Copolymer have more than one kind of monomer in its repeating unit.
<h3>What are Copolymers ?</h3>
Those polymers that have more than one kind of monomer in its repeating unit are called Copolymers.
These are useful to modify the properties of polymers that needs more strength , durability etc.
It is a way of improving mechanical properties of a polymer .
A copolymer formed from two dissimilar molecules (as two olefins) is a codimer and the homopolymer and homodimer as the name suggest are made of one similar kind of monomers.
Copolymer have more than one kind of monomer in its repeating unit.

When measuring copper that is collected on a filter paper, the mass measurement obtained will include both the mass of the filter paper and copper.
therefore we have to find the mass of the empty filter paper before copper is on the paper.
the mass of the filter paper alone is 0.27 g
then the mass of copper and filter paper is 0.98 g
therefore to find the mass of copper alone we have to take the difference between the 2 masses
mass of copper = (mass of copper + filter paper ) - mass of filter paper
= 0.98 g - 0.27 g
mass of copper = 0.71 g
Both the Sun and the Earth are sources of heat that power an interconnected set of dynamic systems (lithosphere, hydrosphere & cryosphere, atmosphere, biosphere).
Within the Sun, heat is transferred by radiation and convection, which involves circulation of hydrogen ions. Within the Earth heat is transferred by conduction and convection, which involves circulation of silicates in the mantle and the crust, and by the circulation of iron in the liquid outer core. On the surface of the Earth and the atmosphere, heat emanating largely from the Sun is transferred by convection, which involving the circulation of water and carbon. Both the Sun and the Earth and their atmospheres are layered. Both systems evolve and change.
The molarity of a salt solution made by dissolving 250.0 grams of NaCl in 775 mL of solution is <u>5.52 M</u> .
<u>Explanation:</u>
The molarity of a solution tells one how many moles of <u>solute</u> one can get <em>per liter</em> of solution.One should remember to must convert this volume to liters by using the conversion factor:
1 L = 10³ml
Sodium chloride (NaCl) has a molar mass of 58.44 g per mol , which means that the sample will contain:
This means that the molarity of the solution will be:
Incomplete combustion occurs when the supply of air or oxygen is poor. Water is still produced, but carbon monoxide and carbon are produced instead of carbon dioxide. ... Carbon monoxide is a poisonous gas, which is one reason why complete combustion is preferred to incomplete combustion.
