Answer:
3°F, 0°F, -11°F, -16°F, -20°F
Explanation:
The Fahrenheit scale is a temperature scale proposed in 1724 by the physicist Daniel Fahrenheit.
In this scale:
- The freezing point of water is set at 32 degrees
- The boiling point of water is set at 212 degrees
One degree in the Fahrenheit scale is indicated with the symbol .
The equivalence between temperature in Celsius degrees and Fahrenheit degrees is as follows:
to convert from Fahrenheit to Celsius
to convert from Celsius to Fahrenheit
The Fahrenheit scale is an increasing monotonic scale, it means that temperature goes from negative values towards positive values without interruption. Therefore, the temperatures listed from warmest to coldest are:
3°F, 0°F, -11°F, -16°F, -20°F
Answer:
1 .
2.
Explanation:
The more stable the ionic compound, the more is it lattice energy.
- The more the charge on the cation and the anion, the greater is the lattice energy.
- The less the size of the cation and the anion, the greater is the lattice energy.
Scandium oxide () is an oxide in which
behaves as cation and
behaves as anion.
The compounds which has higher lattice energy than scandium oxide are:
1 .
This is because the charge are same on the cation and the anion as in the case of the Scandium oxide but the size of the cation is smaller than
. Thus, this corresponds to higher lattice energy.
2.
This is because the charge on the cation is greater than that of
and also the size of the cation
is smaller than
. Thus, this corresponds to higher lattice energy.
