Answer
There are 17 nutrients that essential for the growth of the plants. These nutrients are classified into two categories on the basis of requirement micronutrients (required in less amount) and macronutrient (required in large amount). The three primary nutrients needed for plant growth are nitrogen, phosphorous and potassium.
<h3><u>Answer;</u></h3>
Partial pressure of Ar = 92.934 kPa
<h3><u>Explanation;</u></h3>
Partial pressure of a gas = Mole fraction × Total pressure
Mole fraction = Number of moles of a gas /Total moles of gas
Therefore;
Mole fraction of Ar = 0.211 mol/ (0.211 + 0.150)
= 0.5845
Total pressure = 159 kPa
Hence;
Partial pressure of Ar = 0.5845 × 159 kPa
<u> = 92.934 kPa</u>

c.Both the breaking of nuclear bonds and the forming of nuclear bonds.
Explanation:
Nuclear energy is released by the breaking and forming of nuclear bonds. The breaking of nuclear bonds by unstable atoms is known as nuclear fission. The forming of nuclear bonds by combination of light atoms is known as nuclear fusion.
- Nuclear fission is a radioactive decay process in which a heavy nucleus spontaneously disintegrates into lighter ones with the release of energy.
- In nuclear fusion, atomic nuclei combines into larger ones with the release of large amount of energy.

Answer: 149
Explanation:
Using the ideal gas equation; PV = nRT
P= Pressure = 0.910 atm, T= Temperature = ?
V= Volume = 4.0L R = Gas constant = 0.08206 L.atm/mol/K
n = number of moles = 0.297
Making 'T' the subject of the formular, we have;
T = P V/ n R = 0.910 x 4 / 0.297 x 0.08206
= 149
