<u>Answer:</u>

"Precision agriculture" is a farm management methodology that uses information and technology to manage variability in a field with the goal of generating optimum profits.

<u>Explanation:</u>

Precision farming (PA), also referred to as "prescription farming" or "variable rate agriculture," is a collection of methods that can be applied in many agricultural science areas.Spatial planning may result in the more efficient use of resources that support the firm's productivity and the management of valuable resources.

PA can be described as a current management technique for the regulation of agricultural practices based on georeferenced data. It is focused on describing the georeferenced details by applying surveillance procedures and incorporating soil, plant, and environment morphology.

what does the statment mean. The properties of salts are different from the properties of the elements that go into making them
Olegator [25]
Think of it this way,
Mix Iron and sulphur in a bowl. How do you separate them? Use a magnet right. Yes.

Now, mix the iron and sulphur together but know, heat them up. Let them cool for a while. After that, use a magnet to separate. You cant. This is because the compound (FeS) now has a different property from its original components.

Apply this theory onto salts.

A) Compute the repeat unit molecular weight of polystyrene. B) Compute the number-average molecular weight for a polystyrene for
Andrej [43]

Answer:

Explanation:

In Polystrene, the molecular formula for the repeat unit = C_8H_8;

and the atomic weights of Carbon C = 12.01 g/mol

For Hydrogen, it is 1.01 g/mol

Hence, the repeat unit molecular weight is:

m = 8 (12.01 g/mol)+8(1.01 g/mol)

m = 96.08 g/mol + 8.08 g/mol

m = 104.16 g/mol

The degree of polymerization = no-average molecular weight/repeat unit molecular weight.

Mathematically;

DP = \dfrac{\overline M_n}{m}

\overline M_n= DP \times m

\overline M_n= 25000 \times 104.16 \ g/mol

\overline M_n= 2604000  \ g/mol
