6.022 x 10^23
Explanation:
There are 20 zeros and the 022 are 3 more places.
Answer:
Polymerization
Explanation:
Several natural and man-made organic compounds are enormous molecules which contains hundreds of thousands of atoms per molecule.
The giant molecules formed are produced through the process of polymerization.
Polymerization is the linking of monomers through chemical reactions to form long chain polymer molecules.
Monomers are small molecules that are joined to form polymers.
Synthetic plastics are derieved from synthetic polymers. These synthetic materials are very useful and vital due to their great size. Their size premits a certain complexity of structure which makes the molecules disposed in a regular pattern with respect to one another. They stretch out nearly to alongside of one another or coil up independently. The polymerization of monomers to form plastics fosters the various uses these giant molecules are put to.
1. Antelope Canyon was formed by the erosion of Navajo Sandstone.
2. The appearance of water is determined
by the way the water molecules are moving.
3. Moist rising air near the Equator cools and condenses into clouds and, later, rain.
Answer: d) -705.55 kJ
Explanation:
Heat of reaction is the change of enthalpy during a chemical reaction with all substances in their standard states.
Reversing the reaction, changes the sign of 
On multiplying the reaction by 
, enthalpy gets half:
Thus the enthalpy change for the given reaction is -705.55kJ
