Answer:
The change in entropy of gas is
Explanation:
n= Number of moles of gas
Change in entropy of gas =
From the given,
Let "T" be the initial temperature.
Therefore, The change in entropy of gas is
1) determine molar mass of K₃PO₄
2) determine total mass of potassium atoms in K₃PO₄
4) divide by molar mass and multiply by 100

Both abiotic and biotic components of the Earth's system, particularly the biosphere, hydrosphere, and geosphere, phosphorus. Phosphorus cycle cannot be found in the gaseous state in air, in contrast to the compounds of other matter cycles.
This is due to the fact that phosphorus is typically liquid at standard pressures and temperatures. It mostly cycles through sediments, water, and soil. Phosphorus is primarily present in the environment as very minute dust particles. Phosphorous can also be delivered by water or wind in the form of phosphate (both abiotic). Living plants absorb phosphorus, and these plants can either die and be degraded by other living species or they can die and be consumed by other living organisms.

Answer:
Part A. Mass = 0.12 g of NaCl
Part B. Mass = 0.41 g of Pb
Explanation:
Part A. We verify the moles
2×10⁻³ moles of NaCl
Let's determine the molar mass → Molar mass Na + Molar mass Cl
23 g/mol + 35.45 g/mol = 58.45 g/mol
We convert moles to g → 2×10⁻³ mol . 58.45 g/mol = 0.11 g
Part B. → 2×10⁻³ moles of Pb; Molar mass = 207.2 g/mol
We convert moles to g → 2×10⁻³ mol . 207.2 g/mol = 0.41 g of Pb
