We are given with
136 g P4
excess oxygen
The complete combustion reaction is
P4 + 5O2 => 2P2O5
Converting the amount of P4 to moles
136/123.9 = 1.098 moles
Using stoichiometry
moles P2O5 = 1.098 x 2 = 2.195 moles P2O5
Answer : The correct option is, (D) CO₂, BCl₃, and Fe³⁺
Explanation :
According to the Lewis concept, an acid is defined as a substance that accepts electron pairs and base is defined as a substance which donates electron pairs.
(a) 
It is a Lewis-acid because it can accepts electron pairs.
(b) 
It is not a Lewis-acid because it can not accepts electron pairs but it is a base because it can donates and accept hydrogen ion.
(c) 
It is a Lewis-acid because it can accepts electron pairs because it has an incomplete octet and an empty 2p orbital.
(d) 
It is a Lewis-acid because it can accepts electron pairs.
Hence, the ions which behave as Lewis acids are, CO₂, BCl₃, and Fe³⁺
Answer:
Genotypes are related with the collection of genes expressed in the DNA.
Explanation:
Hello,
In genetics, two specific terms define the characteristics of a living thing; a genotype and a phenotype; thus, phenotypes are related with the physical manifestation of genes, for instance, red hair, blue eyes, long arms and others.
On the other hand, genotypes are related with the collection of genes expressed in the DNA, and they could be for equal alleles or for different alleles, in other words, it is the version of DNA the living thing has.
