<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.

How much positive charge is in 1.4 kg of oxygen? The atomic weight (15.9994 g) of oxygen contains Avogadro’s number of atoms, wi

Cerrena [4.2K]

Answer:

$6.7511\times 10^7\ C$

Explanation:

The atomic weight of oxygen = 15.9994 g

This mass corresponds to 1 mole of the oxygen atoms.

Thus,

15.9994 g mass of oxygen contains $6.02\times 10^{23}$ atoms of oxygen.

1.4 kg = 1400 g ( 1 kg = 1000 g)

So,

1400 g mass of oxygen contains $\frac {6.02\times 10^{23}}{15.9994}\times 1400$ atoms of oxygen.

Number of atoms in 1400 g of oxygen = $526.769754\times 10^{23}$

Also, 1 atom of oxygen contains 8 protons

Charge of 1 proton = + $1.602\times 10^{-19}\ C$

So, Charge on 1 atom of oxygen = $8\times 1.602\times 10^{-19}\ C$

Thus,

Charge on $526.769754\times 10^{23}$ atoms of oxygen = $526.94476\times 10^{23}\times 8\times 1.602\times 10^{-19}\ C=6.7533\times 10^7\ C$

Thus, positive charge in 1.4 kg of oxygen = $6.7511\times 10^7\ C$

At a particular temperature, an equilibrium mixture the reaction below was found to contain 0.171 atm of I2, 0.166 atm of Cl2 an

maw [93]

Answer: 3390

Explanation:

Since this problem already gives is the equilibrium values, all we have to do is to plug them into the formula for $K_{p}$ .

$K_{p} =\frac{[ICl]^2}{[I_{2}][Cl_{2}] }$

$K_{p} =\frac{(9.81)^2}{(0.171)(0.166)} =3390$
