How is clayey soil useful for crops?

Chemistry
1 answer:
joja [24]2 years ago
7 0

Answer:

Clayey soil is rich in humus and very fertile, so it is suitable for growing cereals like wheat and gram. Such soil is good at retaining water.Clayey is known to be useful for crops. Because the particle size in this soil is very fine, it has the ability to retain more amounts of water. - This makes it easy for crops to access water as it is very essential for the growth of the plant. - Some of the crops need a high amount of water in order to grow.Clayey soil is made up of fine particles that are tightly packed and increases soil density and strength. It is rich in nutrient content in the form of organic matter or humus so, it is very fertile soil. It has excellent water retaining a capacity.

Which of the following molecules can form hydrogen bonds? Group of answer choices NH3 NaH HI BH3 CH4
Len [333]

Answer:

NH₃

Explanation:

The hydrogen bond is a specially strong type of dipole-dipole interaction. For a hydrogen bond to occur, a molecule must have a hydrogen atom and a very electronegative atom, such as nitrogen, oxygen or fluorine. The hydrogen atom has a positive charge density while the heteroatom has a negative charge density.

<em>Which of the following molecules can form hydrogen bonds? </em>

NH₃ YES

NaH NO

HI NO

BH₃ NO

CH₄ NO

What is the mass of ca(oh)2 in 110. mL of 1.244 M ca(oh)2 solution
stealth61 [152]
<em>V= 110mL = 110cm³ = 0,11dm³</em>
<em>C = 1,244 mol/L = 1,244 mol/dm³</em>


C = n/V
n = 1,244×0,11
<u>n = 0,13684 moles</u>

<em>mCa(OH)₂ = 74 g/mol</em>


1 mole Ca(OH)₂ ------------ 74g
0,13684 ---------------------- X
X = 74×0,13684
<u>X = 10,12616g</u>

Find the density of a substance with a mass of 45 grams and a volume of 9
Over [174]

Density = mass / volume

Density = (45g) / (9 [volume units])

Density = 5g / [volume unit]

There was no specification on the units of volume.  However, whatever it may be, just replace the square brackets with the value and your units will be correct.

Calculate the molarity of 48.0 mL of 6.00 M H2SO4 diluted to 0.250 L
const2013 [10]

Answer:

The answer is 1.15m.

Since molality is defined as moles of solute divided by kg of solvent, we need to calculated the moles of H2SO4 and the mass of the solvent, which I presume is water.

We can find the number of H2SO4 moles by using its molarity

C=nV→nH2SO4=C⋅VH2SO4=6.00molesL⋅48.0⋅10−3L=0.288

Since water has a density of 1.00kgL, the mass of solvent is

m=ρ⋅Vwater=1.00kgL⋅0.250L=0.250 kg

Therefore, molality is

m=nmass.solvent=0.288moles0.250kg=1.15m
