What is the reduction half-reaction for the equation below?

Chemistry
1 answer:
Katen [24]3 years ago
3 0

Answer:

MnO_4^-+8H^++5e^-\rightarrow Mn^{2+}+4H_2O

Explanation:

Hello there!

In this case, since redox reactions are characterized by the presence of a reduction reaction, whereby the oxidation of the element decreases, and an oxidation reaction whereby the oxidation of the element increases.

In such a way, for the given chemical equation, we can see Fe is increasing its oxidation state from 2+ to 3+, which means it is oxidized. On the flip side, Mn is being reduced from 7+ (MnO₄⁻) to 2+ and this, the reduction half-reaction is:

MnO_4^-+8H^++5e^-\rightarrow Mn^{2+}+4H_2O

Whereas five electrons are carried.

Regards!

How does the location and design of a house can help control temperature?
Anestetic [448]

Answer:

See detailed explanation.

Explanation:

Hello.

In this case, since each place has specific conditions of temperature, humidity, altitude and others, it is important for the companies building houses to consider all of those factors because they could wear out or affect the customer's lifestyle as the years go by.

More specifically, for temperature, since customers tend to complain and concern about it, there are some strategies in order to control it:

- In terms of location, it is possible to locate the house near to threes covering the sun, build it in a higher altitude since the higher altitude the lower the environmental temperature or just look for a place wherein the temperature is almost constant, for instance, south America.

- In terms of design, it is possible to build the walls and roofs with isolating materials which very likely to keep the inner part of the house from high temperatures or just installing heaters inside them.

Of course, there may be more strategies in order to control it.

Best regards.
