Answer:
Polymerization, any process in which relatively small molecules, called monomers, combine chemically to produce a very large chainlike or network molecule, called a polymer. The monomer molecules may be all alike, or they may represent two, three, or more different compounds.
Chemical change. The heat from frying an egg causes the egg's protein to change permanently in texture and in appearance through a process.
Answer:
11.25 moles of O₂.
Explanation:
We'll begin by writing the balanced equation for the reaction. This is illustrated below:
C₃H₈ + 5O₂ —> 3CO₂ + 4H₂O
From the balanced equation above,
1 mole of C₃H₈ reacted with 5 moles of O₂.
Finally, we shall determine the number of mole of O₂ needed to react with 2.25 moles of C₃H₈. This can be obtained as follow:
From the balanced equation above,
1 mole of C₃H₈ reacted with 5 moles of O₂.
Therefore, 2.25 moles of C₃H₈ will react with = 2.25 × 5 = 11.25 moles of O₂.
Thus, 11.25 moles of O₂ is needed for the reaction.
First reaction is a Condensation Reaction. As a amall molecule (water) is evolved with the production of ether this is called as condensation of alcohols.
Second reaction is Addition Reaction also known as electrophilic addition reaction. Here HBr is added across double bond to yield alkyl halide.
Third reaction is Elimination Reaction. In this reaction tertiary alcohol is treated with base. A unsaturated compound is formed in this reaction.
Last reaction is Substitution Reaction (Aromatic Electrophilic substitution reaction. In this case a electrophile on benzene (Proton) is substituted with another electrophile (Bromine)
Answer:
Option D is correct
Explanation:
The individual mass of reactants in the reaction are
Calcium Oxide (CaO) = 
amu
Carbon dioxide (CO2) 
amu
Since this reaction is a simple addition reaction in which no mass of the reactants is wasted. Also, no energy is released accompanied by conversion of mass into energy.
Hence, total mass of reactants would be equal to the mass of the product.
Thus, mass of calcium carbonate i.e CaCO3 is
amu
Hence, option D is correct
