The answer is 0.365:100.
v/c ratio represents ratio of speed of an electron (v) to the speed of light (c).
How is the speed of an electron calculated?
- The speed of an electron (v) is given by Bohr's model as-
Now, for the first excited state, n = 2.
e - Charge of electron = 
×
C
h - Plank's constant = 
×
ε₀- permittivity 
×
- Put the above data in the formula-
- Now, the speed of light, c =
×
- Thus, the v/c ratio for an electron in the first excited state is calculated as-
= 
- Hence, the v/c ratio = 0.365:100.

Explanation:
Hello there!
In this case, according to the given chemical reaction, it is possible to evidence the 4:3 mole ratio between oxygen and iron (II) chloride; thus, we can compute the moles of the latter that are consumed by the given molecules of the former:
Now, since we have a 0.945-M solution of this iron (II) chloride, the corresponding volume turns out to be:
Best regards!
Water behaves as a base in this reaction.
The Bronsted-Lowry definition is applied, because the reaction involves the transfer of H+ from one reactant to the other.
A Bronsted-Lowry base is defined as a substance that accepts a proton.
Because water gains a proton to form H3O+ in this particular reaction, it acts as a base
a. Elemental percent composition is the mass percent of each element in the compound.
The formula for mass elemental percent composition =

b. The given reaction of cisplatin is:
According to the balanced reaction, 1 mole of 
gives 1 mole of .
Now, calculating the number of moles of in 100.0 g.
Number of moles = 
Molar mass of = 
Number of moles of = 
.
Since, 1 mole of gives 1 mole of . Therefore, mass of cisplatin is:
For mass of 
:
Molar mass of = 
Since, 1 mole of gives 2 mole of . Therefore, mass of is:
the first step in the mechanism is the acid-catalyzed generation of an enol and then electrophilic addition of bromine and cation is formed because of the destabilization effect of the electronegativity of oxygen
The ability of an atom or functional group to draw electrons to itself is known as an electronegativity in chemistry. An atom's electronegativity is influenced by both its atomic number and how far away from its charged nuclei its valence electrons are located.
The ability of an atom to draw shared electrons in a covalent connection is referred to as electronegativity. The stronger an element attracts the shared electrons, the higher its degree of electronegativity.
The propensity of an atom to attract other atoms when it is combined is known as an element's electronegativity. Additionally, a pair of bound electrons are shared. In contrast, an element's electropositivity refers to an atom's propensity to contribute electrons while also withdrawing from covalent connections.
