<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.
In an atom, the protons, which have a positive charge, and the neutrons, which have a neutral charge, are located in the nucleus. The electrons, which have a negative charge, orbit the nucleus of the atom.
Answer:
3.2 x 10²¹molecules
Explanation:
Given parameters:
Volume of nitrogen gas = 120cm³
Unknown:
Mass of nitrogen gas = ?
Number of molecules = ?
Solution:
To solve this problem, note that;
1 mole of gas occupies a volume of 22.4L at STP
Now;
convert 120cm³ to L ;
1000cm³ = 1L
120cm³ gives 0.12L
Since;
22.4L of gas has 1 mole at STP
0.12L of gas will have 
= 0.0054mole at STP
So;
Mass of N₂ = number of moles x molar mass
Molar mass of N₂ = 2(14) = 28g/mol
Mass of N₂ = 0.0054 x 28 = 0.15g
Now;
1 mole of a gas will have 6.02 x 10²³ molecules
0.0054 mole of N₂ will contain 0.0054 x 6.02 x 10²³ =
3.2 x 10²¹molecules
Hello!! Your atomic mass will be found at the bottom of each element. The atomic mass of Nitrogen is 14.007. Have a great day!!
1000dm = 0.1 km
