Answer:
Heat, temperature, and thermal energy are related because they all work with each other.
Explanation:
First of all, everything start's off with temperature. It starts off low. But when heat is added to it, it rises and the temperature goes up. This causes thermal energy to the objects touching it. The hotter it is the faster the particles move and the more kinetic energy they have.
Answer:
0.01836 M
Explanation:
Again the reaction equation is;
Fe(s) + Mn2+(aq) → Fe2+(aq) + Mn(s)
E°cell= 0.77 V
Ecell= 0.78 V
[Mn2+] = 0.040 M
[Fe2+] = the unknown
n=2
From Nernst's equation;
Ecell= E°cell- 0.0592/n log Q
0.78= 0.77 - 0.0592/2 log [Fe2+] /[0.040]
0.78-0.77= - 0.0592/2 log [Fe2+] /[0.040]
0.01/ -0.0296= log [Fe2+] /[0.040]
-0.3378= log [Fe2+] /[0.040]
Antilog(-0.3378) = [Fe2+] /[0.040]
0.459= [Fe2+] /[0.040]
[Fe2+] = 0.459 × 0.040
[Fe2+] = 0.01836 M
Answer:
20.27 mol
Explanation:
454 L x (1 mol/22.4 L) = 20.27 mol
Answer:
Molecular compounds are pure substances formed when atoms are linked together by sharing of electrons while ionic compounds are formed due to the transfer of electrons.
Molecular compounds are made due to covalent bonding while ionic compounds are made due to ionic bonding.
