Answer:
4.31 atm.
Explanation:
- We can use the general law of ideal gas: <em>PV = nRT.</em>
where, P is the pressure of the gas in atm.
V is the volume of the gas in L.
n is the no. of moles of the gas in mol.
R is the general gas constant,
T is the temperature of the gas in K.
- If n and V are constant, and have different values of P and T:
<em>(P₁T₂) = (P₂T₁)</em>
<em></em>
P₁ = 3.81 atm, T₁ = 25°C + 273 = 298 K,
P₂ = ??? atm, T₂ = 50°C + 273 = 323 K,
- Applying in the above equation
(P₁T₂) = (P₂T₁)
<em>∴ P₂ = (P₁T₂)/(T₁)</em> = (3.81 atm)(323 K)/(298 K) = <em>4.31 atm.</em>
One mole of NaOH (Sodium hydroxide) is equal to 39.997 grams of NaOH.
A nuclear reaction in which a heavy nuclear splits spontaneously or on impact with another particle with the release of energy- fission
A nuclear reaction in which atomic nucleus with the release of energy-fusion
The energy harnessed in nuclei is released in nuclear reaction. Fission is the splitting of a heavy nucleus into lighter nuclei and fusion is the combining of nuclei to form a bigger and heavier nucleus
Answer:
The two structures that will provide positive identification of a plant cell under a microscope are I think C. cell wall and chloroplast.
Explanation:
Plant cells have some cell organelles which is unique to them, these organelles are not found in animal cells. Examples of such organelles are chloroplasts, large central vacuole, cell wall, etc.
