Answer:
The correct answer is: Alkali Metals
Explanation:
The chemical elements that belong to the group 1 of the periodic table are known as the alkali metals. The alkali metals belong to the s-block and are highly reactive in nature.
The alkali metals are lithium (chemical symbol Li), sodium (chemical symbol Na), potassium (chemical symbol K), rubidium (chemical symbol Rb), caesium (chemical symbol Cs), and francium (chemical symbol Fr).
Therefore, lithium, sodium, potassium are examples of alkali metals.
B.would be very weak
C.would occur as normal
Answer:
Option (B)
Explanation:
Lake effect snow generally occurs when the cold winds extracts the water content (moisture) from the relatively warmer lakes and carries further and precipitates back on the land areas in the form of snow. Much of the snow is originated from the lake Ontario and it deposits on the nearby terrestrial areas.
So, when the Lake Ontario is cold enough like the air mass that blows in the continental arctic, then it indicates that the lake effect snow would be comparatively very much weak.
Thus, the correct answer is option (B).
Plants need energy for Reproduction, Photosynthesis, Growth, and Development amongst others.
To produce their own food energy, which is referred to as "photosynthesis," plants need water and sunlight. They need energy because they are living things.
Photosynthesis is the process by which plants turn solar energy into sugar. Light energy is utilized by photosynthesis to transform carbon dioxide and water.
Numerous biological functions, such as growth and reproduction, require energy. Therefore, energy is absolutely essential.

Answer:
Explanation:
There are three types of interactions involved between the particles when solution are formed.
1 : Solute - solute interaction:
2 : Solute - solvent interaction:
3 : Solvent - solvent interaction:
1 : Solute - solute interaction:
It is the inter-molecular attraction between the solute particles.
2 : Solute - solvent interaction:
It involve the inter-molecular attraction between solvent and solute particles.
3 : Solvent - solvent interaction:
It involve the intermolecular attraction between solvent particles.
Solutions are formed if the intermolecular attraction between solute particles are similar to the attraction between solvent particles.
Exothermic process:
The process will exothermic when solute solvent bonds are formed with the release of energy and energy required to brake the solute-solute particles and solvent solvent particles are less.
Endothermic process:
The process will be endothermic when energy required to break the solute-solute particles and solvent solvent particles are higher than energy released when solute solvent bonds are formed .
Solution formation involves three particle interactions: solute-solute, solvent-solvent, and solute-solvent interactions. Breaking solute-solute and solvent-solvent interactions requires energy, so these are endothermic processes. Solute-solvent interaction formation releases energy, making it an exothermic process.
When a solution forms, three main types of interactions between particles are involved: solute-solute interactions, solvent-solvent interactions, and solute-solvent interactions. The formation of a solution is essentially a sort of balance between these interactions.
Solute-solute interactions are the attractions between particles (atoms, molecules, or ions) within the solute. The breaking of these attractions is an endothermic process, as it requires energy to be put into the system to overcome these attractions.
Solvent-solvent interactions are the attractions between particles within the solvent. Like solute-solute interactions, the breaking of solvent-solvent interactions is also an endothermic process.
Solute-solvent interactions occur between particles of the solvent and solute when a solution is formed. This is the point at which the solvent 'dissolves' the solute. The formation of these new attractions releases energy, making it an exothermic process.
