The balanced equation is:
2NaCl + 2 H2o → 2 NaOH + Cl2 + H2
1- we put 2 NaCl to balance Cl2 on the other side.
2- we put 2 NaOH to balance Na
3- We put 2 H2O to balance H & O on the to sides
Answer:
A: heat energy
Explanation:
because as we light up the bulb it gives us light energy
but when we touch it we feel that it is hot (heat energy)
the heat energy given of is not for our use and goes to waste
D.
Q= m·ΔT·C(specific heat)= n·M·ΔT·C=10,5mol·27 g/mol· 194,5(225-30,5)·0,9=49600J=49,6kJ.
