Answer: 25.5°C
Explanation: take the average of the reading i.e (25 + 26)/2= 25.5
Answer:
NH3
Explanation:
Which salt is least soluble at 90 degrees Celsius
A, O2 has to be a reactant for combustion to burn
There are six electrons in the covalent bonds.
Two N atoms would be :N:· + ·:N:
An N₂ molecule would be :N:::N: or :N≡N:
This gives each N atom an octet of eight electrons in its valence shell.
Delta T= T final - T initial
Tfinal= -101.1 °C
Tinitial= -0.5 °C
•Delta T = -101.1°C - (-0.5°C)
=100.6°C
Kelvin= °C + 273
= -100.6 + 273
= 172.4 Kelvin
