Answer:
Even though plants are rooted in the ground, they still move, exert force, and do work.
Plant cells have very strong cell walls that allow pressure to build up inside of the cell as water is absorbed. This pressure is called turgor.
When turgor pressure is high enough in a cell, the cell walls become firm and as a result, the cell becomes rigid and the plant is able to stand tall and straight.
When a plant does not get enough water, the turgor pressure inside of the cells decreases. A decrease in pressure pushing against the cell wall causes the cells to lose their shape and shrink. This causes the plant to begin to droop or wilt.
When the wilted plant gets enough water, the cells will become rigid again, and the plant will stand firm and straight once again.

In if the reaction below 49 grams of Fe3O4 produces a 78.25% yield of Fe. How many grams are produced? Fe3O4 + 4H2 = 3Fe + 4H2O
Imagine the = is an arrow
Fe produced : 27.53 g
Further explanationReaction
Fe₃O₄ + 4H₂ = 3Fe + 4H₂O
mol Fe₃O₄ (MW=233.55 g/mol) :
[tex]\tt \dfrac{49}{233.55 g/mol}=0.21[/tex]
mol ratio Fe₃O₄ : Fe = 1 : 3, so mol Fe :
[tex]\tt 3\times 0.21=0.63~g/mol[/tex]
mass Fe(Ar=55,845 g/mol)
[tex]\tt 0.63\times 55,845=35.18~g[/tex]
grams produced :
[tex]\tt \%yield=\dfrac{actual}{theoretical}\times 100\%\\\\actual=\%yield\times theoretical\\\\actual=78.25\%\times 35.18\\\\actual=27.53~g[/tex]

The density of the sample : 0.827 g/L
Further explanationIn general, the gas equation can be written
[tex]\large {\boxed {\bold {PV = nRT}}}[/tex]
where
P = pressure, atm , N/m²
V = volume, liter
n = number of moles
R = gas constant = 0.082 l.atm / mol K (P= atm, v= liter),or 8,314 J/mol K (P=Pa or N/m2, v= m³)
T = temperature, Kelvin
n= 1 mol
MW Neon = 20,1797 g/mol
mass of Neon :
[tex]\tt mass=mol\times MW\\\\mass=1\times 20,1797 =20.1797~g[/tex]
The density of the sample :
[tex]\tt \rho=\dfrac{m}{V}\\\\\rho=\dfrac{20,1797}{24.4}=0.827~g/L[/tex]
or We can use the ideal gas formula ta find density :
[tex]\tt \rho=\dfrac{P\times MW}{RT}\\\\\rho=\dfrac{1\times 20.1797}{0.082\times 298}\\\\\rho=0.826~g/L[/tex]
