A voltaic cell spontaneously converts1) electrical energy to chemical energy(2) chemical energy to electrical energy(3) electric
Varvara68 [4.7K]
A voltaic cell spontaneously converts chemical energy to electrical energy. The correct option among all the options given in the question is option "2". Actually voltaic cell is an electrochemical cell that converts the chemical contained within it by the process of chemical reaction to produce electrical energy. The voltaic cell contains an anode and a cathode. Anode is an electrode where the oxidation occurs and cathode is the electrode where reduction occurs. The oxidation and the reduction part occurs in two separate parts of the cell known as half-cell.

Step 2: Now that you have counted the atoms on each side, add coefficients to balance the equation. Check your work by updating
Alja [10]

Answer:

The answers to your questions are given below.

Explanation:

__ NaBr + CaF₂ —> __ NaF + CaBr₂

The above equation can be balance as follow:

NaBr + CaF₂ —> NaF + CaBr₂

There are 2 atoms of F on the left side and 1 atom on the right side. It can be balance by writing 2 before NaF as shown below:

NaBr + CaF₂ —> 2NaF + CaBr₂

There are 2 atoms of Na on the right side and 1 atom on the left side. It can be balance by writing 2 before NaBr as shown below:

2NaBr + CaF₂ —> 2NaF + CaBr₂

Now, the equation is balanced.

Atom >>>> Reactant >>>> Product

Na >>>>>> 2 >>>>>>>>>>> 2

Br >>>>>>> 2 >>>>>>>>>>> 2

Ca >>>>>> 1 >>>>>>>>>>>> 1

F >>>>>>> 2 >>>>>>>>>>>> 2

how much heat is released when 70.9g of water at 66C cools to 25C? The specific heat of water is 1 cal/gC
Serga [27]

Answer:

-12162.47 joules (or -12000 joules when accounting for significant figures)

Explanation (btw I used 1 cal as 4.184 joules because SI units are better):

q = m c delta T

q = (70.9) (4.184) (25 - 66)  

q = (70.9) (4.184) (-41)

q = -12162.47 joules
