Answer:

<u><em>Compost</em></u> is a mixture dead organic material that can be used as fertilizer

Explanation:

Compost is a natural organic fertilizer that is prepared with different organic materials, providing nutrients and improving soil structure. Compost converts waste into fertilizer and valuable organic matter for soils.

The transformation of organic matter is carried out with composting, that is, the controlled decomposition of organic materials. Among them are fruits, pruning remains, vegetables, among others. The result of this procedure is a completely organic product that improves the soil structure and provides the necessary nutrients to the soil, all naturally.

Compost has a wide variety of advantages. Among them, it can be mentioned that urban waste is reduced considerably because it minimizes environmental problems related to its treatment and transportation. The soil structure will also be improved, helping with water retention, ventilation and the possible effects of frost. And the earth will eventually contain more organic matter and more nutrients; and it is possible to avoid the use of chemical fertilizers that can negatively affect the soil or the health of people. In addition, the lack of these substances produces an increase in the amount of microorganisms beneficial to the life cycle. Earthworms and other organisms will aerate the earth, prevent it from composting and favor the roots of plants.

So, <u><em>"compost is a mixture dead organic material that can be used as fertilizer"</em></u>

The expression below was formed by combining different gas laws. V is proportional to StartFraction n T over P EndFraction. Whic
Ronch [10]

Answer:

The Ideal gas law

Explanation:

From the given question, we have:

V \alpha \frac{nT}{P}

where each variable has its usual meaning.

Thus,

V = \frac{nRT}{P}

where R is the ideal gas constant

cross multiply to have;

PV = nRT

This implies that the volume of the gas is directly proportional to the number of moles of the gas.

Therefore, the law can be used to determine the relationship between the volume and number of moles is the ideal gas law.

Compare<br> Ion and Radical<br> Atom and molecule<br> Organic and inorganic compounds
horrorfan [7]

Answer:

'An ion has a non-zero electric charge. A radical has an atom with unfilled electron shells and so is very reactive, but is electrically neutral.'

'Atoms are single neutral particles. Molecules are neutral particles made of two or more atoms bonded together.'

'The primary difference that lies between these organic compounds and inorganic compounds is that organic compounds always have a carbon atom while most of the inorganic compounds do not contain the carbon atom in them.'

Does any solid Ag₂CrO₄ form when 2.7x10⁻⁵g of AgNO₃ is dissolved in 15.0 mL of 4.0x10⁻⁴MK₂CrO₄?
e-lub [12.9K]

Molarity of Ag+ is less than the molar solubility thus ppt will not occur.

Balanced reaction-:

<h3>2AgNO3(aq)+K2CrO4(aq)→Ag2CrO4(s)+2KNO3(aq)</h3>

Moles of AgNO3=mass(g)molar mass (g/mol) =2.7×10−5g / 169.86 gmol

=1.589⋅10^−7 mol

Molarity of Ag+=moles of solute(L)=1.589⋅10−7 mol0.015 L=1.059⋅10−5M

Ksp of Ag2CrO4

=[Ag+]2[CrO42−]

1.2⋅10−12=[2s]2[s]

4s3=1.2⋅10−12

s=6.69⋅10−5 M

Molarity of Ag+ is less than the molar solubility thus ppt will not occur.

<h3>What is the molarity calculation formula?</h3>

The volume of solvent required to dissolve the provided solute is multiplied by the ratio of the moles of the solute whose molarity has to be computed. (M=frac{n}{V}) The molality of the solution that needs to be computed in this case is M. n is the solute's molecular weight in moles.
