Answer:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
Explanation:
Abbreviated and unabbreviated electronic configuration:
The abbreviated electronic configuration uses the noble gas configuration i.e complete electronic shells. For example, the atomic number of neon is ten and sodium is eleven. The abbreviated electronic configuration of sodium is written by using the neon abbreviation in following way:
The electronic configuration of neon is given below:
Ne₁₀ = 1s² 2s² 2p⁶
The abbreviated electronic configuration of sodium:
Na₁₁ = [Ne] 3s¹
While the unabbreviated electronic configuration is written without using noble gas electronic configuration.
Unabbreviated electronic configuration of sodium:
Na₁₁ = 1s² 2s² 2p⁶ 3s¹
Answer:
Explanation:
The formula for the amount heat q absorbed by a substance is
q = mcΔT
where
m = the mass of the substance
C = the specific heat capacity of the material
ΔT = the temperature change
Data:
q = 2267 J
m = 44.5 g
T₁ = 33.9 °C
T₂ = 288.3 °C
Calculations:
ΔT = (288.3 - 33.9) °C = 254.4 °C
Answer:
Air temperature is not accurate but it can measure by the air is cold or hot
