Answer:
A silicon atom has 14 electrons around the nucleus, and of these, there are 4 valence electrons on the outermost orbital. When this is made into a single crystal, it can be used as a material for semiconductor products. When it crystalizes, the nuclei share electrons and they bond with 8 electrons around each nucleus.
Answer:
Transition states have partially formed bonds whereas intermediates have fully formed bonds.
Explanation:
According to Wikipedia, a transition state "is defined as the state corresponding to the highest potential energy along a reaction coordinate. It is easily seen as an energy maxima.
A reaction intermediate is defined as any unstable molecular entity formed as a result of interaction between reactants. This entity undergoes further chemical changes to yield the products of the chemical reaction. Intermediates occur at an energy minima in the reaction coordinate.
The bonds in a transition state are partially formed because a transition state often involves a simultaneous breaking and making of bonds while an intermediate contains fully formed chemical bonds
The answer would be: C. 160.3 J/mol*K
To solve this question, you need to know the equation for Gibbs free energy formula. Entropy is expressed as delta S. The temperature would be expressed as T. Don't forget that temperature use Kelvin as unit, not Celsius
The formula would be:
G= H- T*S
130.5 kJ/mol= 178.3kJ/mol - (25+273.15K)*S
(298.15K)*S=178.3kJ/mol - 130.5 kJ/mol
S= (47.8kJ/mol)/ 298.15K=
S= 0.1603 kJ/mol*K= 160.3 J/mol*K ------> 1kJ= 1000J
