Answer:
he free energy goes down as the water freezes. Here are the important terms: The energy of the interactions between the water molecules goes down as they line up in the stable ice positions. This lost energy flows out into the environment as heat, increasing the entropy of
Explanation:When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice. ... As the liquid cools down, the amount of potential energy is reduced and the molecules start to move slower. When the water temperature reaches around 0°C, the molecules stick together and form a solid – ice
Answer:
16.499 × 10∧ 21 atoms
Explanation:
Given data:
mass of P2O5= 0.560 g
number of atoms= ?
first of all we will calculate the molar mass of P2O5:
P = 2×31 g/mol = 62 g/mol
O = 5× 16 = 80 g/mol
molar mass of P2O5 = 142 g/mol
Noe we will find the moles of 0.560 g P2O5:
moles = mass / molar mass
moles = 0.560 g/ 142 g/mol
moles = 0.0039 mol
now we will find the atoms present in 0.0039 moles:
0.0039 × 6.02 × 10∧ 23 molecules
2.357 × 10∧ 21 molecules
P2O5 consist of 7 atoms:
2.357 × 10∧ 21 × 7 = 16.499 × 10∧ 21 atoms
Farm water runoff, which causes nitrogen rich fertilizer to be washed into the body of water. The nitrogen feeds the algae bloom.. Hope this helps
