Answer:
It conducts electricity
It conducts heat
Water is needed for rusting
Explanation:
Metals refer to elements that are found towards the left hand side of the periodic table of elements. They are found in groups 1- 13 and few of them are also found at the bottom of groups 14 and 15.
Now these metal have certain properties that are general to all of them. two of these properties listed among the options in the question are;
i) They conduct electricity
ii) They conduct heat
These properties apply to all metals universally.
Rusting is an electrochemical reaction in which hydrated iron III oxide is formed. In the electrochemical reaction, water in intimately involved in the process. Hence; oxygen and water are required for rusting to take place.
C. Sulfuric acid is a strong oxidizing agent.
Explanation:
The above two reactions xcan also be written in form of single chemcial equation:
![FeCl_3+K(SCN)\rightleftharpoons KCl+[Fe(SCN)]Cl_2(blood-red)](https://tex.z-dn.net/?f=FeCl_3%2BK%28SCN%29%5Crightleftharpoons%20KCl%2B%5BFe%28SCN%29%5DCl_2%28blood-red%29)
1. Color of ferric chloride solution is yellow. This is due to presence of ferric ions which have yellow color in their aqueous solutions.
2. KSCN has the colorless solution. This due to potassium ion forms colorless aqueous solution.
3. On mixing, KSCN with 
we will get blood red color solution of ![[FeSCN]Cl_2](https://tex.z-dn.net/?f=%5BFeSCN%5DCl_2)
.

Photosynthesis is the process by which plants use energy from the sun to convert carbon dioxide and water into glucose and oxygen. The equation for photosynthesis is,
6CO₂ + 6H₂O + light energy --> C₆H₁₂O₆ + 6O₂
This process occurs in the chloroplasts of the plant, using light energy to split water molecules into oxygen and hydrogen. The oxygen is released into the atmosphere while the hydrogen combines with carbon dioxide to form glucose. This glucose is then converted into other compounds, such as cellulose, which the plant uses for energy.
The equation of photosynthesis shows how plants use carbon dioxide and water, combined with light energy from the sun, to produce glucose and oxygen. This process is crucial for life on Earth, as it is the primary way that plants and other photosynthetic organisms convert carbon dioxide into oxygen.
The process of photosynthesis is closely related to the carbon cycle, as it helps to keep the levels of CO₂ in the atmosphere balanced. Photosynthesis removes carbon from the atmosphere and stores it in the form of organic compounds, such as glucose.
As plants use glucose for energy, they release some of this carbon back into the atmosphere in the form of CO₂. This process helps to maintain a steady balance of CO₂ in the atmosphere, which is crucial for life on Earth.
