula MnO2.
b. Mercury(I) chloride is IUPAC name of mercurous chloride
. It is also known as the mineral calomel and have a chemical formula Hg2Cl2.
c. Iron(III) nitrate is IUPAC name of ferric nitrate
. It have a chemical formula Fe(NO₃)₃.
d. Titanium(IV) chloride is IUPAC name of titanium tetrachloride - . It have a chemical formula TiCl4.
e. Copper(II) bromide is IUPAC name of cupric bromide with chemical formula CuBr2 or Br2Cu.
Explanation:
Ionic compounds are formed when two opposite charge atoms combine together. Therefore, there is strong force of attraction between the ions.
In order to break this ionic bond, high heat is required. As a result, the boiling point of ionic compounds is high.
Out of the given options, , KCl, and NaCl are all ionic compounds because the bond formation in these compounds is due to the transfer of electrons.
Hence, all these solutions have high boiling point.
Whereas is a covalent compound, that is, it is formed by sharing of electrons. There is weak force of attraction between iron and chlorine atoms thus, has low boiling point.
Therefore, we can conclude that solutions with highest boiling point are as follows.
- 1 molar solution.
- 1 molar KCl solution.
- 1 molar NaCl solution.
