Chemistry
1 answer:
dmitriy555 [2]3 years ago
8 0

Answer:

Eªcell > 0; n = 2

Explanation:

The reaction:

I2 (s) + Pb (s) → 2 I- (aq) + Pb2+ (aq)

Is product favored.

A reaction that is product favored has ΔG < 0 (Spontaneous)

K > 1 (Because concentration of products is >>>> concentration reactants).

Eªcell > 0 Because reaction is spontaneous.

And n = 2 electrons because Pb(s) is oxidizing to Pb2+ and I₂ is reducing to I⁻ (2 electrons). Statements that are true are:

<h3>Eªcell > 0; n = 2</h3>

An important Similarly between photosynthesis and cellular respiration is that both process
adelina 88 [10]

Answer:

Similarity between photosynthesis and cellular respiration is that both process :

<u>Involve production of energy </u>

<u>Exchange of gases</u>

<u>Goes through electron chain reactions</u>

<u></u>

Explanation:

<u>Photosynthesis</u> : It is the process in which green plants containing chlorophyll prepare their food in the presence of Sunlight , water and carbon dioxide.This process occur inside chloroplast .

Here Food is prepared.Oxygen and food is produced as a result of photosynthesis .

<em><u>The electrons triggers the reaction of food formation</u></em>.

<em><u>Energy is released during photosynthesis.</u></em>

<em><u>Gaseous exchange between CO2 and O2 occur.</u></em>

<u>Respiration </u>:

It is the process in which living organism converts oxygen and food to water and carbon dioxide . Here energy is released in the form of ATP. It take place inside the mitochondria of the cell.

<u><em>Exchange of Gases occur between organism and environment.</em></u>

<em><u>Here , mitochondrial electron transport occurs to produce ATP</u></em>.

Hence , similarity between photosynthesis and cellular respiration is that both process:

<u>Involve production of energy </u>

<u>Exchange of gases(carbon dioxide and oxygen)</u>

<u>Goes through electron chain reactions</u>

Which statement best explains how organ systems work together to remove wastes?
soldier1979 [14.2K]

Answer:

B

Explanation:

Carbon Dioxide is one of waste produced from Our cells during respiration. The circulatory system carries Carbon Dioxide from cells either in haemaglobin in RBC or plasm. The Carbon Dioxide being carried to blood cappilaries near alveoli before diffused into alveoli and then being removed away by respiratory system in the process of respiration while we exhale
