Answer:
Antibiotics destroy bacteria
Answer:
Dry more clothes at the same time so that there is less room for electric forces.
Explanation:
Answer : The value of
for this reaction is 36.18 kJ
Explanation :
First law of thermodynamic : It states that the energy can not be created or destroyed, it can only change or transfer from one state to another state.
As per first law of thermodynamic,

where,
= internal energy of the system
q = heat added or rejected by the system
w = work done
As we are given that:
q = 38.65 kJ
w = -2.47 kJ (system work done on surrounding)
Now put all the given values in the above expression, we get:


Therefore, the value of
for this reaction is 36.18 kJ
True. Its simple how i remeberd was the bone has 650,000 cells and the bone has 65% hydroxyapatite
