Answer:
letter C is a structure most like that of slate
Answer:
= 4
Explanation:
The pH of a solution is given by;
pH = - log [H+] , while
pOH = - log [OH-]
But; pH + pOH = 14
Therefore;
pH = 14 - pOH
= 14 - 10
= 4
Answer:
3) an applied electric current
Explanation:
An electric source is used in an electrolytic cell.
Answer : The energy released is -3319.7 KJ.
Solution : Given,
Mass of methane = 59.7 g
Molar mass of methane = 16 g/mole
The value of is in negative that means the energy is releasing.
First we have to calculate the moles of methane.
Moles of methane =
Now we have to calculate the amount of energy released.
The given reaction is,
From the reaction, we conclude that
1 mole of methane releases -890 KJ/mole of energy
3.73 moles of methane releases of energy
Therefore, the energy released is -3319.7 KJ.
