When methane is burned out in the ocean
Answer:
Gradual refinement
Explanation:
Gradual refinement is the process whereby the System Development Life Cycle goes through a series of development stages, each stage/phase refining the previous one.
Answer : The enthalpy change for the solution is 166.34 kJ/mol
Explanation :
First we have to calculate the enthalpy change of the reaction.
Formula used :
where,
= change in enthalpy = ?
C = heat capacity of water = 
m = total mass of sample = 2.174 + 127.4 = 129.6 g
= initial temperature = 
= final temperature = 
Now put all the given values in the above expression, we get:
Now we have to calculate the moles of AX added to water.
Now we have to calculate the enthalpy change for the solution.
As, 0.04592 moles releases heat = 7638.36 J
So, 1 moles releases heat = 
Therefore, the enthalpy change for the solution is 166.34 kJ/mol
Answer:
This is like having enough energy to supply the world for centuries with just 1% of the sea's force? The amount of energy in it can supply energy therefore the one drop of tea is able to run her air conditioning for the rest of her life.
Explanation:
The polar covalent bonding occurs when two atoms with different electronegativity form a covalent bond. This type of connection, the electrons are not equally shared. Typically, the atom having higher electronegativity attracts the electrons in the next link to it, thus forming a negative pole in its vicinity, and a positive pole of the next region less electronegative atom.
example: In the molecule HCl, hydrochloric acid, chlorine atom is more electronegative attracting electrons proximity to the bond with the hydrogen atom that is less electronegative, or more electropositive also rated.
hope this helps!.
