1) chromium(III) nitrate is acidic, because it is the salt of weak base (chromium(III) hydroxide Cr(OH)₃) and strong acid (nitric acid HNO₃).
2) sodium hydrosulfide is basic, because it is the salt of strong base (sodium hydroxide MaOH) and weak acid (hydrogen sulfide H₂S).
3) zinc acetate is little basic, because zinc hydroxide (Zn(OH)₂) is stronger base than acetic acid (CH₃COOH).
Explanation:
When carbon atom tends to form single bonds then its hybridization is 
, when carbon atom tends to form double bond then its hybridization is 
and when a carbon atom is attached to a triple bond or with two double bonds then its hydridization is sp.
For example, in HCN molecule there is a triple existing between the carbon and nitrogen atom.
So, hybridization of carbon in this molecules is sp. Moreover, nitrogen atom is also attached via triple bond and it also has a lone pair of electrons. Hence, the hybridization of nitrogen atom is also sp.
Thus, we can conclude that s and p type of orbitals overlap to form the sigma bond between C and N in H−C≡N:
Answer:
c. abc₃
Step-by-step explanation:
1. a atoms
There are eight corners, each containing an a atom.
No. of a atoms = 8 × ⅛
No. of a atoms = 1
=====
2. b atoms
There is one central b atom.
=====
3. c atoms
There are six faces, each containing a c atom.
No. of a atoms = 6 × ½
No. of c atoms = 3
=====
4. Formula
The simplest formula is abc₃.
In regards to the given question, option “1” is the correct
option. When propane is burnt to complete combustion, it results in the
formation of two completely different substances. It actually forms a mixture
of water vapour and carbon dioxide. When NaCl or sodium chloride is melted, it
does not result in the formation of any new substance and so option “2” cannot
be the correct answer. With regards to deposition of carbon dioxide and solidification
of water, no new substance gets formed and so can be neglected as the answer to
the question.
Carbon atoms make up organic compounds.
Organic compounds are molecules that contain carbon atoms covalently bonded to hydrogen atoms (C-H bonds). Many organic compounds are formed from chains of covalently-linked carbon atoms with hydrogen atoms attached to the chain (a hydrocarbon backbone).
