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

1. In first reaction reactant a is the electron donor, while b is the electron acceptor,
the oxidized product is c while the reduced product is d

2. in the second equation e is the electron donor, f is the electron acceptor
g is the oxidized product while h is the reduced product.

3. In the third reaction i is the electron donor, j is the electron acceptor , k is the oxidized product while l is the reduced product.

How many moles of copper are there in 6.93 g of copper sample<br>pls be quick​
Alex_Xolod [135]
  • Molar mass of copper=63.5g/mol
  • Given mass=6.93g

\\ \sf\longmapsto No\:of\;moles=\dfrac{Given\:mass}{Molar\:mass}

\\ \sf\longmapsto No\:of\:moles=\dfrac{6.93}{63.5}

\\ \sf\longmapsto No\:of\:moles=0.109\approx 1.11moles

Explain Charles law​
kodGreya [7K]

"Charles Law" is the relationship between "volume-temperature" (V ∝ T).

<u>Explanation</u>:  

Charles Law is basically volume-temperature relationship (V ∝ T). French scientist “Jacques Charles” in 1787 studied effect of temperature on the volume of gases at constant pressure, which described how gases manage to expand when heated. Law stated as “At constant pressure, the volume of a given "mass" of a gas decreases or increases by 1/273 of its volume at 0^{\circ} \mathrm{C} for each one degree rise or fall in temperature”. Formula derived from law is as follows: \mathbf{V}_{\mathbf{t}}=\mathbf{V}_{0}[\mathbf{1}+\mathbf{t} / \mathbf{2} 7 \mathbf{3}] here {V}_{0} is volume of given mass of a gas at 0^{\circ} \mathrm{C}, {V}_{t} is its volume at any temperature t^{\circ} \mathrm{C}. Application of Charles law is hot air balloons.

Which of the following aqueous solutions are good buffer systems?
garri49 [273]

The following aqueous solutions represents good buffer systems:

  • 0.22 M acetic acid + 0.15 M potassium acetate
  • 0.29 M ammonium nitrate + 0.32 M ammonia

<h3>What is a buffer?</h3>

A buffer is a solution used to stabilize the pH (acidity) of a liquid.

A good buffer system is generally known to contain close or equal concentrations of a weak acid and its conjugate base.

Based on the above explanation, the following represents a good buffer system as they are between their weak acid and conjugate base:

  • 0.22 M acetic acid + 0.15 M potassium acetate
  • 0.29 M ammonium nitrate + 0.32 M ammonia
