Answer:
False
Explanation:
Valence electrons depend of their what group they're in.
Answer:
The correct option is;
It is used during photosynthesis to capture sunlight
Explanation:
During photosynthesis, light energy from the Sun is converted and stored in sugars as chemical energy. The Sun light energy is used in the formation of complex sugars such as glucose from the combination of water from the ground and carbon dioxide from the atmosphere while oxygen is released as the byproduct. Organisms are then able to obtain energy from the glucose as well as carbon fiber
The chemical equation for the reaction is as follows;
6CO₂ + 12H₂O + light energy → C₂H₁₂O₆ + 6O₂ + 6H₂O
Carbon, Water, GLucose, Oxygen, Water
dioxide
<u>Answer:</u>
<em>Adsorption is a phase conversion process that changes a mixture component from one state of matter to another is a </em><u><em>false statement.</em></u>
<em></em>
<u>Explanation:</u>
Adsorption is a process in which a solute accumulates on the surface of an adsorbent to form an atomic film.
The solute may be a gas or a liquid and the adsorbent will be a solid.
The resultant atomic film what we get is known as an adsorbate.
So molecules accumulate on the external or internal surface of the solids.
Answer:
132 m/s
Explanation:
So, you divide the distance by the time.
Answer:
Cl⁻ is the reducing agent.
Explanation:
The redox reaction is as follow:
MnO₂ + 4H⁺ + 2Cl⁻ → Mn²⁺ + 2H₂O + Cl₂
One should know the following terms,
Reducing agent:
An atom or element which tends to lose electron during a chemical reaction and get itself oxidized. In above reaction Cl⁻ is reducing agent as it carries a negative charge (means it has one extra electron) on the reactant side while, it has zero oxidation state on the product side. It means going from -1 to 0 the Cl lost one electron hence, it is an reducing agent according to definition.
Oxidizing Agent:
On the other hand oxidizing agent is an element or compound which tends to accepts electron(s) and get itself reduced. In above reaction Mn has an oxidation state of +4 on reactant side and after gaining electron from Cl it has changed to +2 on the product side. Hence, it has reduced but has oxidized the Cl atom so it is an oxidizing agent according to definition.
