Answer:
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:
Whereas five electrons are carried.

The number of moles of air present is 0.056 mole
<h3>What is the ideal gas equation?</h3>
The ideal gas is one in which molecules do not attract or repel each other.Many gases like oxygen,nitrogen, carbon di oxide can be treated as the ideal gases as particular temperature and pressure.The real gases at high temperature and lower pressure can be treated as ideal gases.
The given data in the question is
Volume = 1.35 L
Pressure (P) = 750 torr
Temperature (T) = 17 °C = 17 + 273 = 290 K
Gas constant (R) = 62.396 L•torr/mol•K
The number of moles (n) =?
How to determine the number of moles:
The number of moles present can be obtained by using the ideal gas equation as illustrated below:
Divide both sides by RT
Hence, the number of moles of air present is 0.056 mole

Answer: Double Replacement
Explanation: When one of the elements in the compound is replaced by another element. In a single replacement reaction, Minnie Mouse leaves Mickey Mouse for Goofy. This happens when a compound is broken down into separate elements, or the opposite of synthesis.
It may seem a little silly but i hope it helps
4.7 ft is equal to 55 in.
To find out how many inches are in 4.7 ft, you have to multiply 4x12 because there are 12 in in a ft. Since 4x12=48, just at the 7 in to 48 and you’ll get 55 in.
Answer:

- <u><em>2)NH</em></u><em><u>₃</u></em>
Explanation:
The answer choices of this question are:
<h2 /><h2>Solution</h2>
The key to answer this question is to realize that <em>NH₃</em> is a gas at the given temperatures.
The solutilibty of all gases always decreases when the temperature increases. Thus, the solubility of NH₃ will decrease when the temperature rises from 10ºC to 50ºC.
The reason for this behavior of gases is that the temperature and the kinetic energy of the particles are directly proportional. Thus, as the temperature incrases the kinetic energy of the particles increases.
As the kinetic energy of the molecules of gas in the liquid solution increases, their speeds also increase, meaning that more molecules will escape from the solution to the gas phase, leaving the soluton with less dissolved gas molecules.
