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 antibiotic doxycycline is used to treat Lyme disease. A 100 mg dose of the antibiotic consists of 59.5 mg of C, 5.40 mg of H
never [62]

Answer:

C₁₁H₁₂NO₄

Explanation:

In order to determine the empirical formula of doxycycline, we need to follow a series of steps.

Step 1: Determine the centesimal composition

C: 59.5 mg/100 mg × 100% = 59.5%

H: 5.40 mg/100 mg × 100% = 5.40%

N: 6.30 mg/100 mg × 100% = 6.30%

O: 28.8 mg/100 mg × 100% = 28.8%

Step 2: Divide each percentage by the atomic mass of the element

C: 59.5 /12.0 = 4.96

H: 5.40/1.00 = 5.40

N: 6.30/14.0 = 0.450

O: 28.8/16.0 = 1.80

Step 3: Divide all the numbers by the smallest one

C: 4.96/0.450 = 11

H: 5.40/0.450 = 12

N: 0.450/0.450 = 1

O: 1.80/0.450 = 4

The empirical formula of doxycycline is C₁₁H₁₂NO₄

During which phase change does the arrangement of water molecules become more orderly?
KatRina [158]
The phase change in which the water molecules become most orderly is the freezing. This is the process of changing water as liquid to its solidified form. The process of freezing is an exothermic which means that for this to occur, heat should be removed from the system.
