SThe  missing   coefficient  for  the  skeleton   equation  below  is  as  follows

skeleton   equation

Cr(s)  +  Fe(No3)2(aq)  ------> Fe (s)   +  Cr(NO3)3  (aq)
the  missing  coefficient  are  is   as  follows

 2 Cr(s)   +  3  Fe(NO3)2  ---> 3 Fe (s)  +  2 Cr(NO3)3

This  is  obtained   by  making  sure  all  the   molecules  are  balanced  in  both  sides

In a redox reaction, why does an element's oxidation number increase
Kazeer [188]
If the element is oxidized, then it's oxidation number would increase.

Let's say we have the following reaction.
2H2O --> O2 + 2H2

To the left, the oxidation number of O is -2, as it is bonded to two H, which is always H+. To the right, we have O2, and all gases have a oxidation number of 0 (zero). We say that O has been oxidized.

PLEASE HELP!
White raven [17]

Benzene be B

Toluene be T

We have made then one lettered to make things easier

  • \sf P^0_B=95.1mmHg,P^0_T=28.4mmHg
  • \sf x_B=x_T=0.5

\\ \rm\Rrightarrow \dfrac{P^0_B-P_B}{P^0_B}=x_B

\\ \rm\Rrightarrow 95.1-P_B=95.(0.5)

\\ \rm\Rrightarrow 95.1-P_B=47.55

\\ \rm\Rrightarrow P_B=47.55mmHg

And

\\ \rm\Rrightarrow \dfrac{P^0_T-P_T}{P^0_T}=x_T

\\ \rm\Rrightarrow 28.4-P_T=28.4(0.5)

\\ \rm\Rrightarrow P_T=14.2mmHg

Total vapour pressure

  • 28.4+95.1
  • 123.6mmHg

This increase in blood pHpH due to hyperventilation disrupts O2O2 transport by causing the deprotonation of various residues of
Genrish500 [490]

The question is incomplete as it does not have the options which has been provided in the attachment.

Answer:

1. sudden decrease

2. Respiratory alkalosis

Explanation:

Hyperventilation is a condition caused by the excess removal of the CO₂ from the blood which leads to the decrease in the pCO₂ of the arteries.

This decrease can cause fainting and death of the individual due to the malfunctioning of the body parts, especially the brain.

The decrease in the CO₂ amount of the blood causes the formation of bicarbonate and H⁺ ions which leads to respiratory alkalosis.

Therefore the selected options are correct.
