-Photons are absorbed by hot gas atoms
-Energy is transferred through large-scale movement of material
-Energy is released into the photosphere
N=9.933
Explanation:
no of mole = m÷mr
then ,no of molecules=n×la
The answer is; the average annual precipitation on Earth equals the amount of water that evaporates
This water cycle is also known as the hydrological cycle. At any one moment in the cycle, there is water lost from the biosphere to the atmosphere through evapotranspiration. The water in the atmosphere also precipitates back to earth surface as rain or snow and the cycle continues.
in per unit time some things velocity changes rate is called acceleration
Answer:
0.03
Explanation:
22.8 g Ba(OH)2 (1 mol Ba (OH)2/ 171.34 g) = 0.133 mol Ba (OH)2
77.2 g H2O (1 mol H2O/18 g) = 4.29 mol H2O
X= molar fraction= mol Ba(OH)2/ mol total
X= 0.133/ (0.133+4.29) = 0.03
