Which anthropogenic pollutants are implicated in the formation of most acidic precipitation? 1. carbon oxides 2. ozone and carbo
VashaNatasha [74]

Answer:

nitrogen oxides and sulphur oxides

Explanation:

Factors responsible for antropogenic pollution are:

  • burning of fossil fuels
  • deforestation
  • mining
  • sewage
  • industrial effluent
  • pesticides, fertilizers, etc.  

The primary air pollutants released from burning of fossil fuels are oxides of nitrogen, sulfur oxides and carbon monoxide.

Out of which the main pollutants that are responsible for acidic precipitation are oxides of nitrogen and sulfur oxides.

Sulfur oxides and Oxides of nitrogen reacts with moisture present in the air to form sulfuric acid and nitric acid respectively.

These acids get mixed with rain and cause acidic precipitation.

Therefore, the correct option is oxides of nitrogen and sulfur oxides.

Why is a chemical equilibrium described as dynamic?
Mariulka [41]

Answer:

Chemical equilibrium is also called as dynamic equilibrium because it in chemical equilibrium, the equilibrium can shift towards both sides that is reactant and product known as equilibrium shifting.

Which of these statements describes this mathematical equation?
salantis [7]

Answer:

The final pressure of a gas is inversely proportional to the volume change and directly proportional to temperature

Explanation:

Given

\frac{P_1V_1}{T_1} = k

Required

Interpret

\frac{P_1V_1}{T_1} = k

Multiply both sides by T1

T_1 * \frac{P_1V_1}{T_1} = k * T_1

P_1V_1 = kT_1

Divide both sides by V1

\frac{P_1V_1}{V_1} = \frac{kT_1}{V_1}

P_1 = \frac{kT_1}{V_1}

This can be rewritten as:

P_1 = k\frac{T_1}{V_1}

In the above expression; k is a constant of proportionality.

So, the equation can be written as variation as follows:

P_1\ \alpha\ \ \frac{T_1}{V_1}

To interpret:

<em>P varies directly to T (the numerator) and inversely to V (the denominator).</em>
