Answer:
Explanation:
The chemical equation for the reaction is :
The standard enthalpy of formation of the above equation is as follows:
= -1274.4 kJ/mol
= -277.7 kJ/mol
= -393.5 kJ/mol
where ;
= stochiometric coefficients of products
stochiometric coefficients of reactants
= formation standard enthalpy of products
= formation standard enthalpy of reactants
For ;
The standard enthalpy of formation of of the reactant and the products are :
The is as follows:
(to kJ/K)
Given that;
at T = 25°C = ( 25 + 273) K = 298 K
As is negative; the reaction is spontaneous
= negative
= positive; Therefore , the reaction is spontaneous at all temperature , We can then say that the spontaneity of this reaction is dependent on temperature.
Genomic evolution
Hope this helps :) you would probably want to do more research into Genomic evolution to give a more detailed answer, but that's the basic answer
Answer:
A
Explanation:
it's a because model is like the same thing as walking on a Runway but it's like a model in the medical field
In the question, the number of atoms per unit cell is required for:
A) Polonium (Po)
In polonium, the structure is simple cubic, meaning there are 8 corner atoms, which add up to one atom per unit cell.
B) Manganese (Mn)
The structure of the Mn can be considered to be a body centered cubic (BCC) and the number of atoms for this is 8 corner atoms and 1 central atoms, making a total of 2 atoms per unit cell.
C) Silver (Ag)
Silver has a face centered cubic (FCC) unit cell structure, where there are 8 corner atoms and 6 atoms on the faces, so there are a total of 4 atoms per unit cell.
Answer:
Solar Energy.
Explanation:
There is more solar radiation hitting their surface, which means they can produce more electricity. Solar energy is more valuable in places with expensive electricity. If two solar panel systems in different cities have the same energy output, savings will be greater in the city with the highest kWh prices.
