Answer:
Q = 25360.269 j
Explanation:
Given data:
Mass = 165 g
Initial temperature = 10.55 °C
Final temperature = 47.32°C
Energy absorbed = ?
Solution:
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = T2 - T1
ΔT = 47.32°C - 10.55 °C
ΔT = 36.77 °C
Q = m.c. ΔT
Q = 165 g . 4.18 j/g.°C . 36.77 °C
Q = 25360.269 j

Answer:
Resonance structures are represented in the picture below.
Explanation:
When there is a double pair of electrons shared between atoms in a molecule, the position of these electrons can be changed, without changing the molecule conformation. This occurs to stabilization, the electrons are relocated. These structures are called resonance structures.
In the molecule of NO₂F, nitrogen has 5 electrons in its valence shell, so it needs 3 electrons to be stable. Oxygen has 6 electrons and needs 2 to be stable, and fluor has 7 electrons and needs one electron to be stable.
Nitrogen still has electrons after the sharing, so it can also share one pair and will have a partial positive charge. One of the oxygens will not complete the octet, so will share only one pair f electron and will have a partial negative charge, that will compensate the positive charge in nitrogen.
The two resonance structures are shown below:
A. covalent compounds are the combination of two or more non metals
