Answer:
The answer to your question is the letter A. 1
Explanation:
Data
Chemical reaction
(NH₄)₂CO₃ ⇒ NH₃ + CO₂ + H₂O
Reactants Elements Products
2 Nitrogen 1
1 Carbon 1
8 Hydrogen 5
3 Oxygen 3
This reaction is unbalanced
(NH₄)₂CO₃ ⇒ 2NH₃ + CO₂ + H₂O
Reactants Elements Products
2 Nitrogen 2
1 Carbon 1
8 Hydrogen 8
3 Oxygen 3
Now, the reaction is balanced,
The coefficient for Carbon dioxide is 1
Carbon fixation is the process of conversion in which carbon-dioxide (inorganic carbon) converts into organic compounds with the help of living organisms and example of this process is photosynthesis.
From the definition, it is confirmed that there is no formation of carbon dioxide takes place i.e. carbon doesn't joined with oxygen molecules.
Thus, carbon fixation is the process in which carbon atoms are added to the molecules of hydrogen and oxygen to make carbohydrates.
Answer:
Δ S° > 0
Explanation:
Entropy -
In a system, the randomness is measured by the term entropy .
Randomness basically refers as a form of energy that can not be used for any work.
The change in entropy is given by the change in heat per change in temperature.
- When solid is converted to gas entropy increases,
As the molecules in solid state are tightly packed and has more force of attraction between the molecules, but as it is converted to gas, the force of attraction between the molecule decreases and hence entropy increases.
So,
The particles of the substance , if are tightly held by strong force of attraction will decrease the entropy ,
And
If the particles are loosely held , the entropy will increase .
From the reaction given in the question ,
Cu₂O (s) + C (s) → 2 Cu (s) + CO (g)
Considering the states of the reactant and the product ..
The product formed i.e. CO is in gaseous species , hence , the entropy increases .
Ionic compounds are made up of cations and anions.
So, C would be the correct answer
Heat = "A source" of energy due to a "temperature" difference.
