All organisms use oxidation-reduction reactions to harness energy, and this newly harvested energy is used to produce atp. oxida

tion is defined as the loss of electrons. reduction is the gain of electrons. the energy in fuel molecules (often carbohydrates) is in the form of electrons. when electrons are removed from their high-energy state in fuel molecules (the electron donors), those molecules are oxidized. the electrons must be added to another molecule, which serves as the electron acceptor. as it gains electrons, the electron acceptor is reduced. when these electrons arrive at the final electron acceptor, they are at a lower-energy state compared to their original position in the electron donor. the goal is to harness the energy the electrons lose during this transfer process. in this activity, you will examine three equations and indicate which reactants are electron donors and which are receptors. in addition, you will identify the oxidized product and the reduced product

A student Increases the temperature of a 417 cubic centimeter balloon from 278 K to 231 K. Assuming constant pressure what shoul
WITCHER [35]
Initial Conditions:
Volume= v1= 417 cm³
Temperature= T1 = 278 K
 
Final Conditions:
Temperature= T2 = 231K
Volume = v2 =?

Use the general gas equation;

                                        P1*v1/T1 =  P2*v2/T2
As, the temperature is constant;
 So,
                                               v1/T1 = v2/T2
                                              417/278 = v2/231
                                                  v2= 346.5 cm³

As the ph approaches 0, what happens to the concentration of h3o+ ions?
natta225 [31]

We know that

pH = -log[H+]

the pH value falls in between 0- 7 for acids

As the pH value increases the concentration of [H+] increases.

similarly as the value of pH approaches 0, the concentration of H+ increases

The solution said to become more acidic

Also

[H+] X [OH-] = 10^-14

Thus pH + pOH = 14

hence the concentration of OH- decreases as the pH approaches zero
