Answer:

Compost 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, "compost is a mixture dead organic material that can be used as fertilizer"

Suppose you are provided with a 30.86 g sample of potassium chlorate to perform this experiment. What is the mass of oxygen you

oee [108]

Answer:

The mass of oxygen is 12.10 g.

Explanation:

The decomposition reaction of potassium chlorate is the following:

2KClO₃(s) → 2KCl(s) + 3O₂(g)

We need to find the number of moles of KClO₃:

$\eta_{KClO_{3}} = \frac{m}{M}$

Where:

m: is the mass = 30.86 g

M: is the molar mass = 122.55 g/mol

$\eta_{KClO_{3}} = \frac{30.86 g}{122.55 g/mol} = 0.252 moles$

Now, we can find the number of moles of O₂ knowing that the ratio between KClO₃ and O₂ is 2:3

$\eta_{O_{2}} = \frac{3}{2}*0.252 moles = 0.378 moles$

Finally, the mass of O₂ is:

$m = 0.378 moles*32 g/mol = 12.10 g$

Therefore, the mass of oxygen is 12.10 g.

I hope it helps you!

Which of the following chemical reactions is the only reaction shown that would be predicted to occur based on the activity seri

Novosadov [1.4K]

B. Mn + NiBr₂ → Ni + MnBr₂

Explanation:

The reaction that can be predicted of all is Mn + NiBr₂ → Ni + MnBr₂.

The activity series is used to predict the products of single displacement reactions.

The series ranks metals in order of their reactivity. Those higher up in the series are highly reactive metals. Those at the bottom are slightly to non-reactive metals.

For a single displacement reaction to occur, a metal higher up in the activity series displaces one that is lower in the series.

Reaction A will not occur, Ba is higher in the series

Reaction C will not occur, Pt and Au are unreactive

Reaction D will not occur as Zn is lower in the series

Mn is higher in the reactivity series and it will displace Ni from the solution.

For the balanced chemical reaction

musickatia [10]

Answer:

150

Explanation:

C₄H₂OH + 6O2 → 4CO2 + 5H₂O

We can find the equivalent number of O₂ molecules for 100 molecules of CO₂ using a conversion factor containing the stoichiometric coefficients of the balanced reaction, as follows:

100 molecules CO₂ * $\frac{6moleculesO_2}{4moleculesCO_2}$ = 150 molecules O₂

150 molecules of O₂ would produce 100 molecules of CO₂.
