Answer:
Wouldn't rust because zinc will lose electrons more readily than iron and will therefore oxidize first.
Explanation:
This process whereby rusting of steel is prevented by coating the steel with a layer of zinc is known as galvanization.
Now, in this process, the steel object will be coated in a thin layer of zinc. This coating will prevent oxygen and water from reaching the underneath metal since the zinc will also act as a sacrificial metal.
Now, Zinc is used because it has a lower reduction potential than iron and thus it will get easily more oxidized than iron. Which means the zinc will lose electrons more readily than iron.
Also, since zinc has a lower reduction potential, it is therefore the more active metal. Thus, even if the zinc coating is scratched and the steel is exposed to moist air, the zinc will still get to oxidize before the iron.
Planck suggested that light/energy was absorbed/released in certain amounts, called quanta.
Answer:
Explanation:
Hello there!
In this case, since the integrated rate law for a second-order reaction is:
Thus, we plug in the initial concentration, rate constant and elapsed time to obtain:
Best regards!
<u>Answer:</u>
<u>For a:</u> The balanced equation is
<u>For c:</u> The balanced equation is
<u>Explanation:</u>
A balanced chemical equation is one where all the individual atoms are equal on both sides of the reaction. It follows the law of conservation of mass.
The given unbalanced equation follows:
To balance the equation, we must balance the atoms by adding 2 infront of both and and 3 in front of
For the balanced chemical equation:
The given balanced equation follows:
The given equation is already balanced.
