Answer:
picture not bright
Explanation:
please a brainliest for tge feedback
The reasonable ground-state electron configuration is: 1s2 2s2 2p6 3s2 3p6 4s2 4d8
The species bonds with the most ionic character is the compound with elements that develop the higher electronegativity difference between each other.
the most ionic character had maximum EN.
EN is max for SiO2
hope this help
Answer:
2.5 atm
Explanation:
V1 = 28L
T1 = 45°C = (45 + 273.15)K = 318.15K
V2 = 34L
T2 = 35°C = (35 + 273.15)K = 308.15k
P2 = 2.0atm
P1 = ?
From general gas equation,
(P1 × V1) / T1 = (P2 × V2) / T2
P2 × V2 × T1 = P1 × V1 × T2
P1 = (P2 × V2 × T1) / (V1 × T2)
P1 = (2.0 × 34 × 318.15) / (28 × 308.15)
P1 = 21634.5 / 8628.2
P1 = 2.5 atm
The initial pressure of the gas is 2.5atm
