Answer:
CnH2n+2 is the general formula for paraffins, also known as alkanes, which are saturated compounds with the general formula CnH2n+2, where n is the number of carbon atoms in the molecule. Methane (CH4), often known as C1, is the most basic of the alkanes and has the simplest structure. Normal paraffins (also known as n-paraffins or n-alkanes) are straight-chain molecules with no branches.
Explanation:
Alkanes are referred to as paraffins because they have a low affinity for a general reagent when heated. Alkanes, on the other hand, are non-reactive chemicals. When exposed to extreme circumstances, they have responses.
This dome-like shape forms due to the water molecules' cohesive properties, or their tendency to stick to one another. ... Water molecules at the surface (at the water-air interface) will form hydrogen bonds with their neighbors, just like water molecules deeper within the liquid.
Answer:
DOUBLE DISPLACEMENT (mutual exachange of ions in aqueous form)
Ca is more reactive than Fe
hence it will displace Fe from ferrous nitrate solution and form Calcium Nitrate and Ferrous Sulphate will be formed
GOOD LUCK WITH THE FUTURE! :)
