Answer:
6 oxygens on the product side
Explanation:
1) balance the equation:
C2H4 + 3O2 → 2CO2 + 2H2O
2) calculate the number of oxygens on the product side
2CO2=4
2H2O=2
The prediction is that B. The electrons will flow to the zinc anode where a negative charge will build up and eventually halt the reaction.
<h3>What is zinc?</h3>
This is known as a chemical element, of the periodic table, that is essential to life and is one of the most widely used metals. Zinc is of considerable commercial importance.
Without the salt bridge, positive and negative charges will build up around the electrodes causing the reaction to stop.
Hence, we know that the purpose of the salt bridge is to keep the solutions electrically neutral and allow the free flow of ions from one cell to another.

Answer:
they all reacted the same
Explanation:
Explanation:
Sorry, I don't know, but I can tell you that when an atom, or a body, has the same amount of positive charges (protons) and negative charges (electrons), it is said to be electrically neutral. ... The net charge corresponds to the algebraic sum of all the charges that a body possesses.
