Answer:
200 °C
Explanation:
Let’s convert all the temperatures to the same scale, say, Celsius.
<em>Celsius</em>
Water boils at 100 °C, so 200 °C is the temperature of <em>superheated steam</em>.
<em>Fahrenheit
</em>
Water boils at 212 °F, so 200 °F is <em>just below the boiling point of water</em>.
<em>Kelvin
</em>
Standard temperature is 0 °C = 273.15 K. Ice melts at 273.15 K (0 °C), so
200 K is <em>well below the melting point of ice</em>.
C = K – 273.15
C = 200 -273.15 = -73 °C
Thus, 200 °C is the hottest temperature.
The number of sigma and pi bonds are,
Sigma Bonds =
16 Pi Bonds =
3Explanation: Every first bond formed between two atoms is sigma. Pi bond is formed when already a sigma bond is there. While in case of Alkyne (triple Bond) there is one sigma and one pi bond already present, so the third bond is formed by second side-to-side overlap of orbitals, hence, a second pi bond is formed.
Below all black bonds are sigma bonds, while in alkene there is one pi bond and in alkyne there are two pi bonds.

Answer:
The water falls to the earth as precipitation, such as rain, hail, sleet, and snow. When precipitation reaches the earth's surface, some of it will flow along the surface of the land and enter surface water like lakes, streams, and rivers, as runoff. The rest of it soaks or percolates into the soil, called
Answer:
Number of moles of oxygen used=13.5moles
Explanation:
To know the number of moles of oxygen used, first calculate the molar mass of water.
H2O=(2*1)+(1*16)
=2+16
18g/mol of H2O
The moles of H2O is 7.6 moles
So first, find the molar mass of oxygen
O2=2*16
=32g/mol
Then, number of moles of oxygen is equal to molar mass of oxygen divide by the molar mass of water times the number of moles of water
No. moles of O2=[32g/mol]/[18g/mol] *7.6moles
Moles of O2=1.778*7.6moles
No.moles of O2=13.5 moles
Therefore, the number of moles of oxygen used was 13.5moles
