It has more lines in it compared to hydrogen emission spectrum. It is mainly because the helium atom has more electrons than a hydrogen atom. Therefore, more electrons get excited when we pass a white light beam through a helium sample, and it causes the emission of more spectral lines

Answer:

D. Point into Leaf: water(H₂O), carbon dioxide (CO₂) sunlight, Point away from leaf: Sugars, oxygen (O₂)

Explanation:

Photosynthesis is the process used in the production of chemical energy in the form of energy containing organic compounds and oxygen from atmospheric carbon dioxide and liquid water enabled with the energy captured from light (mainly Sunlight) by the chlorophyll in green plants and other organisms

The basic chemical reaction involved in a photosynthesis reaction is presented as follows;

{}                                          ↓

{}       CO₂           +  H₂O (l)  →   C₆H₁₂O₆   +    O₂

Explanation:

The term suspension means mixing of small and light particles together which are not dissolved in a fluid.

Therefore, clay, slit, and sand would be carried by suspension as they have small particles as compared to small pebbles and large rocks.

In a rock, there might be substance which are soluble in water. These soluble substances are therefore, continuously removed from the rock by the action of water.

Hence, holes will appear in the rock leading to rills and rough surface. Ultimately, the rock will either decompose or fall into pieces. On acidification of water by organic and inorganic solvents, the dissolution of rock increases.

Thus, it is concluded that in solution, rocks are dissolved by salts and acids.
