Answer:

Point source pollution:

If pollution comes from a fix source then is called point source pollution.It have a specific location where pollution comes.

Ex: Air pollution ,water pollution.

Non point source pollution:

If pollution comes from number of sources then is called point source pollution.This pollution does not have a specific point of source.

Ex: Spills ,leaks ,Sewage over flow etc.

Answer:

Defined as under.

Explanation:

A point source pollution is a single identifiable source of pollutants like air, water, thermal and light. And has a negligible extent, distinguishes from other geometric or area sources of nonpoint, etc.

While nonpoint source pollution is derived from various sources. Such as results of land runoff. atmospheric drainage and seepage they may affect a body of water such as from the agricultural areas draining to a river.

Various pathogens and viruses found in the body of water, also the presence of poorly managed livestock, pets, and other these problems is also elated to the urban and rural asphalt and concrete, highway runoff and mining activities.

[Given] 25.0 g Au

[Solve] moles Au

<u>Step 2: Identify Conversions</u>

[PT] Molar Mass of Au - 196.97 g/mol

<u>Step 3: Convert</u>

[DA] Set up: $\displaystyle 25.0 \ g \ Au(\frac{1 \ mol \ Au}{196.97 \ g \ Au})$
[DA] Multiply/Divide [Cancel out units: $\displaystyle 0.126923 \ mol \ Au$

<u>Step 4: Check</u>

<em>Follow sig fig rules and round. We are given 3 sig figs.</em>

0.126923 mol Au ≈ 0.127 mol Au

An ideal gas contained in a piston-cylinder assembly is compressed isothermally in an internally reversible process.

Tju [1.3M]

Answer:

a) $\Delta S$

b) entropy of the sistem equal to a), entropy of the universe grater than a).

Explanation:

a) The change of entropy for a reversible process:

$\delta S=\frac{\delta Q}{T}$

$\Delta S=\frac{Q}{T}$

The energy balance:

$\delta U=[tex]\delta Q- \delta W$

If the process is isothermical the U doesn't change:

$0=[tex]\delta Q- \delta W$

$\delta Q= \delta W$

$Q= W$

The work:

$W=\int_{V1}^{V2}P*dV$

If it is an ideal gas:

$P=\frac{n*R*T}{V}$

$W=\int_{V1}^{V2}\frac{n*R*T}{V}*dV$

Solving:

$W=n*R*T*ln(V2/V1)$

Replacing:

$\Delta S=\frac{n*R*T*ln(V2/V1)}{T}$

$\Delta S=n*R*ln(V2/V1)}$

Given that it's a compression: V2<V1 and ln(V2/V1)<0. So:

$\Delta S$

b) The entropy change of the sistem will be equal to the calculated in a), but the change of entropy of the universe will be 0 in a) (reversible process) and in b) has to be positive given that it is an irreversible process.
