Which of the following properties of soil is most dependent on soil moisture?
a. horizonation
b. consistency
c. cation-exchange capacity
d. soil reaction

We generally test the Soil consistence by crushing the soil pad with a finger. It completely depends upon the soil moisture.

We categorize the soil as

1)  Moist soil:

loose – The soil particles are not coherent, they are lose apart.

friable – can be crushed with a slight pressure applied through fingers.

firm –  can be crushed with a slightly more pressure applied through fingers.

2) Wet soil:  Plastic and sticky

3) Dry Soil:  It can be soft and hard

The answer is: d. soil reaction.

Explanation:

Soil moisture is the amount of water per volume of land in a land.

The maximum moisture capacity of the soil depends on the type of soil, its development, the vegetation present and the uses of the soil.

Soil moisture at a given time will depend, among other factors, on rainfall, and evapotranspiration that have occurred.

The answer is: d. soil reaction.

answer: the value of enthalpy change will be -152.80 kj.

solution:

pressure = 1atm , temperature = = 298 k

given that pressure and temperature are same in both gases , the number of moles of both gases can be determined by the ideal gas equation.

according to reaction 3 moles no are reacting with 1 mol of ,then 0.49 mol of no will react with moles of ozone that is 0.16 moles of ozone. since, no is limiting reagent and is an excessive reagent.

enthalpy change for the reaction between the given volumes of the gases is :
