A homogeneous mixture has the same uniform appearance and composition throughout. Many homogeneous mixtures are commonly referred to as solutions. A heterogeneous mixture consists of visibly different substances.
97.2g H20 x 1mole/18g of H2O x 6.022x10^23 molecules/1mole= 3.25 x10^24 molecules of H2O
hope this helps! :)
Answer:
The pressure is 16, 9 atm
Explanation:
We use the formula PV=nRT. The temperature in Kelvis is: 273 + 25 = 298K
PV=nRT P =(nRT)/V
P= (0, 450 mol x 0,082 l atm/K mol x 298)/0,650 l= 16, 91723077atm
Explanation:
Unsustainable way of managing resources means using resources in an unjustifiable manner, using without keeping in the needs for future generations. That is disobeying the principles of sustainability.
For examples release of toxic industrial wastes in rivers and thus, polluting it. Or, Deforestation of land for agricultural or industrial purposes. Thus, reducing the oxygen carrying capacity of Earth.
