It shows that the population is moving towards a more organic and natural way of growing crops. Rather than using fertilizer and putting toxins on the plants that we eat from, we are getting smarter and growing food naturally. Thus not killing ourselves in the process.

Answer:

The decrease in fertilizer use does not mean that there is a decrease in agricultural production in America. On the contrary, there could be an increase in production even using fewer fertilizers.

The reason is simple, THE TECHNOLOGY.

Explanation:

Currently there are many new methods to save fertilizer products in the field and make crops more efficient. This is called precision agriculture.

With these methods, for example, images taken with drones or satellites (with multispectral or hyperspectral cameras) can be used to assess the status of a crop, the lack of nutrients from the soil, and even if there are pests or diseases on the plats; All this allows the farmer to apply the fertilizer or other products, only in the area that presents the problem and not in the entire crop.

A sample of table sugar has a mass of 5.432g a) calculate the number of moles in the sample
Temka [501]

The number of particles of atoms depends on the ratio of their composition in the compound

<h3>Further explanation</h3>

Given

5.432 g of table sugar

Required

moles of sample

moles of C, H and O

number of atoms

Solution

Table sugar : Sucrose : C₁₂H₂₂O₁₁

  • moles of sample :

= 5.432 : 342,3 g/mol

= 0.016

  • moles of C, H, and O :

C = 12 x 0.016 = 0.192

H = 22 x 0.016 = 0.352

O = 11 x 0.016 = 0.176

  • number of atoms :

C = 0.192 x 6.02 x 10²³ = 1.16 x 10²³

H = 0.352 x 6.02 x 10²³ = 2.12 x 10²³

O = 0.176 x 6.02 x 10²³ = 1.06 x 10²³
