Ans: The entropy change for the given reaction is 93.3 J/K
Given reaction:
Br2(l) → Br2(g)
ΔS = ∑n(products)S⁰(products) - ∑n(reactants)S⁰(reactants)
= 1 mole* S°(Br2(g)) - 1 mole*S°(Br2(l))
= 1 mole *245.5 J/mol-K - 1 mole*152.2 J/mol-K
= 93.3 J/K
They are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.
<h3>What is a covalent bond?</h3>
A covalent bond consists of the mutual sharing of one or more pairs of electrons between two atoms.
Sometimes, while naming the chemical compounds, a problem arises when compounds with “ao” and “oo” are written with -ide name. Conventionally, they are converted into a single “o”.
For example, the “ao” in the dichlorine hept-ao-xide (
). This “ao” in the
can be converted into “o”. As the result, the correct name of this compound would be dichlorine hept-o-xide.
Hence, they are converted into a single “o” when "ao" or "oo" are together when naming covalent bonds.

Answer:
C.Nucleus
Explanation:
The cells are all prokaryotic . This means they do not have a nucleus or any other structures which are surrounded by membranes . ... It is called chromosomal DNA and is not contained within a nucleus.
A believe it’s called a “group”
