You need to have 8 electrons to fill an atom and to fill bond the pairs need to equal 8
The plant that should be moved here to protect from malnourishment is plant 3. The correct option is C.
<h3>What is visible spectrum?</h3>
The visible light spectrum is the portion of the electromagnetic spectrum that can be seen by the human eye. Simply put, this range of wavelengths is known as visible light.
The visible spectrum, also known as the optical spectrum, is the portion of the electromagnetic spectrum whose radiation consists of photons capable of sensitizing a normal person's human eye. The corresponding visible light radiation range is identified.
That being said, plant 3 is situated in front of a green stained glass window.
Plants have chlorophyll pigment that reflects back green light, making green light less effective for photosynthesis and causing them to die as quickly as if they were kept in the dark.
Thus, the correct option is C.

Answer:
The correct equation to calculate the heat of this reaction is:
ΔH = m*s*∆T
Explanation:
During any chemical reaction, heat can either be absorbed from the environment or released to the environment through the reaction. The heat exchange between a chemical reaction and its environment is known as the reaction enthalpy, or H. However, H cannot be measured directly; the change in temperature of a reaction over time is used to find the enthalpy change over time (denoted as ΔH).
In general ΔH = m*s*∆T, where m is the mass of the reactants, s is the specific heat of the product, and ΔT is the change in the reaction temperature.
Answer:
16.89 atm.
Explanation:
Step 1:
Data obtained from the question
Number of mole (n) = 2.3 mol
Temperature (T) = 40°C = 40°C + 273 = 313K
Volume (V) = 3.5L
Pressure (P) =..?
Gas constant (R) =0.0821 atm.L/Kmol
The pressure exerted by the gas can be obtained by using the ideal gas equation as shown below:
PV = nRT
Divide both side by V
P = nRT /V
P = 2.3 x 0.0821 x 313 / 3.5
P = 16.89 atm.
Therefore, the pressure exerted by the gas is 16.89 atm.
