Answer:
Explanation:
Since the transferred heat is equal to the change in the internal energy, the heat is proportional to the mass of the substance and the temperature change. The transferred heat also depends on the substance so that, for example, the heat necessary to raise the temperature is less for alcohol than for water. Hope that helps!:)
Answer:
c. The reactant that is used up before the others
Explanation:
b. is also correct, because the limiting reactant is completely used up.
a. and d. are wrong. They describe the excess reactant.
Answer:
See explanation
Explanation:
In the voltaic cell, energy is produced by spontaneous chemical reaction. One half cell functions as the anode (in this case it is the Fe/Fe^2+ half cell) while the other half cell functions as the cathode (in this case it is the the Ag/Ag^+ half cell).
At the anode;
Fe(s) -----> Fe^2+(aq) + 2e
At the anode;
2Ag^+(aq) + 2e ------> 2 Ag(s)
Overall cell equation;
Fe(s) + 2Ag^+(aq) ------> Fe^2+(aq) + 2 Ag(s)
Answer:
0.029
Explanation:
Initially, the number the student intends calculating is 29:
From 29 x
but a submutiple of a thousand was introduced in form of mc²:
this implies:
29 x( 1/) :
to make the expression correct: 29 should be 0.029
0.029 x ( 1/)
Answer:
Ag(I)C2H3O2 ....................
Silver only has a single valence value (+1) so you really don't need to put the (I) in the chemical formula.
