Answer:

In chemistry, in general terms, a substrate is a substance that other substances can react with and cause it to change into something else by the reaction.

Explanation:

The word “substrate” can have different meanings, it depends on which science we are talking about.

In chemistry, in general terms, a substrate is a substance that other substances can react with and cause it to change into something else by the reaction.

In biochemistry, the enzyme substrates are organic materials where an enzyme acts to cause a reaction. The enzyme just acts as a catalyst and is not affected by the reaction, as it does not change its chemical structure.

In biology, a substrate is the material where organisms grow and live in optimal conditions and with the necessary nutrients.

In geology, the layers found beneath the soil are called substrates.

Answer:

Option A.

2Na + 2H2O —> 2NaOH + H2

Explanation:

To know which option is correct, we shall do a head count of the number of atoms present on both side to see which of them is balanced. This is illustrated below below:

For Option A:

2Na + 2H2O —> 2NaOH + H2

Reactant >>>>>>> Product

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

4 H >>>>>>>>>>>> 4 H

2 O >>>>>>>>>>>> 2 O

Thus, the above equation is balanced.

For Option B:

2Na + 2H2O —> NaOH + H2

Reactant >>>>>>> Product

2 Na >>>>>>>>>>> 1 Na

4 H >>>>>>>>>>>> 3 H

2 O >>>>>>>>>>>> 1 O

Thus, the above equation is not balanced.

For Option C:

2Na + H2O —> 2NaOH + H2

Reactant >>>>>>> Product

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

2 H >>>>>>>>>>>> 4 H

1 O >>>>>>>>>>>> 2 O

Thus, the above equation is not balanced.

For Option D:

Na + 2H2O —> NaOH + 2H2

Reactant >>>>>>> Product

1 Na >>>>>>>>>>> 1 Na

4 H >>>>>>>>>>>> 5 H

2 O >>>>>>>>>>>> 1 O

Thus, the above equation is not balanced.

From the illustrations made above, only option A is balanced.

1. Create a diagram of your electroplating apparatus (an electrolytic cell). Then submit your drawing with the following terms l

Anestetic [448]

A picture of the electroplating apparatus can be found attached. The nail (cathode) is completely submerged and that is where reduction happens. In the other side, the copper strip is (anode) where oxidation happens. The electron flow happens from the anode to the cathode. The positive charge of the battery is attached to the anode while the negative side is attached to the cathode.
