In redox half-reactions, a more positive standard reduction potential means I. the oxidized form has a higher affinity for elect

qwelly [4]

Answer:

The 1st and 4th options are correct

I.the oxidized form has a higher affinity for electrons

IV. the greater the tendency for the oxidized form to accept electrons

Explanation:

Half reaction can be described as the oxidation or reduction reaction in a redox reaction.it is In the redox rection there is a change in the oxidation states of Chemical species involved. the oxidized form in the redox has a higher affinity for electrons and the greater the tendency for the oxidized form to accept electrons.

Standard reduction potential which is also referred to as standard cell potential can be described as the potential difference that exist between cathode and anode of the cell. In the standard reduction potential most times the species will be reduced which is usually analysed in a reduction half reaction.

(Standard Hydrogen Electrode) is utilized when determining the Standard reduction or potentials of a chemical specie. this is because of Hydrogen having zero reduction and oxidation potentials, as a result of this a measured potential of any species is compared with that of Hydrogen, the difference helps to know the potential reduction of that particular specie.

Over long time scales the solubility-temperature feedback (below), can affect climate. An increase in atmospheric CO2 concentrat

Mars2501 [29]

The fact that CO2 is released from oceans due to further rise in temperature is an example of a negative feedback.

A negative feedback is one in which the process that produces the feedback is interrupted. That is, the process is stopped as a result of the feedback received.

In this case, CO2 which leads to global warming dissolves in the ocean which serves a large sink for the gas. However, as the increase in ocean temperatures causes decrease in solubility of CO2, more CO2 is released leading to further temperature rise. This is an example of a negative feedback loop.

The density of a pure liquid at 25 degrees Celsius was calculated by determining the mass and volume of a sample of the liquid.

adelina 88 [10]

Answer

The density of the liquid is 0.82 g/mL.

Explanation:

From the question given above, the following data were obtained:

Mass of empty flask = 18.990 g

Mass of flask + liquid = 39.439 g

Volume of liquid = 25 mL

Density of liquid =..?

Next, we shall determine the mass of the liquid. This can be obtained as follow:

Mass of empty flask = 18.990 g

Mass of flask + liquid = 39.439 g

Mass of liquid =.?

Mass of liquid = (Mass of flask + liquid) – (Mass of empty flask)

Mass of liquid = 39.439 – 18.990

Mass of liquid = 20.503 g

Finally, we shall determine the density of the liquid as follow:

Mass of liquid = 20.503 g

Volume of liquid = 25 mL

Density of liquid =..?

Density = mass / volume

Density of liquid = 20.503 / 25

Density of liquid = 0.82 g/mL
