Answer:
Characteristics of the genetic code. The genetic code consists of 64 triplets of nucleotides. These triplets are called codons.With three exceptions, each codon encodes for one of the 20 amino acids used in the synthesis of proteins.
Explanation:
To illustrate the Lewis structure,
P has 5 valence electrons
O has 6 valence electrons (each for 4 oxygen)
And finally, for every negative charge, there is an additional valence electron
We should add these all up = 5 + 24 + 3 = 32 valence electrons
With this, we can be guided to illustrate the lewis structure as P as central atom and the 3 oxygen each with a single bond with P and 1 oxygen with a double bond with P. We place the valence electrons until octet rule is satisfied,
we will be left with 12 lone pairs for phosphate ion.
Answer:
Here's what I get
Explanation:
SiO₂ + 4HF ⟶ SiF₄ + 2H₂O
The molar ratios are the same as the coefficients in the balanced equation.
Some of the molar ratios are
SiO₂:HF = 1:4
SiO₂:SiF₄ = 1:1
SiO₂:H₂O = 1:2
HF:SiF₄ = 4:1
HF:H₂O = 4:2
SiF₄:H₂O = 1:2
