M₁ = mass of water = 75 g
T₁ = initial temperature of water = 23.1 °C
c₁ = specific heat of water = 4.186 J/g°C
m₂ = mass of limestone = 62.6 g
T₂ = initial temperature of limestone = ?
c₂ = specific heat of limestone = 0.921 J/g°C
T = equilibrium temperature = 51.9 °C
using conservation of heat
Heat lost by limestone = heat gained by water
m₂c₂(T₂ - T) = m₁c₁(T - T₁)
inserting the values
(62.6) (0.921) (T₂ - 51.9) = (75) (4.186) (51.9 - 23.1)
T₂ = 208.73 °C
in three significant figures
T₂ = 209 °C

Explanation:
(NH4NO3), a salt of ammonia and nitric acid, ....4 and 3 are sub script
A neutralization reaction is a chemical reaction where an acid and a base are combined with the intent of producing a neutral pH level.
Explanation:
Organic compounds are defined as the compounds which contain carbon as their main element. For example, 
is an organic compound.
Generally, organic compounds are non-polar in nature and due to the presence of covalent bonding organic compounds have low melting point.
As compound A melts at 
and is soluble in water. This means it is an ionic compound as it has high melting point and it is also polar in nature.
Whereas compound B melts at 
and is insoluble in water. This means that this compound has covalent bonding and it is also non-polar in nature
. Hence, it is more likely to be organic in nature.
Thus, we can conclude that compound B is more likely to be an organic
compound.
