Which of these is a sign of salinization in crop plants? a. yellowing of leaves b. wilting of seedlings c. dead patches on leaves d. enlarged seedlings

The correct answer is option C.

Explanation:

Salinization is the process in which water soluble salts acculturates in the soil and hinders the absorption process of water from the soil performed by the roots of the plants.

Due to lack of water supply in the plants from roots dead patches on leaves starts appearing which indicates the salinization of soil.

Salinization not only effects the crops or plants but also effects the fertility of the land and microorganism living the soil.

Wilting Of Seedlings

Explanation:

the only liquid elements at standard temperature and pressure are bromine (br) and mercury (hg). although, elements caesium (cs), rubidium (rb), francium (fr) and gallium (ga) become liquid at or just above room temperature.

explanation:

"standard molar enthalpy:

h2o ( liquid water ) : - 285.8 kj/mole

h2o ( water vapor ) : - 241.8 kj / mole.

δhrxn = - 241. 8 - ( - 285.8 )= -241.8 + 285.8 = 44.0

answer: 44.0 kj"
