Answer:

Let's use the example of mail, back in the older days they were most likely transported by people. Until people domesticated the horse, messengers or messenger animals, such as birds, could have been used to transport them. Domesticated animals changed the work force for the better, mail was more efficient but it could still take weeks to get certain letters to far away people. As technology advanced, so did transportation, as of today, tradition mail is brought by mail carriers and is still used. The greatest technological success is the email, and can get mail to another country in a matter of seconds. From mail carriers taking months to deliver letters, to a matter of seconds, technology has paved the way for better communication between people in general.

Hope this helps!

Have a great day and stay safe! :))))))

Which is a spectator ion in the reaction between these two solutions?
defon

Im not sure what it is but i will try      

BaCl₂(aq) + Na₂SO₄(aq) = BaSO₄(s) + 2NaCl(aq)

Ba²⁺(aq) + 2Cl⁻(aq) + 2Na⁺(aq) + SO₄²⁻(aq) = BaSO₄(s) + 2Na⁺(aq) + 2Cl⁻(aq)

Ba²⁺(aq) + SO₄²⁻(aq)= BaSO₄(s)

An electrochemical cell is powered by the half reactions shown below.
andrezito [222]
Reduction reactions are those reactions that reduce the oxidation number of a substance. Hence, the product side of the reaction must contain excess electrons. The opposite is true for oxidation reactions. When you want to determine the potential difference expressed in volts between the cathode and anode, the equation would be: E,reduction - E,oxidation. 

To cancel out the electrons, the e- in the reactions must be in opposite sides. To do this, you reverse the equation with the negative E0, then replacing it with the opposite sign. 

Pb(s) --> Pb2+ +2e-      E0 = +0.13 V
Ag+ + e-  ---> Ag           E0 = +0.80 V

Adding up the E0's would yield an overall electric cell potential of +0.93 V.
