<span>The scientific knowledge that
was necessary for Schrodinger’s work is the Bohr’s model. Unlike the Bohr
model, the quantum model does not define the exact path of an electron. The electron
is likely to be in a less dense area of cloud.</span>
Answer:
Lewis acid is a substance that donates a lone-pair of electrons.
Explanation:
What is said in the statement corresponds to a Lewis base, not an acid. For example, NH3 is a Lewis base, since it is capable of donating its pair of electrons. Trimethylborane (Me3B) is a Lewis acid, since it is capable of accepting a solitary pair.
Answer:
Initial temperature = T₁ = -96.65 °C
Explanation:
Given data:
Initial volume = 4.5 L
Final temperature = 80°C (80+273 = 353 K)
Final volume = 9.0 L
Initial temperature = ?
Solution:
According to Charles law, The volume of given amount of a gas is directly proportional to its temperature at constant number of moles and pressure.
Mathematical expression:
V₁/T₁ = V₂/T₂
V₁ = Initial volume
T₁ = Initial temperature
V₂ = Final volume
T₂ = Final temperature
Now we will put the values in formula.
V₁/T₁ = V₂/T₂
T₁ = V₁ T₂/V₂
T₁ = 4.5 L × 353 K / 9.0 L
T₁ = 1588.5 L.K / 9.0 L
T₁ = 176.5 K
Kelvin to °C:
176.5 K - 273.15 = -96.65 °C
